Water:

This is a very good article. Not only about the warm water after your meal,
but about Heart Attack’s . The Chinese and Japanese drink hot tea with their
meals, not cold water, maybe it is time we adopt
their drinking habit while
eating. For those who like to drink cold water, this
article is applicable to
you. It is very Harmful to have Cold Drink/Water during a meal. Because,
the cold water will solidify the oily stuff that you
have just consumed. It will
slow down the digestion. Once this ‘sludge’
reacts with the acid, it will break down and be
absorbed by the intestine faster than the solid food. It will line the intestine. Very soon, this will turn into fats
and lead to cancer . It is best to drink hot soup
or warm water after a meal.

French fries and Burgers
are the biggest enemy of heart health. A coke after that gives more power to
this demon. Avoid them for
your Heart’s & Health.

Drink one glass of warm water just when you are about to go to bed to avoid clotting of the blood at night to avoid heart attacks or strokes.

Visual field testing

What is visual field testing?

As you focus on the words in this article, how much can you see out of the corners of your eyes? Can you tell what’s happening in your surroundings?

Your visual field is how wide of an area your eye can see when you focus on a central point. Visual field testing is one way your ophthalmologist measures how much vision you have in either eye, and how much vision loss may have occurred over time.

Visual field testing can detect blind spots

A visual field test can determine if you have blind spots (called scotoma) in your vision and where they are. A scotoma’s size and shape can show how eye disease or a brain disorder is affecting your vision. For example, if you have glaucoma, this test helps to show any possible side (peripheral) vision loss from this disease.

Ophthalmologists also use visual field tests to assess how vision may be limited by eyelid problems such as ptosis and droopy eyelids.

Six types of visual field tests

1. Confrontation visual field test

A common way for your doctor to screen for any problems in your visual field is with a confrontation visual field test. You will be asked to look directly at an object in front of you, (such as the doctor’s nose) while one of your eyes is covered. Your doctor may hold up different numbers of fingers in areas of your peripheral (side) vision field and ask how many you see as you look at the target in front of you.

2. Automated static perimetry test

To check for a suspected eye problem or monitor the progress of an eye disease, your ophthalmologist will rely on more specific tests to measure how you see objects in your field of vision. The automated static perimetry test is used for this purpose. It helps create a more detailed map of where you can and can’t see.

To do this test, you will look into the center of a bowl-shaped instrument called a perimeter. The eye not being tested will be covered with a patch. The testing eye will have your lens prescription placed in front of it to make sure you are seeing as well as possible.

A patient sits at a perimeter machine taking a visual field exam.

You will be asked to keep looking at a center target throughout the test. Small, dim lights will begin to appear in different places throughout the bowl, and you will press a button whenever you see a light. The machine tracks which lights you did not see.

You may blink normally during the test. You may also pause the test if you feel you need to take a break for a moment.

Because you are looking straight ahead during the test, your doctor can tell which lights you see outside of your central area of vision. Since glaucoma affects peripheral vision, this test helps show if there is vision loss outside of your central visual field.

This is called a “static” test because the lights do not move across the screen, but blink at each location with differing amounts of brightness. This allows the machine to find the dimmest light you can see at each location in your peripheral vision.

The machine will show some lights that are too dim for you to see. This is done deliberately to find what is called the “visual threshold” of each location, meaning the brightness that you have trouble seeing half the time. You may be concerned because you can’t see every light. Rest assured that this is how the test is supposed to work.

3. Kinetic visual field test

In some cases, you may have a test called kinetic visual field testing. While it is similar to the perimetry testing process described above, the kinetic test uses moving light targets instead of blinking lights.

4. Frequency doubling perimetry

Another way your ophthalmologist can assess loss of vision is using something called frequency doubling perimetry. It uses an optical illusion to check for damage to vision. Vertical bars (usually black and white) appear on the perimeter screen. These bars will flicker at varying rates. If you are not able to see the vertical bars at certain times during the test, it could show vision loss in certain parts of your visual field.

5. Electroretinography

To check for visual field loss from certain retina conditions, your ophthalmologist may also use electroretinography (ERG). This test measures the electrical signals of light-sensitive cells in the retina called photoreceptors as well as other cells. To do this test, your eyes are dilated and you will also be given numbing eye drops. Your eyes are held open with instrument called a speculum. A tiny device called an electrode is placed on your cornea. You will look into a bowl-shaped machine at flashing or varying patterns of light. The electrode measures your eye’s electrical activity in response to the light.

6. Amsler grid: A basic visual field test for central vision

People who have age-related macular degeneration (AMD) are familiar with one very basic type of visual field test: the Amsler grid. It is a pattern of straight lines that makes a grid of many equal squares. You look at a dot in the middle of the grid and describe any areas that may appear wavy, blurry or blank.Amsler Grid, used at home daily to track vision changes in people with some eye conditions like AMD or toxoplasmosisAmsler Grid

The Amsler grid is commonly used at home by people with AMD. This test only measures the middle of the visual field, but is a simple yet helpful tool for monitoring vision changes.

How do you know if you need visual field testing?

Visual field testing is an important part of regular eye care for people who are at risk for vision loss from disease and other problems.

People with the following conditions should be monitored regularly by their ophthalmologist, who will determine how often visual field testing is needed:

  • Glaucoma
  • Multiple sclerosis
  • Thyroid eye disease (Graves’ disease)
  • Pituitary gland disorders
  • Central nervous system problems (such as a tumor that may be pressing on visual parts of the brain)
  • Stroke
  • Long-term use of certain medications (such as Plaquenil, or hydroxychloroquine, which requires yearly visual field checkups)

People with diabetes and high blood pressure have a greater risk of developing blocked blood vessels in the optic nerve and retina. They may need visual field testing to monitor any effects of these conditions on their vision.

If your visual field is limited, your ability to drive may be in jeopardy. If you are concerned about vision loss or your ability to continue driving, talk with an eye care practitioner.

You can have your visual field testing at Eyeupdate Eye clinic, 01, Ajuwon bus stop, Akute-Ajuwon Road via Iju Ishaga.

How to prevent vision loss

Follow these simple guidelines for maintaining healthy eyes well into your golden years.

Your eyes are an important part of your health. You can do many things to keep them healthy and make sure you’re seeing your best. Follow these simple guidelines for maintaining healthy eyes well into your golden years.

Have a comprehensive dilated eye exam. You might think your vision is fine or that your eyes are healthy, but visiting your eye care professional for a comprehensive dilated eye exam is the only way to really be sure. When it comes to common vision problems, some people don’t realize they could see better with glasses or contact lenses. In addition, many common eye diseases, such as glaucoma, diabetic eye disease, and age-related macular degeneration, often have no warning signs. A dilated eye exam is the only way to detect these diseases in their early stages.

During a comprehensive dilated eye exam, your eye care professional places drops in your eyes to dilate, or widen, the pupil to allow more light to enter the eye—the same way an open door lets more light into a dark room. This process enables your eye care professional to get a good look at the back of the eyes and examine them for any signs of damage or disease. Your eye care professional is the only one who can determine if your eyes are healthy and if you’re seeing your best.

Maintain your blood sugar levels. 90% of blindness caused by diabetes is preventable. Ask your health care team to help you set and reach goals to manage your blood sugar, blood pressure, and cholesterol—also known as the ABCs of diabetes.

  • A1c: The goal set for many people is less than 7% for this blood test, but your doctor might set different goals for you.
  • Blood pressure: High blood pressure causes heart disease. The goal is less than 140/90 mmHg for most people, but your doctor might set different goals for you.
  • Cholesterol: LDL or “bad” cholesterol builds up and clogs your blood vessels. HDL or “good” cholesterol helps remove the “bad” cholesterol from your blood vessels. Ask what your cholesterol numbers should be.

Know your family’s eye health history. Talk to your family members about their eye health history. It’s important to know if anyone has been diagnosed with an eye disease or condition, since many are hereditary. This information will help to determine if you’re at higher risk for developing an eye disease or condition.

Eat right to protect your sight. You’ve heard that carrots are good for your eyes. But eating a diet rich in fruits and vegetables—particularly dark leafy greens, such as spinach, kale, or collard greens—is important for keeping your eyes healthy, too.i Research has also shown there are eye health benefits from eating fish high in omega-3 fatty acids, such as salmon, tuna, and halibut.

Maintain a healthy weight. Being overweight or obese increases your risk of developing diabetes and other systemic conditions, which can lead to vision loss, such as diabetic eye disease or glaucoma. If you’re having trouble maintaining a healthy weight, talk to your doctor.

Wear protective eyewear. Wear protective eyewear when playing sports or doing activities around the home. Protective eyewear includes safety glasses and goggles, safety shields, and eye guards specially designed to provide the correct protection for the activity in which you’re engaged. Most protective eyewear lenses are made of polycarbonate, which is 10 times stronger than other plastics. Many eye care providers sell protective eyewear, as do some sporting goods stores.

Quit smoking or never start. Smoking is as bad for your eyes as it is for the rest of your body. Research has linked smoking to an increased risk of developing age-related macular degeneration, cataract, and optic nerve damage, all of which can lead to blindness.ii, iii

Be cool and wear your shades. Sunglasses are a great fashion accessory, but their most important job is to protect your eyes from the sun’s ultraviolet rays. When purchasing sunglasses, look for ones that block out 99 to 100 percent of both UV-A and UV-B radiation.

Give your eyes a rest. If you spend a lot of time at the computer or focusing on any one thing, you sometimes forget to blink and your eyes can get fatigued. Try the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds. This short exercise can help reduce eyestrain.

Clean your hands and your contact lenses—properly. To avoid the risk of infection, always wash your hands thoroughly before putting in or taking out your contact lenses. Make sure to disinfect contact lenses as instructed and replace them as appropriate. Learn more about keeping your eyes healthy while wearing contact lenses and listen to a podcast on keeping your eyes safe.

Practice workplace eye safety. Employers are required to provide a safe work environment. When protective eyewear is required as a part of your job, make a habit of wearing the appropriate type at all times, and encourage your coworkers to do the same.

Eye care and eye safety tips

Your eyes are an important part of your health. Most people rely on their eyes to see and make sense of the world around them. But some eye diseases can lead to vision loss, so it is important to identify and treat eye diseases as early as possible. You should get your eyes checked as often as your health care provider recommends it, or if you have any new vision problems. And just as it is important to keep your body healthy, you also need to keep your eyes healthy.

Eye Care Tips

There are things you can do to help keep your eyes healthy and make sure you are seeing your best:

  • Eat a healthy, balanced diet. Your diet should include plenty or fruits and vegetables, especially deep yellow and green leafy vegetables. Eating fish high in omega-3 fatty acids, such as salmon, tuna, and halibut can also help your eyes.
  • Maintain a healthy weight. Being overweight or having obesity increases your risk of developing diabetes. Having diabetes puts you at higher risk of getting diabetic retinopathy or glaucoma.
  • Get regular exercise. Exercise may help to prevent or control diabetes, high blood pressure, and high cholesterol. These diseases can lead to some eye or vision problems. So if you exercise regularly, you can lower your risk of getting these eye and vision problems.
  • Wear sunglasses. Sun exposure can damage your eyes and raise your risk of cataracts and age-related macular degeneration. Protect your eyes by using sunglasses that block out 99 to 100% of both UV-A and UV-B radiation.
  • Wear protective eye wear. To prevent eye injuries, you need eye protection when playing certain sports, working in jobs such as factory work and construction, and doing repairs or projects in your home.
  • Avoid smoking. Smoking increases the risk of developing age-related eye diseases such as macular degeneration and cataracts and can damage the optic nerve.
  • Know your family medical history. Some eye diseases are inherited, so it is important to find out whether anyone in your family has had them. This can help you determine if you are at higher risk of developing an eye disease.
  • Know your other risk factors. As you get older, you are at higher risk of developing age-related eye diseases and conditions. It is important to know you risk factors because you may be able to lower your risk by changing some behaviors.
  • If you wear contacts, take steps to prevent eye infections. Wash your hands well before you put in or take out your contact lenses. Also follow the instructions on how to properly clean them, and replace them when needed.
  • Give your eyes a rest. If you spend a lot of time using a computer, you can forget to blink your eyes and your eyes can get tired. To reduce eyestrain, try the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds.

Eye Tests and Exams

Everyone needs to have their eyesight tested to check for vision and eye problems. Children usually have vision screening in school or at their health care provider’s office during a checkup. Adults may also get vision screenings during their checkups. But many adults need more than a vision screening. They need a comprehensive dilated eye exam.

Getting comprehensive dilated eye exams is especially important because some eye diseases may not have warning signs. The exams are the only way to detect these diseases in their early stages, when they are easier to treat.

The exam includes several tests:

  • A visual field test to measure your side (peripheral) vision. A loss of peripheral vision may be a sign of glaucoma.
  • A visual acuity test, where you read an eye chart about 20 feet away, to check on how well you see at various distances
  • Tonometry, which measures your eye’s interior pressure. It helps to detect glaucoma.
  • Dilation, which involves getting eye drops that dilate (widen) your pupils. This allows more light to enter the eye. Your eye care provider examines your eyes using a special magnifying lens. This provides a clear view of important tissues at the back of your eye, including the retina, macula, and optic nerve.

If you have a refractive error and are going to need glasses or contacts, then you will also have a refraction test. When you have this test, you look through a device that has lenses of different strengths to help your eye care professional figure out which lenses will give you the clearest vision.

At what age you should start getting these exams and how often you need them depends on many factors. They include your age, race, and overall health. For example, if you are African American, you are at higher risk of glaucoma and you need to start getting the exams earlier. If you have diabetes, you should get an exam every year. Check with your health care provider about if and when you need these exams

Contact lenses -Eye/Optical clinic near Obawole Fagba Iju Ishaga

Contact lenses are an excellent choice for nearly anyone who needs vision correction and doesn’t want to wear eyeglasses full time or undergo LASIK surgery.

Unsure about contact lenses? This article will detail contact lens materials, contact lens designs and features and even new contact lens formats.

For instance, the first light-adaptive contact lenses, Acuvue Oasys with Transitions, debuted in the United States in 2019 and contact lenses embedded with antibiotics are in the works. (See our contact lens news page for the latest in contact lenses.)

Here are the basics you should know about contact lenses before seeing your eye doctor if you are interested in wearing contacts.

Contact Lens Materials

The first choice when considering contact lenses is which lens material will best satisfy your needs. There are five types of contact lenses, based on type of lens material they are made of:

ExpandableContact Lens Material

  • Soft lenses are made from gel-like, water-containing plastics called hydrogels. These lenses are very thin and pliable and conform to the front surface of the eye. Introduced in the early 1970s, hydrogel lenses made contact lens wear much more popular because they typically are immediately comfortable. The only alternative at the time was hard contact lenses made of PMMA plastic (see below). PMMA lenses typically took weeks to adapt to and many people couldn’t wear them successfully.
  • Silicone hydrogel lenses are an advanced type of soft contact lenses that are more porous than regular hydrogel lenses and allow even more oxygen to reach the cornea. Introduced in 2002, silicone hydrogel contact lenses are now the most popular lenses prescribed in the United States.
  • Gas permeable lenses — also called GP or RGP lenses — are rigid contact lenses that look and feel like PMMA lenses (see below) but are porous and allow oxygen to pass through them. Because they are permeable to oxygen, GP lenses can be fit closer to the eye than PMMA lenses, making them more comfortable than conventional hard lenses. Since their introduction in 1978, gas permeable contact lenses have essentially replaced nonporous PMMA contact lenses. GP contacts often provide sharper vision than soft and silicone hydrogel contacts — especially if you have astigmatism. It usually takes some time for your eyes to adjust to gas permeable lenses when you first start wearing them, but after this initial adaptation period, most people find GP lenses are as comfortable as hydrogel lenses.
  • Hybrid contact lenses are designed to provide wearing comfort that rivals soft or silicone hydrogel lenses, combined with the crystal-clear optics of gas permeable lenses. Hybrid lenses have a rigid gas permeable central zone, surrounded by a “skirt” of hydrogel or silicone hydrogel material.

Contact lens basics: Types of contact lenses and more

By Liz Segre

Contact lenses are an excellent choice for nearly anyone who needs vision correction and doesn’t want to wear eyeglasses full time or undergo LASIK surgery.

Unsure about contact lenses? This article will detail contact lens materials, contact lens designs and features and even new contact lens formats.

For instance, the first light-adaptive contact lenses, Acuvue Oasys with Transitions, debuted in the United States in 2019 and contact lenses embedded with antibiotics are in the works. (See our contact lens news page for the latest in contact lenses.)

Here are the basics you should know about contact lenses before seeing your eye doctor if you are interested in wearing contacts.

Contact Lens Materials

The first choice when considering contact lenses is which lens material will best satisfy your needs. There are five types of contact lenses, based on type of lens material they are made of:

ExpandableContact Lens Material

  • Soft lenses are made from gel-like, water-containing plastics called hydrogels. These lenses are very thin and pliable and conform to the front surface of the eye. Introduced in the early 1970s, hydrogel lenses made contact lens wear much more popular because they typically are immediately comfortable. The only alternative at the time was hard contact lenses made of PMMA plastic (see below). PMMA lenses typically took weeks to adapt to and many people couldn’t wear them successfully.
  • Silicone hydrogel lenses are an advanced type of soft contact lenses that are more porous than regular hydrogel lenses and allow even more oxygen to reach the cornea. Introduced in 2002, silicone hydrogel contact lenses are now the most popular lenses prescribed in the United States.
  • Gas permeable lenses — also called GP or RGP lenses — are rigid contact lenses that look and feel like PMMA lenses (see below) but are porous and allow oxygen to pass through them. Because they are permeable to oxygen, GP lenses can be fit closer to the eye than PMMA lenses, making them more comfortable than conventional hard lenses. Since their introduction in 1978, gas permeable contact lenses have essentially replaced nonporous PMMA contact lenses. GP contacts often provide sharper vision than soft and silicone hydrogel contacts — especially if you have astigmatism. It usually takes some time for your eyes to adjust to gas permeable lenses when you first start wearing them, but after this initial adaptation period, most people find GP lenses are as comfortable as hydrogel lenses.
  • Hybrid contact lenses are designed to provide wearing comfort that rivals soft or silicone hydrogel lenses, combined with the crystal-clear optics of gas permeable lenses. Hybrid lenses have a rigid gas permeable central zone, surrounded by a “skirt” of hydrogel or silicone hydrogel material. Despite these features, only a small percentage of people in the U.S. wear hybrid contact lenses, perhaps because these lenses are more difficult to fit and are more expensive to replace than soft and silicone hydrogel lenses.
  • PMMA lenses are made from a transparent rigid plastic material called polymethyl methacrylate (PMMA), which also is used as a substitute for glass in shatterproof windows and is sold under the trademarks Lucite, Perspex and Plexiglas. PMMA lenses have excellent optics, but they do not transmit oxygen to the eye and can be difficult to adapt to. These (now old-fashioned) “hard contacts” have virtually been replaced by GP lenses and are rarely prescribed today.

In 2017, 64 percent of contact lenses prescribed in the U.S. were silicone hydrogel lenses, followed by soft (hydrogel) lenses (22 percent), gas permeable lenses (11 percent), hybrid lenses (2 percent) and PMMA lenses (1 percent).

Contact Lens Wearing Time

Until 1979, everyone who wore contact lenses removed and cleaned them nightly. The introduction of “extended wear” enabled wearers to sleep in their contacts. Now, two types of lenses are classified by wearing time:

  • Daily wear — must be removed nightly
  • Extended wear — can be worn overnight, usually for seven days consecutively without removal

“Continuous wear” is a term that’s sometimes used to describe 30 consecutive nights of lens wear — the maximum wearing time approved by the FDA for certain brands of extended wear lenses

When To Replace Your Contact Lenses

Even with proper care, contact lenses (especially soft contacts) should be replaced frequently to prevent the build-up of lens deposits and contamination that increase the risk of eye infections.

Soft lenses have these general classifications, based on how frequently they should be discarded:

ExpandableLens Replacement Frequency

  • Daily disposable lenses — Discard after a single day of wear
  • Disposable lenses — Discard every two weeks, or sooner
  • Frequent replacement lenses — Discard monthly or quarterly
  • Traditional (reusable) lenses — Discard every six months or longer

Gas permeable contact lenses are more resistant to lens deposits and don’t need to be discarded as frequently as soft lenses. Often, GP lenses can last a year or longer before they need to be replaced.

The most frequently prescribed contact lens replacement schedule in the U.S. in 2017 was monthly (40 percent), followed by daily (35 percent), every one to two weeks (24 percent) and annually (1 percent).

Contact Lens Designs

Soft contact lenses (both standard hydrogel and silicone hydrogel lenses) are available in a variety of designs, depending on their intended purpose:

ExpandableSoft contact lens designs

  • Spherical contact lenses have the same lens power throughout the entire optical part of the lens to correct myopia (nearsightedness) or hyperopia (farsightedness).
  • Toric soft contact lenses have different powers in different meridians of the lens to correct astigmatism as well as nearsightedness or farsightedness. [Read more about toric contact lenses.]
  • Multifocal contact lenses (including bifocal contacts) contain different power zones for near and far vision to correct presbyopia as well as nearsightedness or farsightedness. Some multifocal lenses also can correct astigmatism. [Read more about bifocal contacts.]
  • Cosmetic contact lenses include color contacts designed to change or intensify your eye color. Halloween, theatrical and other special-effect contacts also are considered cosmetic lenses. A contact lens prescription is required for cosmetic contacts even if you have no refractive errors that need correction.

All of these lenses can be custom made for hard-to-fit eyes. Other lens designs also are available — including lenses fabricated for use in special situations, such as correcting for keratoconus.

More Contact Lens Features

Bifocal contacts for astigmatism. These are advanced soft contacts that correct both presbyopia and astigmatism, so you can remain glasses-free after age 40 even if you have astigmatism. [More about bifocal contact lenses for astigmatism.]

Contacts for dry eyes. Are your contacts uncomfortably dry? Certain soft contact lenses are specially made to reduce the risk of contact lens-related dry eye symptoms. [More about contact lenses for dry eyes.]

Colored lenses. Many of the types of lenses described above also come in colors that can enhance the natural color of your eyes — that is, make your green eyes even greener, for example. Other colored lenses can totally change the color of your eyes, as in from brown to blue.

Special-effect lenses. Also called theatrical, novelty, or costume lenses, special-effect contacts take coloration one step further to make you look like a cat, a vampire, or another alter-ego of your choice.

Prosthetic lenses. Colored contact lenses also can be used for more medically oriented purposes. Opaque soft lenses called prosthetic contacts can be custom-designed for an eye that has been disfigured by injury or disease to mask the disfigurement and match the appearance of the other, unaffected eye.

Custom lenses. If conventional contact lenses don’t seem to work for you, you might be a candidate for custom contact lenses that are made-to-order for your individual eye shape and visual needs.

UV-inhibiting lenses. Some soft contact lenses help protect your eyes from the sun’s ultraviolet rays that can cause cataracts and other eye problems. But because contacts don’t cover your entire eye, you still should wear UV-blocking sunglasses outdoors for the best protection from the sun.

Scleral lenses. Large-diameter gas permeable lenses called scleral contacts are specially designed to treat keratoconus and other corneal irregularities, as well as presbyopia.

Myopia control contacts. Special contact lenses are being developed to slow or stop the progression of nearsightedness in children. [More about myopia control.]

Which Contact Lens Is Right for You?

First, your contacts must address the problem that is prompting you to wear lenses in the first place. Your contact lenses must provide good vision by correcting your myopia, hyperopia, astigmatism, or some combination of those vision problems.

Second, the lens must fit your eye. To do that, lenses come in tens of thousands of combinations of diameter and curvature. Of course, not every lens brand comes in every “size.”

Your ECP is skilled in evaluating your eye’s physiology, and your eyesight, to determine which lens best satisfies the two criteria above.

Third, you may have another medical need that drives the choice of lens. For example, your ECP might pick a particular lens if your eyes tend to be dry.

Finally, consider your “wish list” of contact lens features — colors, for example, or overnight wear.

When you and your ECP decide on the right lens for you, you’ll be given a contact lens prescription. You’ll be able to buy a supply of lenses from your ECP or from the many other outlets that sell contact lenses. [For more on this, please read “Where’s the Best Place to Buy Contact Lenses?”]

Contact Lens Wear and Care

Caring for your contact lenses — cleaning, disinfecting and storing them — is much easier than it used to be.

A few years ago, you would have needed several bottles of cleaning products, and perhaps enzyme tablets, for proper care. Today, most people can use “multipurpose” solutions — meaning that one product both cleans and disinfects, and is used for storage.

People who are sensitive to the preservatives in multipurpose solutions might need preservative-free systems, such as those containing hydrogen peroxide. These do an excellent job of cleaning contacts, but it’s very important to follow the directions for using them. The solution should not come into contact with your eyes until soaking is complete and the solution is neutralized.

Of course, you can avoid lens care altogether by wearing daily disposable contact lenses.

Contact Lens Problems

Trial and error often is involved in finding the perfect lens for you. People react differently to various lens materials and cleaning solutions.

Also, the correct “parameters” of your lens — that is, power, diameter, and curvature — can be finalized only after you’ve successfully worn the lens. This is especially true for more complex fits involving extra parameters, such as with bifocals or toric contact lenses for astigmatism.

If you experience discomfort or poor vision when wearing contact lenses, chances are that an adjustment or change of lens can help.

Today, more contact lens choices than ever are available to provide comfort, good vision, and healthy eyes. If your eyes or lenses are uncomfortable or you are not seeing well, remove your lenses and visit your eye care professional to explore available remedies for contact lens discomfort.

Buying Contact Lenses

You can buy replacement contact lenses at many places, and some offer a better value than others. Find out more about where to buy contacts and buying contact lenses online.

Eye care tips – Eye/Optical clinic near Obawole Fagba Iju Ishaga

Your eyes are an important part of your health. Most people rely on their eyes to see and make sense of the world around them. But some eye diseases can lead to vision loss, so it is important to identify and treat eye diseases as early as possible. You should get your eyes checked as often as your health care provider recommends it, or if you have any new vision problems. And just as it is important to keep your body healthy, you also need to keep your eyes healthy.

Eye Care Tips

There are things you can do to help keep your eyes healthy and make sure you are seeing your best:

  • Eat a healthy, balanced diet. Your diet should include plenty or fruits and vegetables, especially deep yellow and green leafy vegetables. Eating fish high in omega-3 fatty acids, such as salmon, tuna, and halibut can also help your eyes.
  • Maintain a healthy weight. Being overweight or having obesity increases your risk of developing diabetes. Having diabetes puts you at higher risk of getting diabetic retinopathy or glaucoma.
  • Get regular exercise. Exercise may help to prevent or control diabetes, high blood pressure, and high cholesterol. These diseases can lead to some eye or vision problems. So if you exercise regularly, you can lower your risk of getting these eye and vision problems.
  • Wear Transition lenses. Sun exposure can damage your eyes and raise your risk of cataracts and age-related macular degeneration. Protect your eyes by using sunglasses that block out 99 to 100 percent of both UV-A and UV-B radiation.
  • Wear protective eye wear. To prevent eye injuries, you need eye protection when playing certain sports, working in jobs such as factory work and construction, and doing repairs or projects in your home.
  • Avoid smoking. Smoking increases the risk of developing age-related eye diseases such as macular degeneration and cataracts and can damage the optic nerve.
  • Know your family medical history. Some eye diseases are inherited, so it is important to find out whether anyone in your family has had them. This can help you determine if you are at higher risk of developing an eye disease.
  • Know your other risk factors. As you get older, you are at higher risk of developing age-related eye diseases and conditions. It is important to know you risk factors because you may be able to lower your risk by changing some behaviors.
  • If you wear contacts, take steps to prevent eye infections. Wash your hands well before you put in or take out your contact lenses. Also follow the instructions on how to properly clean them, and replace them when needed.
  • Give your eyes a rest. If you spend a lot of time using a computer, you can forget to blink your eyes and your eyes can get tired. To reduce eyestrain, try the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds.

Eye Tests and Exams

Everyone needs to have their eyesight tested to check for vision and eye problems. Children usually have vision screening in school or at their health care provider’s office during a checkup. Adults may also get vision screenings during their checkups. But many adults need more than a vision screening. They need a comprehensive dilated eye exam.

Getting comprehensive dilated eye exams is especially important because some eye diseases may not have warning signs. The exams are the only way to detect these diseases in their early stages, when they are easier to treat.

The exam includes several tests:

  • A visual field test to measure your side (peripheral) vision. A loss of peripheral vision may be a sign of glaucoma.
  • A visual acuity test, where you read an eye chart about 20 feet away, to check on how well you see at various distances
  • Tonometry, which measures your eye’s interior pressure. It helps to detect glaucoma.
  • Dilation, which involves getting eye drops that dilate (widen) your pupils. This allows more light to enter the eye. Your eye care provider examines your eyes using a special magnifying lens. This provides a clear view of important tissues at the back of your eye, including the retina, macula, and optic nerve.

If you have a refractive error and are going to need glasses or contacts, then you will also have a refraction test. When you have this test, you look through a device that has lenses of different strengths to help your eye care professional figure out which lenses will give you the clearest vision.

At what age you should start getting these exams and how often you need them depends on many factors. They include your age, race, and overall health. For example, if you are African American, you are at higher risk of glaucoma and you need to start getting the exams earlier. If you have diabetes, you should get an exam every year. Check with your health care provider about if and when you need these exams

Eye test – Eye clinic within Obawole Iju Ishagah Fagba

Dr. Dr. Steven E.N., Eyeupdate clinic & optical supplies, 01 Ajuwon junction, beside BPNL filling station, Ajuwon, off Elliot bus stop, Iju-Ishagah, Lagos. Tel: 08107531046, 08034971582.

 

Eye exam/test consists of series of tests that your eye doctor will perform in order to determine your ocular status.

An eye exam involves a series of tests to evaluate your vision and check for eye diseases/vision defects. Your eye doctor may use a variety of instruments, shine bright lights directly at your eyes and request that you look through an array of lenses. Each test during an eye exam evaluates a different aspect of your vision or eye health.

Why it’s done

An eye exam helps detect eye problems at their earliest stage — when they’re most treatable. Regular eye exams give your eye care professional a chance to help you correct or adapt to vision changes and provide you with tips on caring for your eyes.

When to have an eye exam

Several factors may determine how frequently you need an eye exam, including your age, health and risk of developing eye problems. General guidelines are as follows:

Children 3 years and younger

For children under 3, your pediatrician will likely look for the most common eye problems — lazy eye, crossed eyes or misaligned eyes. If there are eye concerns or symptoms, an examination is appropriate at that time regardless of age. Your child could undergo a more comprehensive eye exam between the ages of 3 and 5.

School-age children and adolescents

Have your child’s vision checked before he or she enters first grade. If your child has no symptoms of vision problems and no family history of vision problems, have his or her vision rechecked every one to two years. Otherwise, schedule eye exams based on the advice of your eye doctor.

Adults

In general, if you are healthy and you have no symptoms of vision problems, have your eyes checked on this schedule:

  • Every five to 10 years in your 20s and 30s
  • Every two to four years from 40 to 54
  • Every one to three years from 55 to 64
  • Every one to two years after age 65

Have your eyes checked more often if you:

  • Wear glasses or contact lenses
  • Have a family history of eye disease or loss of vision
  • Have a chronic disease that puts you at greater risk of eye disease, such as diabetes
  • Take medications that have serious eye side effects

  • How you prepare

    There are three different types of eye specialists. Which specialist you choose may be a matter of personal preference or will depend on the nature of your eye problem.

    • Ophthalmologists. Ophthalmologists are medical doctors who provide full eye care, such as giving you a complete eye exam, prescribing corrective lenses, diagnosing and treating complex eye diseases, and performing eye surgery.
    • Optometrists. Optometrists provide many of the same services as ophthalmologists, such as evaluating your vision, prescribing corrective lenses, diagnosing common eye disorders and treating selected eye diseases with drugs. If you have a complex eye problem or need surgery, your doctor can refer you to an ophthalmologist.
    • Opticians. Opticians fill prescriptions for eyeglasses, including assembling, fitting and selling them. Some opticians also sell contact lenses. Opticians do not provide eye health evaluations.

    Bring your prescription eyewear

    If you wear contact lenses or glasses, bring them to your appointment. Your eye doctor will want to make sure your prescription is the best one for you.

    Other precautions

    If your eyes are dilated as a part of your eye exam, you may want to bring sunglasses to wear after your eye exam is complete, as daylight or other bright lights may be uncomfortable or cause blurred vision. Also, consider having someone else drive you home.

    What you can expect

    Before the exam

    If you’re seeing a new eye doctor or if you’re having your first eye exam, expect questions about your vision history. Part of the examination, such as taking your medical history and the initial eye test, may be performed by a clinical assistant or technician.

    Your answers help your eye doctor understand your risk of eye disease and vision problems. Be prepared to give specific information, including:

    • Are you having any eye problems now?
    • Have you had any eye problems in the past?
    • Do you wear glasses or contacts now? If so, are you satisfied with them?
    • What health problems have you had in recent years?
    • Were you born prematurely?
    • Are you taking any medications?
    • Do you have any allergies to medications, food or other substances?
    • Have you ever had eye surgery?
    • Does anyone in your family have eye problems, such as macular degeneration, glaucoma or retinal detachments?
    • Do you or does anyone in your family have diabetes, high blood pressure, heart disease or any other health problems that can affect the whole body?

    During the exam

    An eye exam usually involves these steps:

    • You’ll be asked about your medical history and any vision problems you might be experiencing.
    • Your eye doctor measures your visual acuity to see if you need glasses or contact lenses to improve your vision.
    • You’ll be given a numbing drop in your eyes. Then your eye pressure is measured. To make it easier for your doctor to examine the inside of your eye, he or she will likely dilate your eyes with eyedrops.
    • After waiting for the dilating drops to take effect, your eye doctor checks the health of your eyes, possibly using several lights to evaluate the front of the eye and the inside of each eye.

    Several different tests may be performed during the eye exam. The tests are designed to check your vision and to examine the appearance and function of all parts of your eyes.

    After the exam

    At the end of your eye exam, you and your doctor will discuss the results of all testing, including an assessment of your vision, your risk of eye disease and preventive measures you can take to protect your eyesight.

    Different types of eye exams

    Eye muscle test

    This test evaluates the muscles that control eye movement. Your eye doctor watches your eye movements as you follow a moving object, such as a pen or small light, with your eyes. He or she looks for muscle weakness, poor control or poor coordination.

    Visual acuity test

    This test measures how clearly you see. Your doctor asks you to identify different letters of the alphabet printed on a chart (Snellen chart) or a screen positioned some distance away. The lines of type get smaller as you move down the chart. Each eye is tested separately. Your near vision also may be tested, using a card with letters similar to the distant eye chart. The card is held at reading distance.

    Refraction assessment

    Light waves are bent as they pass through your cornea and lens. If light rays don’t focus perfectly on the back of your eye, you have a refractive error. Having a refractive error may mean you need some form of correction, such as glasses, contact lenses or refractive surgery, to see as clearly as possible.

    Assessment of your refractive error helps your doctor determine a lens prescription that will give you the sharpest, most comfortable vision. The assessment may also determine that you don’t need corrective lenses.

    Your doctor may use a computerized refractor to estimate your prescription for glasses or contact lenses. Or he or she may use a technique called retinoscopy. In this procedure, the doctor shines a light into your eye and measures the refractive error by evaluating the movement of the light reflected by your retina back through your pupil.

    Your eye doctor usually fine-tunes this refraction assessment by having you look through a masklike device that contains wheels of different lenses (phoropter). He or she asks you to judge which combination of lenses gives you the sharpest vision.

    Visual field test (perimetry)

    Your visual field is the full extent of what you can see to the sides without moving your eyes. The visual field test determines whether you have difficulty seeing in any areas of your overall field of vision. The different types of visual field tests include:

    • Confrontation exam. Your eye doctor sits directly in front of you and asks you to cover one eye. You look straight ahead and tell the doctor each time you see his or her hand move into view.
    • Manual testing, including tangent screen and Goldmann exams. You sit a short distance from a screen and focus on a target at its center. You tell the doctor when you can see an object move into your peripheral vision and when it disappears.
    • Automated perimetry. As you look at a screen with blinking lights on it, you press a button each time you see a blink.

    Using your responses to one or more of these tests, your eye doctor determines the fullness of your field of vision. If you aren’t able to see in certain areas, noting the pattern of your visual field loss may help your eye doctor diagnose your eye condition.

    Color vision testing

    You could have poor color vision and not even realize it. If you have difficulty distinguishing certain colors, your eye doctor may screen your vision for a color deficiency. To do this, your doctor shows you several multicolored dot-pattern tests.

    If you have no color deficiency, you’ll be able to pick out numbers and shapes from within the dot patterns. If you do have a color deficiency, you’ll find it difficult to see certain patterns within the dots. Your doctor may use other tests, as well.

    Slit-lamp examination

    A slit lamp is a microscope that magnifies and illuminates the front of your eye with an intense line of light. Your doctor uses this device to examine the eyelids, lashes, cornea, iris, lens and fluid chamber between your cornea and iris.

    Your doctor may use a dye, most commonly fluorescein (flooh-RES-een), to color the film of tears over your eye. This helps reveal any damaged cells on the front of your eye. Your tears wash the dye from the surface of your eye fairly quickly.

    Retinal examination

    A retinal examination — sometimes called ophthalmoscopy or funduscopy — allows your doctor to evaluate the back of your eye, including the retina, the optic disk and the underlying layer of blood vessels that nourish the retina (choroid). Usually before your doctor can see these structures, your pupils must be dilated with eyedrops that keep the pupil from getting smaller when your doctor shines light into the eye.

    After administering eyedrops and giving them time to work, your eye doctor may use one or more of these techniques to view the back of your eye:

    • Direct exam. Your eye doctor uses an ophthalmoscope to shine a beam of light through your pupil to see the back of the eye. Sometimes eyedrops aren’t necessary to dilate your eyes before this exam.
    • Indirect exam. During this exam, you might lie down, recline in a chair or sit up. Your eye doctor examines the inside of the eye with the aid of a condensing lens and a bright light mounted on his or her forehead. This exam lets your doctor see the retina and other structures inside your eye in great detail and in three dimensions.

    Screening for glaucoma

    Tonometry measures the fluid pressure inside your eye (intraocular pressure). This is one test that helps your eye doctor detect glaucoma, a disease that damages the optic nerve.

    Several methods to measure intraocular pressure are available, including:

    • Applanation tonometry. This test measures the amount of force needed to temporarily flatten a part of your cornea. You’ll be given eyedrops with fluorescein, the same dye used in a regular slit-lamp examination. You’ll also receive eyedrops containing an anesthetic. Using the slit lamp, your doctor moves the tonometer to touch your cornea and determine the eye pressure. Because your eye is numbed, the test doesn’t hurt.
    • Noncontact tonometry. This method uses a puff of air to estimate the pressure in your eye. No instruments touch your eye, so you won’t need an anesthetic. You’ll feel a momentary pulse of air on your eye, which can be startling.

    If your eye pressure is higher than average or your optic nerve looks unusual, your doctor may use a pachometer. This instrument uses sound waves to measure the thickness of your cornea. The most common way of measuring corneal thickness is to put an anesthetic drop in your eye, then place a small probe in contact with the front surface of the eye. The measurement takes seconds.

    You may need more-specialized tests, depending on your age, medical history and risk of developing eye disease.

    Results

    Normal results from an eye exam include:

    • 20/20 vision
    • Good peripheral vision
    • Ability to distinguish various colors
    • Normal-appearing structures of the external eye
    • Absence of cataract, glaucoma or retinal disorders, such as macular degeneration

    Your doctor may give you a prescription for corrective lenses. If your eye exam yields other abnormal results, your doctor will discuss with you next steps for further testing or for treating an underlying condition.
