What An Eye Test Can Detect

According to a 2010 survey by Mintel, 1 in 5 adults admit to either rarely having an eye test or never having one at all. For many people an eye test can be a distraction; if you don’t think you need glasses then why bother going to see an optician? However, this doesn’t tell the full story and an eye test can reveal much more about your health than just your eyesight.

An eye test can detect a range of poor health conditions including diabetes

Far from simply assessing your need for glasses, an eye test can detect conditions such as diabetes. Around three quarters of a million people in the UK are currently suffering from diabetes and do not even know it and the condition can prove to be life threatening if it is not treated with proper medication and a healthy diet.

A simple eye test can detect the signs of diabetes; over time the condition weakens the tiny blood vessels which are close to the retina and this can be picked up by an optician. Most people are very surprised what an eye test can detect.

An eye test can detect high blood pressure

Aside from diabetes, high blood pressure is another major ailment that can be detected through a quick trip to have your eyes tested. Indeed, this actually applies greatly to younger people who haven’t had any blood pressure checks.

While we associated the condition with old age many people in their twenties are starting to develop high blood pressure and it is unlikely that they will get checked for it by their GP. Through an eye test an optician can see the signs of high blood pressure through blood vessels in the retina and in many cases it has saved peoples’ lives.

An eye test can detect glaucoma

Perhaps one of the biggest conditions detected by an eye test is glaucoma. A common problem that can eventual lead to blindness if not treated correctly it can be easily spotted by an eye test check-up even though in its early stages it shows no real symptoms so often goes untreated and unnoticed for years.

An eye test can detect macular degeneration

Lastly we have macular degeneration, a serious condition that an eye test can spot and lead to earlier treatment. The condition generally affects older people and it is categorised by wet and dry types. Although there is no effective treatment for the dry type of macular degeneration an early diagnosis can help you adapt quicker to the problem and the wet type can be treated through laser surgery or medication.

This is not an exhaustive list of conditions and diseases that can be picked up by an eye test but rather it is to highlight some of the more serious medical problems that can be easily identified. Although rare, brain tumours and even cancer can all be seen in their early stages by an optician’s examination and it goes far beyond just inspecting you for new glasses.

How often should you have an eye check?

A good guideline to follow is to have an eye check-up once every 2 years or once per year if you are under 16, over 70 or suffer from diabetes. The process is simple and straightforward and could potentially do much more for you than just prescribing new lenses.

Tips For Contact Lens Wearers

Is My Contact Lens Inside Out?

A question many newbie wearers have is: “How can I tell if my contact lens is inside-out?”

The difference can be subtle, but before placing a contact lens on your eye, make sure it looks like half a ball, not a soup bowl with a rim.

The trick is to place the lens on your finger so that a cup is formed. Then hold the lens up directly in front of your eyes so you’re looking at the side of the cup.

If the lens forms a “U” with the top edges flared out, it’s inside out. If it forms just a “U,” it’s in the correct position.

If you’re wearing lenses with a handling tint, another way is to place the lens on your fingertip and then look down at it. The edge of a tinted lens should look very blue (or green, depending on the tint); that won’t be the case if the lens is inverted.

Some contact lenses also have a laser marking, such as the brand name, on the edge to help you. If you can read it properly, the lens is not inside out.

Don’t worry if you place a contact lens in your eye inside out. The lens will feel uncomfortable, but it can’t do any damage.

Applying Your Contact Lenses

Make sure you wash your hands thoroughly before applying your contact lenses, but avoid scented or oily soaps that might adhere to the lens surface. Especially avoid using products containing lanolin and moisturizing lotions.

Some eye doctors say to always apply the first contact lens in the same eye, so you’ll avoid the possibility of mixing up lenses for the right eye and left eye.

Other basic guidelines for contact lens application include:

  • Gently shake your lens case containing the storage solution, to loosen the contact lens should it be stuck. (Don’t try pulling at the lens with your finger, or you might damage it.)
  • Slide the lens out of its case and into the palm of your hand. Rinse thoroughly with the appropriate contact lens solution.
  • Place the contact lens on the tip of your index or middle finger, which should be dry or mostly dry.
  • With the fingers and thumb of your other hand, simultaneously pull up on your upper eyelid and down on your lower eyelid.
  • Position the lens on your eye while looking upward or forward, whichever you find to be easier. You also can apply the contact lens by placing it on the white of the eye closest to your ear.
  • Gently close your eye, roll your eyes in a complete circle to help the lens settle, and then blink.
  • Look closely in the mirror to make sure the lens is centered on your eye. If it is, the lens should be comfortable and your vision should be clear.

Removing Your Contact Lenses

Always wash your hands before removing contact lenses. If you are standing in front of a sink, use a clean paper towel to cover the drain where the contact lens might accidentally fall.

To remove soft contact lenses, look upward or sideways while you pull down on your lower eyelid. With a finger, gently maneuver the lens onto the white of your eye. There, you can very gently pinch the lens together with your index finger and thumb and lift it off the eye.

Until you master contact lens removal, you might want to keep your fingernails short to avoid accidentally scratching and damaging your eye.

Gas permeable contact lenses can be removed by holding out the palm of your hand, bending over, and then opening your eye wide. With one finger of your other hand, pull the skin between your upper and lower eyelid (just outside the lateral aspect of your eye) outward toward your ear with your eye wide open. Then blink. The contact lens should pop right out and into your open palm.

Devices for removing contact lenses, called “plungers,” also are available from your eye doctor, and can be used to touch and directly remove a lens from your eye. Just make sure you touch only the lens and not your eye’s surface with these devices.

While you might hear a myth or two about someone “losing” a contact lens in the back of the eye, this is actually impossible because of a membrane that connects your eye to the back of your eyelid.

Contact Lenses And UV Light

Researchers have linked ultraviolet (UV) light to the formation of cataracts. Exposure to excessive UV light also may result in a condition called photokeratitis.

That’s why some contact lenses now contain a UV-blocking agent. You can’t tell if a contact lens has a UV blocker just by looking at it — the blocking agent is clear, so as not to disturb vision. The contact lens packaging will specify if the product has a UV blocker, or you can ask your eye doctor.

Very important: UV-blocking contacts are not meant to replace sunglasses. A contact lens covers only your cornea, not your entire eye.

However, UV-blocking contact lenses do help protect the portion of the white of your eye that is covered from formation of growths such as pingueculae and pterygia.

Sunglasses with UV protection can cover more of your eye and the parts of your face that surround the eye, depending on the size of the sunglass lens. That’s why contacts with UV blockers are designed to complement sunglass use as an added protection.

Contact Lens Safety Tips

  • DO make sure contact lenses and lens storage cases are cleaned and disinfected regularly, according to your eye doctor’s instructions.
  • DON’T place contact lenses in your mouth or use your saliva to wet them.
  • DO replace contact lenses regularly, according to your eye doctor’s directions.
  • DON’T “top off” old solution in your contact lens case. Instead, discard old solution and replace it with fresh solution.
  • DO always rub contact lenses when you clean them, even if using a “no-rub” solution.

Eye Makeup and Contact Lenses 

Getting makeup in your eye is annoying. But it’s even worse with contacts, because it can stick to the lenses instead of flushing right out. Follow these tips to keep your eyes looking and feeling good:

  • Put your contact lenses on before applying makeup. And always wash your hands thoroughly before touching your contacts, so you won’t transfer any oils, creams or lotions to the lenses.
  • Use only non-allergenic makeup. Almay and Clinique have eye-friendly products, but there are other good brands as well.
  • Cream eye shadow is less likely to get in your eye than powder. But creams can irritate your eyes more if they do make it into your eyes. Choose water-based rather than oil-based creams.
  • If you prefer powder, keep your eyes closed during application. Then, brush off any excess powder before opening your eyes.
  • Never apply eyeliner between your lashes and your eye. Apply eyeliner only on the portion of your lashes that is well away from your eye.
  • To remove eye makeup, wash and dry your hands. Then remove your contacts, being careful not to bump them into any makeup. Finally, use your eye makeup remover.
  • Replace your eye makeup frequently — at least every three months. Don’t use old eye makeup, because over time bacteria will get into the product and then into your eyes, where it can cause an infection. One way to tell if your makeup is too old is if it smells funny. Also, don’t share your eye makeup with others.

Learning About Vision: The Stages Of Development in Children

Childhood Myopia

Infants

Development of the eyes takes place between the first 3-10 weeks in the womb. There after changes will continue to occur much till their adolescence. These stages are interpreted into the following significant changes you should be observing in your child and potential problems to be aware of. The well-being of our vision are of great importance as 80% of our memories are created by what we see in day-to-day life.

Warning signs

  • Child struggles to track objects by 3 months
  • Eyes remain disordered and unable to lock onto objects
  • Eyes appear white

Premature babies may have abnormal replacement of tissue in the retina in serve cases can lead to blindness. Hence, internal eye exams should be made to rule out Retinopathy or Prematurity (ROP), highlighting the importance of immediate incubation after birth.

Complaints about double or blurred vision is also a cause for concern to make a visit to the optometrists, which may also offer referrals to the GP if necessary. Dilation can also be performed in our clinics, this observes the retina and optic nerve to identify any on-going problems particularly used to treat sight loss and various other eye conditions.

Other signs of eye sight problems

  • Sitting to close to the TV or holding a tablet
  • Sensitivity to light
  • Squints when reading
  • Frequently eye rubbing
  • Reports headaches/eye pain

4 months +

In the early 4 months’ baby’s eyesight remains poor as they can only perceive objects 8-10 inches from their face. Hand and eye coordination will begin as they start stacking blocks and track moving objects. Usually minor crossing of the eyes will occur as coordination is yet lacking. Coloured vision is expected to develop at 5 months. You may find as they attempt to examine smaller objects, a cheeky game of hide and seek allows them to build on facial and object recognition.

At 8 months your baby should have clear vision and the ability to calculate distance between objects. Baby’s found to crawl during their growth will have better coordination skills and full 3D interpretation of their surroundings to pick up small objects using their thumb and forefinger. Although in rare cases glasses may be needed.

12 Months +

By 12 months they should be able to tell between near and far. At the two year mark your child should have the capabilities to fully immerse in exploring the environment. Make sure you keep sharp edges especially cabinets away from your child. They also should be encouraged to scribble and draw to create interest in primary colours,visual books cam be helpful in this instance. Colour blindness could also be identified at an early stage, if signs of any struggle to decipher between reds, browns and oranges or blues and purples.

4 Years +

Your child should be able to have an eye test at the age when they are able to decipher their alphabet.  Many schools will start screening at the age of 4+. Usually short-sightedness begins at ages 6+ or earlier as computer and tablet usage in children rises. If you recognise your child to have lazy eye, effective procedure is most successful before the age of 7. Also make sure your child’s eyes are UV protected.

The growth spurt

As eyes continue to develop it becomes increasingly important to have regular eye test, the earlier problems are identified the easier they can be treated. Into adulthood eye sight may deteriorate, frequent monitoring is essential particularly if headaches and eye strain occurs. As many as 1 in 5 children are reported to be short sighted. Take advantage that Children under the ages of 16 or those in education will continue to receive FREE eye test under the NHS.

How to Choose Glasses to Suit Your Face

Choosing glasses to suit your face will make all the difference to your overall look

Did you know that the shape of your face will decide which style of glasses will suit you and also which ones won’t? This handy advice will help you determine which type of glasses compliment your facial features, taking into account your face shape.

Oval

If you have an oval face you are likely to have a round chin and a round forehead. In fact all aspects of your face are in proportion with each other. If you were to look in the mirror your face is likely to give the illusion of being longer with your forehead being a slightly wider width in comparison with your jaw line.

For these reasons wider frames will be your perfect choice, but if you are lucky enough to have an oval face, your face will suit all types of frames. Remember to also take into consideration your hair colour and complexion though.

Rectangular

For those with a rectangular face, you are likely to have a long face with a strong jaw line and square chin. A large square frame will give the appearance of a shorter face and the illusion of a more balanced look. A modern style frame is recommended.

Triangle

Triangular faced people have a broad forehead which tapers down to a narrow chin. A frame that will provide emphasis on the bottom half of your face is required. A frame that is wider at the bottom will help achieve this look. A set of glasses that are rimless, light in colour and material would also work. In other words glasses that are heavy and dark in appearance should be avoided.

Square

Of those that have a square face, you are very likely to also have a strong jaw line accompanied by a broad forehead. A square face is slightly different to a rectangular face because the width and length are in proportion with each other.

The purpose of frames for those with square faces is to soften the angles and ultimately give the appearance of a longer face. A narrow frame will provide depth and will help soften the jaw line and also give the appearance of a longer nose. If you were to consider square shaped frames, you would be gaining the opposite effect and very likely to look out of balance with the rest of your face.

Round

As the name suggests, you have a round face with a round chin and full cheeks. Therefore a frame should make the face appear longer and narrower. The dimensions of your face may be similar but there are no angles to create definition.

A pair of frames that give the illusion of a long face will draw emphasis to the eyes and provide definition to your face. If you’re not sure what face shape you are or which frames will suit you call into Chapman Opticians and one of our qualified staff will talk you through your best options. And of course the surest way to see what suits you is to try the glasses on. So now you know how to choose glasses to suit your face.

How Does UV Light Affect Eyesight?

UV radiation, whether from natural sunlight or artificial UV rays, can seriously damage your eyes.

Most people probably understand the link between ultraviolet (UV) radiation and skin cancer. But many are less aware of the connection between UV radiation and eye damage.

With increased levels of UV radiation reaching the Earth’s surface, it is important to take the necessary precautions to protect your eyes.

What Is UV Light?

The sun’s primary danger to us comes in the form of UV light or radiation. UV radiation is a component of solar radiation. Artificial sources like welding machines, tanning beds, and lasers can also give off UV radiation.

There are three types of UV radiation. UV-C is absorbed by the ozone layer and does not present any threat. UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision.

How Does UV Light Affect Eyesight?

Both long- and short-term exposure to UV radiation can harm the eyes, affect vision, and compromise overall eye health. There are several eye diseases and conditions caused or aggravated by exposure to UV radiation, such as:

Macular Degeneration

Macular Degeneration (AMD) is caused by damage to the retina over time and is the leading cause of age-related blindness. Extended exposure to UV light increases your risk of developing macular degeneration.

Cataracts

A cataract is a clouding of the eye’s natural lens — the part of the eye that focuses the light we see. UV light, especially UV-B rays, increases your risk for certain types of cataracts. It is estimated that 10% of all cataract cases are directly attributable to UV exposure.

Pterygium

Often called “surfer’s eye,” pterygium is a pink, non-cancerous growth that forms on the layer of conjunctiva over the white of your eye. UV light from the sun is believed to be a factor in the development of these growths.

Skin Cancer

Skin cancer in and around the eyelids is also linked to prolonged UV exposure.

Photokeratitis. Also known as corneal sunburn or “snow blindness,” photokeratitis is the result of high short-term exposure to UV-B rays. Long hours at the beach or skiing without proper eye protection can cause this problem. It can be very painful and may cause temporary vision loss.

Who Is at Risk?

Everyone (including children) is at risk for eye damage from UV radiation that can lead to vision loss. Any factor that increases the amount of time you spend in the sun will increase your risk. If you answer yes to more than one of these questions, you may be at higher risk of UV radiation damage to your eyes:

  • Do you spend long hours in the sun? (Skiing, mountain climbing, swimming, at the beach, etc.)
  • Do you use a sunlamp, tanning bed or booth?
  • Do you live in the mountains or the US Sunbelt?
  • Have you had cataract surgery (in one or both eyes) or do you have a retinal disorder?
  • Are you on certain medicines, such as tetracycline, sulfa drugs, birth control pills, diuretics and tranquilizers (that increase the eye’s sensitivity to light)?
  • Are you a welder, medical technologist or do you work in the graphic arts or in the manufacturing of electronic circuit boards?

How Can You Protect Your Eyes from UV Light?

Know the dangers. UV rays can come from many directions. They radiate directly from the sun, but they are also reflected from the ground, from water, snow, sand and other bright surfaces.

Wear proper eye protection and hats to block the UV rays. To provide adequate protection for your eyes, sunglasses should:

  • Block out 99 to 100 percent of both UV-A and UV-B radiation
  • Screen out 75 to 90 percent of visible light
  • Be perfectly matched in color and free of distortion and imperfection
  • Have lenses that are gray for proper color recognition

If you spend a lot of time outdoors in bright sunlight, wrap around frames can provide additional protection from the harmful solar radiation. Lastly, don’t forget about protection for your children and teenagers, as they typically spend more time in the sun than adults.
