Melanin lenses in London

Handmade Designer Glasses

Melanin lenses in London. What is melanin and why is it so good at protecting us against the harmful effects of UV radiation?

Melanin is best known as a skin pigment. It gives us different skin complexions depending on the amount of melanin we have. The less melanin we have the paler the complexion and the more we have the darker the complexion.

However, melanin is also made by our bodies in response to UV light. This is known as the familiar tan so many of us crave.

Melanin is found in the eyes and helps protect against the damaging effects of UV radiation. It also helps reduce the effect of glare from stray light in the eyes. 90% of the light that enters the eyes is absorbed by the melanin, allowing us to have better vision.

With age the melanin levels in our eyes fall causing a greater risk to UV damage and also to glare. Some people may also have abnormally low levels of eye melanin that causes poor vision.

Melanin lenses as sunglasses give 100% UV protection and also filter 98% of blue light. They do a better job at UV protection than standard tinted lenses. Why is this? Standard tinted lenses do not protect against HEV which is on the blue end of the spectrum.

Different types of UV light

  1. UVA = wavelengths 320-400 nm. Slightly blocked by the Earth’s ozone layer.
  2. UVB = wavelengths 280-320 nm. Strongly blocked by the Earth’s ozone layer.
  3. UVC = wavelengths  100-280 nm. Very Strongly blocked by the Earth’s ozone layer.
  4. HEV (high energy visible) = 400-500nm. Not blocked by the Earth’s ozone layer.

Melanin lenses and macular degeneration

Macular degeneration is a degenerative condition that affects the aging population and is linked to among other things light damage from free-radicals which are no longer absorbed by naturally occurring antioxidants found in the eye. These antioxidants (Lutein and Zeaxanthin) fall in concentration as we age. Melanin acts as an antioxidant protecting the eyes from harmful free radicals.

Sunglasses with melanin tints give the best protection against free-radicals being produced by the UV and HEV spectrum.

I have been told I have presbyopia

Presbyopia is the medical term for long-sightedness that is associated with age. So what is Presbyopia? Well, it is not a disease, or a condition but more a natural part of the aging process in which the eyes struggle to focus on near objects.

The initial symptoms are problems in changing focus from an object in the distance to a near by object, blurred vision (when viewing close objects), eyestrain after close-up work (especially in dim light) and occasionally double vision and headaches.

At what age does Presbyopia strike?

Presbyopia usually affects people between the ages of 40 and 50. Because it is a slow degenerative symptom, people may go a few years after first noticing the problem and seeking help.

If someone develops presbyopia before the age of 40 then it is referred to as premature presbyopia. Premature presbyopia usually occurs if someone already has hypermetropia (long-sightedness), but it can also occur in people who spend a substantial amount of time involved in close-up work such as reading, sewing or computer work. As ultraviolet exposure can be a factor, those who live in warm climates may be more likely to develop premature presbyopia.

What causes it?

The lens of the eye has to change shape in order to focus on objects of different distances. The natural resting state of the eye allows us to focus on objects in the distance, for this we use long sight. In order for the eye to focus on objects that are closer to us, the lens of the eye must change thickness.

The ciliary muscles of the eye must contract, causing the lens to alter shape. With the lens in a new thicker and more curved shape, the retina is able to bring the light rays from close objects into sharp focus. As we age, the lens of the eye becomes much less elastic and finds it harder to change shape. The ciliary muscles aren’t as strong and supple, and our vision is affected.

What can be done about Presbyopia?

Glasses or contact lenses may be prescribed. If you already wear corrective lenses, then you may find that your prescription has altered and you will need to get a new one. Bifocals or varifocal lenses may be prescribed to allow you to focus on objects that are closer up.

If you wear contact lenses they you may need to start wearing reading glasses too, or to look at different contact lenses such as bifocal or varifocals ones. Your optician can talk you through all of the options, and help you to choose something that works with your lifestyle and budget.

If you do not already wear glasses or contact lenses, then you may need to start wearing glasses for close-up work such as reading. If your optician advises you to wear reading glasses, then it is advisable to ensure that you wear them whenever you do any close-up work to support your eyes and prevent you from having symptoms such as headaches from eye strain. It is also worth being vigilant that you do any close-up work in a well lit environment as poor lighting can cause the symptoms to worsen.

Eyecare Tips

Whether you have no symptoms of presbyopia, the early signs or have noticed a dramatic difference in your near sight due to age; here are some tips to get the best from your vision.

  • Visit your optician regularly to maintain the health of your eyes
  • Take regular breaks when engaging in close-up work, to allow your ocular muscles to relax. Simply look into the distance every ten minutes or so, to achieve this.
  • Wear sunglasses with a high eye protection factor to help prevent UV damage.
  • Eat a healthy balanced diet with plenty of vitamins A, C and E.
  • If you work on the computer for hours a day, then avoid screen glare by keeping lights from shining directly on to the screen. Keep the screen below eye level and as far from you as possible. Speak to your optician about computer glasses which relieve screen glare and take the pressure off eye muscles.

What Causes Blurred Vision in Eyes?

Blurred Vision?

What causes blurred vision in eyes? Blurred vision isn’t something that should be ignored. Whilst tiredness or a common cold could be an occasional cause, regular episodes of blurred vision could be caused by something else, and could lead to more serious problems. We take a look at some of the most common causes of blurred vision and what can be done about them.

Refractive Eye Conditions

Refractive eye conditions are a common cause of blurred vision and include myopia (short sightedness), hyperopia (long sightedness) and astigmatism (where both distances cause a problem). This is easily identified by an eye test and corrected by prescription glasses or contact lenses.

Presbyopia

You may not have heard the term very often but you will certainly be familiar with the condition. Presbyopia is an age related condition typically experienced in your mid 40’s onwards which impairs the eye’s ability to focus on close objects and like the conditions mentioned above, can be helped with glasses or contact lenses.

Dry Eyes

Dry eyes affects many people, and is caused by the eyes inability to produce sufficient moisture for the eye which is essential to protect it. This can be a result of occasional irritations such as the weather, allergies or blocked ducts. Many dry eye problems can be helped with the use of eye drops which can help to keep the eye moisturised and encourage tear production.

Ill Health

Blurred vision can happen as a result of common health problems such as cold and flu, migraines and hayfever. If blurred vision has come on at the same time as other symptoms associated with these conditions, the blurred vision should improve as the other symptoms are treated.

Cataracts

One of the most serious sources of blurred vision is a cataract, which unfortunately, like many other eye conditions, develop as we age. A cataract is essentially the clouding of the lens, which causes blurred vision and an inability to focus. Cataracts can be treated with surgery and many people are able to regain their sight following a successful procedure.

There are of course more serious causes of blurred vision and you should be extra cautious if you develop sudden blurred vision without an obvious cause or other symptoms. If you are concerned at all about blurred vision, Chapman Opticians can help diagnose the cause and provide treatment where needed. Get in touch with one of the team to arrange your appointment.
