The eyes are especially susceptible to the sun because of the transparency of the outer tissues. Long-term exposure can speed up ageing of the macula, the most sensitive part of the retina and can also lead to cataracts. Look for sunglasses that meet the European safety standards. This means they will be of good optical quality with break-resistant lenses, providing high levels of protection against ultraviolet light. One of the key functions of sunglasses is to reduce the amount of sunlight entering the eye. Look for a pair offering a light reduction of up to 80%, that is they will allow in only 20% of the sunlight. The size of the lens - the area shielded - affects light admitted.
- Expensive sometimes means better, but not necessarily. What really counts is the degree to which the lenses filter out harmful UV rays. Look for the CE mark, which proves they conform to the European Community Standard. They should also satisfy British Standard BSEN1836, meaning they will provide high levels of protection against damaging ultraviolet light.
- Do not confuse the shade of the lenses with their ability to filter UV rays. Dark sunglasses may still allow UV rays to enter the eye. Sunglasses are marked with a filter category from 0-4, where 4 is the darkest lens. UV protection has nothing to do with lens colour. The best makes will block 100% of UV-A, UV-B and harmful blue light.
- Polarising lenses will reduce reflective glare from water and land surfaces, making them particularly good at improving vision in bright or hazy driving conditions.
- Anti-reflective coatings eliminate glare.
- Photocromic lenses go darker in the sunlight and are good UV absorbers.
- Impact-resistant lenses are essential for a sporty or active lifestyle as they are made from polycarbonate or toughened glass.
- Wraparound styles further protect the eyes by helping to keep out peripheral glare.

Protect your child's eyes from the sun!
There is evidence that too much exposure to the sun's ultraviolet (UV) rays can contribute to the development of cataracts and age-related macular degeneration. Because children tend to spend a lot of time outdoors, it's important to protect your child's eyes in the sun. Make sure that sunglasses have 100% UV protection and carry the British Standard (BS EN 1836:2005) or CE mark. You can also protect your child's eyes by making sure they wear a hat with a brim or sun visor in bright sunlight.
However, scientific studies have shown that children who spend time outdoors are less likely to be short-sighted, and some eye problems are linked to unhealthy lifestyles. So don't stop your child exercising outdoors - just make sure their eyes are properly protected. |
