Sunglasses are must for eye health
Weekend Plus Desk :
hen you think of sunglasses, fashion may be the first thing to come to mind. You know that they serve a function, but the importance of having and wearing sunglasses every time youâ€™re outside may not be fully clear.
There are some very important reasons that you should wear your sunglasses every time, and weâ€™ll show you why prescription sunglasses are the best way to maintain eye health.
Sunglasses can help your eyes in two important ways. They enhance the normal light-filtering capabilities of your eyes and they protect against the sunâ€™s damaging ultraviolet rays that cause amongst other conditions cataracts and retinal dysfunction. Good sunglasses will reduce glare, filter out 99 to 100 per cent of ultraviolet (UV) rays, provide visual protection, be comfortable and not distort colors.
By now, most people should be aware of the dangers of exposing the skin to too much sunlight, and the majority of us make an effort to wear suncream on sunny days in order to protect our skin from wrinkles, premature ageing and skin cancer.
However, a lot of people forget that the same harmful rays from the sun can also damage our eyes and lead to conditions such as cataracts, macular degeneration and eye strain. This is why wearing sunglasses on sunny days is just as important as wearing sun cream.
Sunglasses protect your eyes from debris. If you engage in outdoor activities, wearing sunglasses can help deflect dirt and other particles from finding their way into your eye.
Sunglasses prevent squinting and watery eyes from the sunâ€™s brightness and glare from interfering with comfortable vision and the ability to see clearly.
When your purchase sunglasses, look for a statement on the amount of UV radiation that is blocked from reaching the eye. The rule of thumb is the less UV rays that get through, the better. Experts recommend that to protect your eyes from harmful rays, sunglasses should block 99 to 100 per cent of both UV-A and UV-B rays. Since as much as 50 per cent of sunlight comes from overhead and gets by many glasses, a brimmed cap or hat should also be worn for maximum protection.
Eyewear that wraps around the face also helps minimize the amount of harmful light entering the eyes. Remember behind a dark lens your eyes open up to try and compensate for the reduced amount of lighting, if your sunglasses are therefore not filtering out the harmful UV rays you will increase your exposure and risk of sunlight related eye problems!
You rely on your eyes to help you maintain your independence. They allow you to continue to do the things you love to do. These very essential organs of your body are also fragile. Prescription sunglasses can help you keep them healthy and your eyesight strong.
