Remember Your Sunglasses This Summer

Most of us know how important it is to use sunscreen to protect our skin from harmful UV rays. However, many people don't know that the surface tissues of their eyes are just as much at risk from sun burn as their skin. Read on to find out why you should be sure to pick up a pair of sunglasses this summer.

Short-Term Effects of UV Radiation
Even a single day playing in the sun at the beach can cause adverse effects to your eyes. Photokeratitis is one of the dangers of short term sun exposure. Something like a sunburn on your eye, photokeratitis can be painful, and causes symptoms such a gritty feeling in the eye, extreme sensitivity to light, excessive tearing and red eyes. But, fortunately the effects are usually temporary and a gentle reminder from your eyes that you need sunglasses.

Long-Term Effects of UV Radiation
Although the symptoms of Photokeratitis are mild, repeated cases can seriously damage your eyes. Sun bathers who leave their sunglasses at home are not only damaging their retina, the part of the eye that controls sight, but they also significantly increase their chances of developing cataracts and other growths on the surface of the eye. And unlike photokeratitis, this damage is irreversible.

Sunglasses Matter
Sunglasses are just as important as sunscreen and should be worn every time you intend to spend a while in the sun. However, not just any drug store pair of sunglasses will do. Especially if you spend extended periods of time outside in the sun. Look for sunglasses that block out 99-100% of UV A and B radiation and screen out 75 to 90% of visible light. Furthermore, for those that work outside, wraparound lenses are a good idea for those who work or spend more than four hours a day outside.

Especially for Children
Getting small children to wear sunglasses can be a cinch or a pill, depending on the kid. To encourage your child to wear sunglasses and start a lifelong habit of proper eyecare, be sure to involve them in the process. Take your child with you and let them pick out their own glasses. They will be much more fond of a pair tht they picked out themselves. And wearing your glasses religiously will make your little one want to copy you. But if it becomes clear that your child just will not wear sunglasses, try wide-brimmed hats that will provide protection and teach them not to look directly into the sun.

Even For Those Who Wear Glasses
For those who don't want to let go of their glasses, there are several options to block out harmful UV rays. Consider buying tinted lenses that block a significant amount of UV rays. Or opt for photocromatic lenses that darken in the sun and lighten indoors (however, they don't always darken inside of cars). But, perhaps the least expensive option for those who don't want to invest in a perscription pair of sunglasses is a pair of clip on sunglass lenses available at every eyestore.
