Protecting Yourself from UV Rays

It's a fact that basically everybody is exposed to UV rays. However, the potential risks of many years of exposure to these harsh rays aren't really considered, to a point where most people take little action to shield their eyes, even if they're expecting on being exposed to the sun for an extended period of time. Being exposed to too much UV is unsafe and cannot be reversed, and may also lead to several serious, vision-stealing conditions down the road. This means that ongoing protection from these rays is extremely important.

UV radiation, which originates mostly from the sun, consists of 2 sorts of damaging rays: UV-A and UV-B. Even though only small measures of UVA and UVB light hit the inner eye, the ocular tissue is extremely receptive to the harmful effects of their rays. Even in the short term, small amounts of exposure can lead to sunburn of the eye, often referred to as photokeratitis. When UVB rays are absorbed by the cornea, the cells that make up its exterior are significantly damaged, which can lead to blurred vision, pain or even temporary blindness. UVA rays actually penetrate much deeper into the eye, which harms to the retina. Over a number of years, being exposed to UV rays can cause substantial damage to the eyes and vision. Out of the 20 million people who suffer from cataracts, an estimated 20 percent are caused by long-term UV exposure.

A really great way to guard your eyes from UV rays is through the use of high quality eyewear. Check that your sunglasses or prescription eyewear block 100% of both UVA and UVB rays. An insufficient pair of sunglasses can actually be worse than using no sunglasses at all. Think about it this way: when your sunglasses don't give you any UV protection, you are actually getting more UV rays. Such sunglasses will block some of the light, causing your iris to open and allow more light in. And this means that more UV will reach the retina. Always check to make sure your sunglasses give effective UV protection.
