Even After Summer, We’ve Got to Watch Out for UV Exposure to The Eyes
- Posted on: Sep 30 2019
At the beginning of summer, people tend to have numerous outdoor activities planned. Just a few months ago, we were considering how to make the most of the warmth that had finally arrived. One of the tips we often hear for a safe and healthy summer is to protect the skin from the strong UV rays of the sun. Additionally, many people are now aware that they need to wear sunglasses to prevent UV damage in and around the eyes. With summer coming to an all-too-soon end, this is a tip we don’t want to forget anytime soon. We’ve still got some time before the weather may keep us indoors more often, so eye protection remains an important matter.
What Are UV Rays, Anyway?
Sunlight contains three types of UV rays, also known as UV radiation. There is Ultraviolet light A, B, and C (UVA, UVB, and UVC). The most dangerous of them all is UVC. However, most of these rays currently get absorbed by the natural ozone layer before they reach earth (which means only astronauts need to worry about them!). UVA and UVB rays both pass through the ozone layer, and both can damage the cornea layer at the front of the eyes. UVA rays, though weaker, pass even farther through the eye and hold the potential to damage the retina at the back of the eye.
Ocular Effects of UV Exposure
When we spend time outdoors without proper sunglasses, we may experience several uncomfortable symptoms and even an increased risk of eye disease later in life. Soon after sun exposure, symptoms such as tearing, light sensitivity, blurred vision, and redness can occur. This can even happen in the winter as light reflects intensely off the snow. Repeated exposure to sunlight without the use of sunglasses increases the risk of cataracts and macular degeneration, two potentially serious conditions that threaten sight.
We may not need to wear wide-brimmed hats during the Fall and Winter months, but we do still need to wear sunglasses to prevent unnecessary damage to the eyes.
