The Impacts of UV Exposure on Eyes

The sun releases energy or radiation in different forms. One form we see in our naked eyes is the sunlight. Another form we feel is the heat. UV or ultraviolet rays is the third type and is invisible to the eyes. They can cause sunburn and damage your eyes during an impact on vision.

There are two different types of UV rays, like UV-A and UV-B. Over time, the effects of UV rays can result in a great number of eye problems. 

UV-A

This ray can affect your central vision and damage macula, an important part of the retina at the back of your eye. 

UV-B 

The front part of your eye, usually the lens and the cornea, absorbs most of the UV-B rays; but they may damage your eyes even more than the UV-A rays. 

The Eye Problems UV Rays can Cause –

Cataract –

UV rays, generally UV-B rays may cause some types of cataracts. A cataract is nothing but the clouding of the eye’s natural lens – the part of the eye focuses on the light we see. 

Skin Cancer –

The prolonged UV exposure can lead to skin cancer around the eyelids. 

Macular Degeneration –

UV rays may cause macular degeneration – the main reason behind the vision loss for older Americans. 

Corneal Sunburn –

Corneal sunburn is also known as photokeratitis, which is caused due to the high short term exposure to UV-B rays. When you spend long hours at the beach or go skiing without proper eye protection, you can be the candidate for this eye problem. It can be quite painful and can cause vision loss temporarily.

Pterygium –

Another eye problem is known as pterygium. It starts on the white part of the eye and may involve corners. This problem may eventually block vision. It’s quite common in people who work outside in the sun and wind. 

Protection against UV Ray Exposure –

UV rays can come from different directions. They radiate directly from the sun and reflections from the ground, water, snow, and other bright surfaces. If you want to protect your eyes from maximum exposure of harmful UV rays, you should use eyewear that absorbs UV rays. 

Moreover, the eyewear that absorbs UV rays can provide an enormous level of protection to eyes. All types of eyewear, like contact lenses, lens implants, prescription glasses, etc. can absorb UV-A and UV-B rays. 

If you need UV protection in daily eyewear, there are different options available like UV-blocking lens materials, coatings, and photochromic lenses. However, UV protection glass doesn’t cost you more and get in the way of seeing everything.

 

Bottom Line –

For prevention, you can wear UV-blocking sunglasses and round hats while enjoying outdoors, even on cloudy days. Teach your kids not to look directly at the sun. Wear goggles for the protection of eyes from the consistent exposure to dust.
