The dangers of UV rays on your eyes

UV rays (or Ultraviolet Rays) can be very dangerous to your eyes and are divided up into UV-A and UV-B rays. Macular degeneration, growths on the eye, skin cancer of the eyelids, corneal sunburn and cataracts are all potential side effects from the sun’s radioactive rays.

UV-A Rays

UV-A rays account for 95% of the radiation rays reaching the earth’s surface. Although UV-A rays appear to be less intense then UV-B rays they are more predominant. UV-A can damage your central vision such as the macula, this is part of the retina located at the back of the eye.

UV-B Rays

UV-B Rays are more hazardous to your eyes. These rays damage the front part of your eye (the cornea and the lens). The rays intensity can vary throughout the year but are particularly strong during the summer when the sun is higher up in the sky. This can be between 10am-4pm as the sun is above you it has less surface ozone layer to filter out the harmful rays. However if someone is active in areas such as snow or water with high reflecting surfaces, precaution is advised.
