Sunglasses 101
Here you can learn which types of lenses would better suit you and help optimize your lifestyle any time you are outdoors. This is the time of year most of us start thinking about sunglasses, but we should wear them all year round! Some things to keep in mind:


  • Long-term exposure to UV radiation can not only damage the outside of the eye but also internal structures can be greatly harmed. Therefore, protecting our eyes while in sunlight is very important.

  • Exposure to UV rays, according to the Glaucoma Research Foundation, can contribute to cataracts as well as macular degeneration. These are two very serious conditions that can not only lead to blindness but also affect our overall eye health.

  • It is highly recommended to wear sunglasses anytime we are in the sun long enough to get a sunburn or sun tan.

That being said, finding a lens that will help us comfortably see while outdoors and also protecting us from harmful UV rays is what we should look for.




  • As the Glaucoma Research Foundation mentions, always choose sunglasses that are labeled as blocking 99-100% of UV rays. Some manufacturers’ labels say "UV absorption up to 400nm." This is the same thing as 100% UV absorption.

  • Be sure there is minimal room around the eye for rays to sneak in from the sides, above and under the lenses.

  • One last thing to check for proper protection from the sun and UV rays would be the darkness of the lens – if you can see your eyes through the lens, you should try to go a little darker.


Protecting our eyes from harmful substances and sunlight is the key to maintaining eye health, in addition to annual exams. Sunglasses are important any time the sun is shining. Summer time of course, but the rest of the year is just as crucial.
