Here’s What Happens When You Don’t Wear Sunglasses


Sunglasses can make you look cool. They also keep you from squinting into the sun. But they can do much more. At Clarity Vision Care, we want to help you to protect your vision. Here’s why we believe sunglasses can do just that.

The right sunglasses can help preserve your vision and reduce your risk for certain eye diseases. Bonus benefit: The right pair of sunglasses can also reduce fine lines and wrinkles in the delicate area around your eyes.

What does the “right pair” of sunglasses mean? It means that your sunglasses don’t just look good on you. They need to come with both UVA and UVB protection. UVA and UVB are the primary ultraviolet rays that emanate from the sun.

Why you need good sunglasses

Too much exposure to UVA and UVB rays is not good for you in many ways. Prolonged UV exposure can affect your skin, leading to sunburn and skin cancer, as well as problems with your eyes. Sunglasses block these rays from harming your eyes in the same way that sunscreen prevents these rays from damaging your skin.

They don’t have to be expensive to be good sunglasses, but often the cheaper kind you buy in a drugstore or on the street don’t have this type of protection. Here’s what to look for when you buy your next pair of sunglasses:

  • 100% UV protection, which protects your eyes against both UVA and UVB rays
  • Polarized lenses, which protect against sun glare
  • Wraparound frames, which prevent the sun from sneaking in on the sides

What happens to your eyes without sunglasses?

Just like it’s been drilled into your head that you need sunscreen every time you go out into the sun, wearing sunglasses is equally important to protect your eyes from the sun’s harmful rays. Plus, it’s more comfortable for your eyes to face the sun with a good pair of shades. Here’s what could happen to your eyes if you don't wear sunglasses:


Cataracts are a clouding of the lenses that gets progressively worse over time. Eventually, the clouding impacts your vision. About 20% of cataracts are the result of UV exposure.

Macular degeneration

Prolonged UV exposure can increase your risk for macular degeneration, which is caused by damage to the retina. Macular degeneration is the leading cause of blindness in the United States.


Pterygium, also called surfer’s eye, is a membrane growth that covers the white part of your eye. It’s the result of UV exposure as well as exposure to other elements such as wind and sand. Sunglasses can protect your eyes against all elements.
