Do I need to purchase sunglasses with UV protection after my LASIK procedure and why is that important?
Protecting your eyes is from too much sun exposure and harmful UV rays is just as important as protecting your skin with sunscreen in the warm weather months. Tinted, polarized lenses that have UV protection are imperative for protecting your eyes against harmful UV rays.
The accumulative effects of UV rays over time can compromise your eye health.This article by the American Optometric association explains why protecting your eye from sun exposure is important for your eye health:
“Most are aware of the harm UV radiation can do to the skin, but many may not realize that exposure to UV radiation can harm the eyes or that other components of solar radiation can also affect vision.
There are three types of UV radiation: UV-C is absorbed by the ozone layer and does not present any threat; UV-A and UV-B radiation can have adverse long- and short-term effects on the eyes and vision.
If your eyes are exposed to excessive amounts of UV radiation over a short period of time, you are likely to experience an effect called photokeratitis.
