How to protect your eyes from UVA and UVB?

Like sunscreen, sunglasses should be worn all the time outdoor, all year round. UV protection is necessary on cloudy days too. Here are five tips on how to pick out the right pair:

1. Choose the ones that have 99% to 100% UVA and UVB protection.

2. Choose the lenses that has a minimal thickness for sports purposes to protect from injuries.

3. Choose the right hue, brown lenses are great for contrast, improving your sports vision in golfing, volleyball and tennis skills; grey ones are better for water sports, reducing the glare.
 
4. Polarized lenses reduce glare by filtering out the reflected sunlight that
bounces off surfaces like water or pavement. They’re better options for fishing and water sports. It may be harder to read off crystal liquid displays though. Keep in mind that polarization is independent of UV protection, it’s important to check for labels for both.

5. Consider the cost of the lenses, consistency is a concern with lower-priced glasses. You don’t have to buy the sunglasses for the brand, but go for the consistent quality that is known for that brand. To test optical quality, the FDA suggests focusing on a vertical edge or line.
Move your head back and forth, allowing your eyes to sweep across the lens. “If
there is any wiggle in the line,” the FDA guidelines say, “then the lenses may
have an optical defect and you should choose another pair.”

If in doubt, ask your Optometrist or eyecare professional.
