A reflection of good eye health is in the lens

A pair of Ray Ban sunglasses like these can start at $100.

When was the last time you really looked at the protection your sunglasses provide?

Eye specialists say you should make your next purchase not with fashion in mind, but health.

Many sunglasses may come with a sticker label saying they're 100 percent covered when it comes to blocking out those harmful rays, while in fact, it's just a coating on top of the lens that can chip and wear in all types of weather.

"I would call it something that's painted on. It's not even a quality product. You're just getting something that could chip, fade. You're going to go to a pool and the chlorine will eat away at those lenses. Salt water in the ocean can chip away at the lens as well. So, for $10, you're getting what you're getting," Ryan Hulett, with All About Eyes in Quincy said.

Hulett says you want to get a lens that has the protection built in.

People with blue and green eyes are most sensitive to the sun's rays and should wear darker lenses. People with darker eye colors can usually get by with a lighter lens.

"When you come for lenses, it's about your vision and acuity. You definitely want to get something more protective from the sun than just your normal, run of the mill shop at the shopping center for $10 sunglasses. The polarized lenses are going to be better protective of the eye, UVA, UVB protection from the harsh sun rays," Hulett said.

Hulett says a good pair will cost you. Quality sunglasses can run anywhere from $100 to $300.
