Summer officially starts this Sunday and according to the ophthalmologists, here are five tips for buying a good pair of sunglasses.

Just like sunscreen, a good pair of sunglasses are an essential part of any West Texan's wardrobe. Eye doctors have some helpful hints when fining the right pair for you.

1.  Make sure they have 100% U.V. protection.  U.V. rays are radiation from the sun that can make you develop cataracts and a survey last year found less than half of us check the U.V. sticker on sunglasses before we buy them. Check the tag the next time you buy a cheap pair at your local 7-Eleven store, some of those only block about 40% of U.V. rays.

2.  Big sunglasses are better, because they keep more of the U.V. rays out. Ideally they should be oversized, and wrap around your face.

3.  The color of the lenses doesn't matter, and neither does how dark they are. Lighter lenses can still block all of the U.V. rays.

4.  Polarized lenses reduce glare, not necessarily U.V. exposure; so if you're buying polarized sunglasses, make sure they block 100% of U.V. rays too.

5.  Don't break the bank. You don't have to spend a hundred bucks to protect your eyes.  $10 sunglasses with 100% U.V. protection work just as well.

I hope these tips helped, so go out and enjoy Summer!
