Many of you are buying suntan lotion and other accessories to protect you from the sun this season. Wearing the wrong kind of sunglasses can be a real eyesore in the long run. Texas Tech Medical Center's Dr. David Smith explains why owning the right kind of shades is key to protecting your sight. From the inexpensive to the most expensive to the colorful and polarized, sunglasses for the most part are safe. Sunglasses have ultraviolet blockers to protect you from diseases like macular degeneration, cataract and tumors in your eyes. But, Texas Tech says there are the exceptions. "Smaller sunglasses are not as good because they don't protect the eyelids from the ultraviolet exposure which can lead to eyelid cancer," said Dr. Smith. To prevent that from happening, look for a pair of sunglasses with 100 percent UV protection. But, if you decide not to wear sunglasses, you could damage your eyes permanently. "The three things that were trying to prevent here, the cataract, macular degeneration and the tumors, take a long time to develop and they really don't give signs along the way," said opthamologist Dr. David McCartney. "They're pretty silent. So its something you have to pay attention to, be knowledgeable about and take self protection," said McCartney. Smith says your best bet is to buy sunglasses, that have a larger lens and a wide frame that provides all around protection.
