DEAR DOCTOR K: During my last eye exam, my eye doctor advised me to buy a pair of "high quality" sunglasses. But she didn't tell me what she meant by high quality. Can you help?
DEAR READER: When you buy sunglasses, it's natural to look for a style that looks good on you and is comfortable. But don't fail to consider the most important detail: the amount of harmful ultraviolet (UV) radiation the lenses screen out. Without proper UV protection, sunglasses can work against you by enabling you to see comfortably in light that is harming your eyes.
