What to look for in sunglasses.

Summer is here, and the sun is shining bright.  This is the time of year that sunglasses shift from fashion accessory to a necessity.  But did you know that sunglasses, like sunscreen, have a protective role to play?  By blocking the UV rays that can penetrate the eyes, they can reduce the risk for certain eye diseases, such as cataracts and macular degeneration.  Not all sunglasses are created equal, though.  The best ones will offer protection from all UV’s.  Here, you need to look for UV400, or 100% UVA and 100% UVB on the label.  Tints are a matter of preference, so pick the shade that seems to give you the most relief from the glare.  And if you want more glare reduction, a polarized lens will help to reduce eye fatigue caused by excess light scattering.  The best sunglasses offer full UV protection, with lenses that offer minimum distortion.  These are more expensive, however the reduced eyestrain is worth the investment.  So, summer is here.  Get your shades on!  Your eyes will thank you.
