That cooler weather has arrived (I think)!  Many of us are trading our hot weather walking gear for cold weather gear.  However, one item that is essential for all seasons that that should not be packed away are sunglasses.

A good pair of sunglasses can protect your eyes from harmful ultraviolet radiation found in sunlight.  The harm ultraviolet radiation causes does not happen overnight.  But years of exposure beginning in childhood, to the sun's UV-A and UV-B radiation may result in eye health problems, such as cataracts and macular degeneration when you get older.

Overexposure to UV radiation can cause benign (non-cancerous) growths on the eye's surface; cancer of the eyelids and skin around the eyes; and temporary but painful sunburn of the eye's surface (photokeratites).  Wide-brimmed hats can block up to 50% of UV radiation, but to get maximum protection you need to wear sunglasses that block 99 to 100% of both UV-A and UV-B.

To help you find sunglasses (nonprescription) that provide good sun protection follow these tips:

     1.     Don't be misled by labels.  Look for the American Optometric Association's seal of acceptance or buy sunglasses where equipment is available to check UV protection capabilities.

     2.     Chose a gray, green, or brown lens tint (it won't hurt if they look awesome).

     3.     Hold the glasses at arm's length.  Look through them at a straight line in the distance, such as the edge of a good.  Slowly move the lens across the line.  If the straight line distorts, sways, curves, or moves, the lens has imperfections.

     4.     Try the classes on in front of a mirror.  If you can see your eyes easily through the lenses, they probably aren't dark enough.

     5.     Check lenses to be sure the tint is uniform, not darker in one area than another.  With gradient lenses, be sure the tint lightens gradually from the top to bottom.

For maximum protection of your eyes don't forget to wear those sunglasses not just on sunny days but even on those bright, cloudy days.  See you on the trails.
