The summer
sun's harmful ultraviolet (UV) rays can cause extensive eye
damage, including cataracts, macular degeneration, corneal
burns, and eye cancer, according to experts at the New York
Eye and Ear Infirmary.
"The
best way to prevent these problems is to wear sunglasses with
100 percent UV protection," said Dr. Paul T. Finger,
director of Ocular Tumor Services. "Think of sunglasses
as sun block for your eyes."
People
who work outdoors, have blue eyes or take certain medications
are especially at risk to eye damage from the sun's UV rays.
People taking vacations are also at risk as the reflective
glare of sand, water or snow magnifies sun exposure, according
to Finger.
Care in
choosing the right pair of sunglasses is critical for proper
protection from UV rays.
"Most
brands of sunglasses sold in the United States today have
100 percent UV protection, but some knock-off brands may not,"
advised Finger. "Most all cataract implants, called IOL's,
contain UV blocking agents and can block UV light." Polarizers
and antireflective coatings can be added to any pair of sunglasses
to decrease glare.
