NEW YORK, May 12, 2009 (UPI via COMTEX) -- Two U.S. ophthalmologists say
wearing protective sunglasses helps preserve eye health.
Dr. Donald J. D'Amico and Dr. Stephen Trokel, both of the NewYork-Presbyterian
Hospital/Weill Cornell Medical Center, warn overexposure to the sun can not only
cause skin cancer of the eyelids, but cornea sunburn and vision-blocking tissue
growth. It has also been implicated in the development of cataracts and,
possibly, macular degeneration.
"There are strong indications that chronic exposure to the components of
sunlight may accelerate aging of ocular tissues," Trokel says in a statement.
"Any protective eyewear should have side shield protection or wrap around the
eye so light cannot enter the eye from side reflections."
The doctors advise to get sunglasses:
-- That are labeled "over 95 percent UV protection."
-- That have a lens tint -- such as neutral gray, amber, brown or green -- that
blocks 80 percent of transmissible light, but no more than 90 percent to 92
percent of light.
-- That can be worn over contact lenses because sunglasses help prevent the
drying effects of warm wind.
-- For infants because eyes should always be shaded from direct exposure to the
sun.
