UV-A
and UV-B cause cataracts and damage the sensitive
retina, sometimes impairing vision to the
point of blindness.
Zurich Sunglasses Block 100% of UV-A and UV-B .
Ordinary sunglasses actually worsen UV-A damage - a real concern,
because sunlight now has more UV-A than ever before, particularly
in high-altitude ski areas.
UV-A and UV-B are the culprits
"The increasing amount of UV-A sunlight is one more chapter
in the ongoing tale of environmental destruction. Perhaps you've
already read about the problem.
Ozone Damage Harms Eyes It’s happening in the upper atmosphere, where a layer of
ozone (O³) gas filters out practically all UV radiation from
the sun and protects our eyes or at least used to. In recent years
chloroflourocarbons in aerosols and refrigerants have depleted the
ozone layer letting much more harmful UV-A radiation through to
the earth’s surface. Because of the danger, aerosol chloroflourocarbons
are now banned in the United States and controlled by a recent international
treaty, but great harm has already been done. We’re now beginning
to see the health results.
The Environmental Protection Agency predicts 600,000 additional
cases of sight-threatening cataracts due to the “ozone factor”.
That’s a frightening statistic.
What’s even more frightening is that some sunglasses actually
increase the damage sunlight does. The pupil dilates behind a dark
lens, so more UV-A light enters the eye.
That’s why if you spend time in the sun you need real protection
against increasing UV-A radiation in sunlight.
