|Although there is plenty of advice available
on what style sunglasses looks best on what
shaped face, whatís the latest fashion, and
what is the best buy, sunglasses today are
more than a fashion statement: they are an
important way to protect your eyes from sun
damage. Whether you get your sunglasses at
the corner store or special order them, here

- Lens should block both UVA and UVB radiation
to protect eyes from cataracts and eye diseases.
- The color of tinted lens should match the
type of activity you are doing

activities, especially in snow or water.
- rose provides good depth perception and contrast
in low-light conditions for
cloudy weather and against
- Lens made from polycarbonate are durable
and lightweight but tend to break and scratch
more easily. Glass is durable but is heavier
and might be uncomfortable to wear. Acrylic

- Polarized lens block the reflected light
from snow, water and highways and are good
for skiing, water sports, mountaineering

One last note, sunglasses are not just for
adults. Special glasses are made for children
and babies (the frames are soft and bendable)
because itís never too early to start protecting
