Sunglasses
Although there is plenty of advice available
on what style sunglasses looks best on what
shaped face, what’s 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
are some features you should look:
- 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
- gray, brown and green don’t distort color
and are good for medium to bright conditions
and everyday activities.
- yellow and amber gives good contrast and
good depth perception; good for sports and
activities, especially in snow or water.
- rose provides good depth perception and contrast
in low-light conditions for
activities in
cloudy weather and against
blue/green backgrounds
like boating.
- 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
is inexpensive but may provide some distortion
and be less durable.
- Polarized lens block the reflected light
from snow, water and highways and are good
for skiing, water sports, mountaineering
and driving.
- Frames are made from a variety of materials.
Metal ones can be more easily adjusted to
fit your face. Nylon frames usually aren’t
adjustable but are more durable and less
expensive. Frames with special springs that
let the frame bend/flex provide protection
against breakage.
- Glasses with side shields, wide earpieces
or that wrap around the face help stop light
from entering from the sides of the glasses.
Besides offering protection from light, they
also protect against rain, wind, and bugs
-- all of which make them good for cycling.
One last note, sunglasses are not just for
adults. Special glasses are made for children
and babies (the frames are soft and bendable)
because it’s never too early to start protecting
your eyes. |
