Choosing Sunglasses
Make sure the lenses are dark enough to keep your
eyes comfortable, but not so dark that they reduce
your vision. If you spend a lot of time outdoors in
intense glare from sunlight bouncing off snow or water,
you should wear sunglasses that block blue light.
Medium to dark lenses with a grey, or a slightly brown
or green tint, will filter out most blue light.
Most sunglasses have plastic lenses. These lenses
are tougher than glass and less likely to shatter.
If you buy plastic lenses, look for a pair with a
scratch-resistant coating. Check the lenses for distortion
by putting the sunglasses on and looking at a rectangular
pattern, such as floor tiles. If the lines stay straight
when you move your head up and down, and side-to-side,
then the amount of distortion is acceptable.
Sunglasses are made with different kinds
of lenses to meet different needs:
-
Regular lenses reduce the brightness
of everything evenly.
-
Polarizing lenses are designed
to cut glare due to reflection. This means they
are good for driving and outdoor activities in the
snow or on water.
-
Photo chromic lenses change
with the intensity of UV light by turning darker
when outdoors and lighter when indoors. If you wear
these for driving, choose sunglasses that are fairly
dark.
-
"Flash" or mirror lenses
reflect all or part of the light instead of absorbing
it. They offer no performance advantage as they
scratch easily. You should choose a pair with a
scratch-resistant coating.
