Polarized Sunglasses

Polarized lenses have surpassed polycarbonate lenses as
the fastest-growing category in lens sales. Today's polarized
lenses come in a spectrum of possibilities. Not only are
polarized lenses available in many styles from single vision
to progressives, they now come in many different lens materials
and colors, too. Even photochromics are now available in
a polarized version.
How They Work
Polarized lenses contain special horizontal polarizers
or filters that help reduce glare off water and things such
as paved roads. They also help enhance colors and vision
in some high-glare situations. The lenses are invaluable
in high-glare situations, such as driving, boating, golfing,
surfing, and fishing. Polarized lenses also help reduce
glare, which can be a real problem in water sports and many
other outdoor activities.
Which Color Lens is Best?
 |
Some lens colors perform better than others,
depending on lighting conditions and environment. For
example, a dark gray tint works best for intense glare
and bright sunlight encountered when driving, boating
or deep-water fishing. Melanin and Brown C tints improve
contrast and work well in bright conditions for golf,
snowmobiling, and shallow water fishing. Green works
well on bright days for tennis and baseball. Orange
and yellow tints block blue light, and perform best
under low-light or overcast conditions. These may be
used for shooting, biking, and skiing. Red works well
for low-light fishing, skiing, while violet or purple
can be used for golf on overcast days. |
Patients with macular degeneration (or at risk for it),
should consider a Melanin tint. Melanin is a golden brown
color that provides the most UV protection while maintaining
true color balance.
Some polarized lenses can block the reflected light of
LCDs, too. These are the lights in many dashboards, bank
automated tellers, and other electronic devices. So, if
you use a PDA, laptop, or have an electronic dashboard,
you may want to check and make sure that the polarizing
lenses you choose will not block out LCD light, too.
