Polarized Sunglasses
Probably our most important sense is vision
and it is this ability that has the greatest
chance of being damaged. Dust, debris,
flying insects and chemicals are all
dangers, but sunlight can pose the greatest
risk of all to our vision. The sensitive
mechanisms in our eyes can be burnt out by
excessive ultraviolet light radiation. The
best way to protect the priceless gift of
vision is with a quality pair of polarized
sunglasses for use outdoors.
Edwin Land developed the polarization
process in 1936 while experimenting with
camera lenses for his patented "Polaroid"
film. The way polarized sunglasses work is
that most reflected light off water, snow or
flat surfaces is directed in a horizontal
direction. There are special built in
vertical polarizing lines within the
sunglasses lens that cancel these horizontal
rays out thus reduce the amount of glare
that passes through. This is the basis of
sunglass "science".
Fishermen enjoy some of the best advantages
for polarized sunglasses as it cuts glare
off the surface of the water thus making it
easier to see your line and the fish upon
it. Water-skiers and boaters also enjoy this
benefit from polarized sunglasses that cuts
the glare out of their eyes. Drivers and
pilots also can benefit well from the
reduced glare you get with polarized
sunglasses. There is some debate as to
whether this polarized sunglasses effect is
useful in snow conditions.
The polarization process can be applied to
prescription sunglasses as easily as to
cheap polarized sunglasses. Because
polarized sunglass lenses are the most
common forms of lenses they can be easily
personalized. In fact it is through a
polarizing method that sunglasses can have
designs painted on the lenses and yet you
cannot see the design from behind them. It
has been polarized out of your view.
Adding a quicksilver coating to polarized
sunglasses will produce a mirror effect. You
can purchase polarized photochrome lens
sunglasses. These photochromatic sunglass
lenses are the ones that have a molecularly
built in system that darkens when light
intensity increases and will fade all the
way back to clear in a low light
environment.
Almost all sunglasses designers make
polarized lens sunglasses but some of the
best come from Costa Del mar, Ray-Ban and
Nikon. DSM also rated with the best for
polarized sunglasses and because of the
combination of high quality frame materials,
exacting construction and carefully crafted
lenses, the number one choice of polarized
sunglasses is Oakley Optics.
