When you go outdoors for any activity, glare can be a
serious problem. It is not only bothersome
and annoying, but it can be down
right dangerous. For automobile drivers, vision impairment can
result in accidents as the sun’s rays scatter off
of the road or even the surface of the car itself.
The latest in eyewear technology can help avoid these catastrophes.
However, the simple
use of polarized sunglasses can help reduce or even eliminate the glare
reflected from flat surfaces. Sports enthusiasts such as fishermen, golfers and
skiers have
known the benefits of polarized optics for many years. Now more and
more people are learning
what polarized shades can do not only as fashionable
eyewear but as sensible eye protection.
Light from the sun is constantly reflected from flat
surfaces. This causes glare which is
generally
horizontally polarized. Due to the physics of light waves, this
horizontally polarized light can be
blocked by vertically polarized lenses. Thus
you can virtually eliminate glare with a pair of polarized
sun glasses.
While polarized optics are very successful in reducing
glare, they have their limitations. Using
polarized sunglasses makes it nearly
impossible to read displays from a liquid crystal display (LCD).
LCD screens
are found in many places such as ATMs and car dashboard dials. Again due to the
light wave mechanics, if you are at the exact angle of extinction, LCD monitors
can appear invisible
when wearing polarized lenses.
But for the majority of people the benefits of using
polarized sunglasses clearly outweigh the negative
aspects. The eye protection
and safety advantages of polarized sunglasses are ideal for anyone who
goes outdoors;
hikers, sportsmen, golfers, skiers, gardeners, drivers and more. Even fishermen
can
use polarized sunglasses to eliminate the glare of the sun off of the water
surface. This makes the
water look as if it is transparent making it easier to
see logs and other habit in the water or even the
fish.
Whether you use them for recreation, avocation or vocation,
polarized sunglasses provide
incomparable protection for your eyes from the glare
and harmful effects of the sun. |
