What about infrared rays?
While the red portion of the light spectrum is visible,
infrared is just beyond red and invisible to the
human eye. Some experts
believe that in certain conditions infrared light can be harmful to your
eyes.
While others claim that infrared
is not a threat to your vision. You
decide.
Which color lens should I select?
There is a wide array of colors to choose from in selecting
a pair of sunglasses. While there may be
some advantages and disadvantages, it still remains a personal choice. For
example, shooters and
skiers prefer yellow tinted lenses to increase the
contrast in low light conditions and provide crisp
vision. While others opt for gray or brown as these
lens give the least amount of distortion to the
field of view. In the end, some
colors are just a fashion statement. When your eyes require a
correction to help you see better, you should consider
prescription sunglasses.
Should I consider impact-resistant lenses?
By Federal regulation, all sunglasses must be manufactured
in a way that makes the lens resistant
to impact to some degree. If you are an athlete, the best protection for
your eyes today are
polycarbonate lenses specially designed for their impact
resistance.
My sunglass lenses are dark. Should I still be concerned
about UV rays?
The answer is yes. The dark lenses may diminish the amount
of light reaching your eyes but the lens
darkness in itself does not protect
against UV intrusion. For maximum
protection always get
sunglasses that block 100% of the UV rays.
Are expensive sunglasses better quality?
The cost of a good pair of sunglasses is not always the best
indicator of quality. While expensive
sunglasses are usually of high quality, lesser
cost models can also be more than adequate if the
glasses have all the right
characteristics that we have previously discussed.
Do my children need sunglasses?
Children are typically outdoors more often then their adult
counterparts. Due to the exposure and
their general sensitivity, children can be more at risk that adults for
potential damage to their eyes.
So the
answer is yes. To ensure a lifetime of undamaged vision children should wear
protection for
their eyes when out of doors.
What choices do I have if I wear prescription glasses?
Both prescription sunglasses or photochromic lenses would be
your best options. Other choices
include clip-ons or magnetic attachments that
fit directly onto your regular eyeglasses.
I'm an athlete. Should I consider sunglasses for playing sports?
Most definitely, yes. Sports eyewear can serve two
purposes. First, they are usually
constructed
to be stronger and more shatter resistant than other frames and
lenses. And secondly, all the
benefits
of sunglasses are available in sportswear models. So not only are they safer
but they can
help the athlete perform better whether on the links, on the
baseball diamond or skiing down the mountainside.
