SUNGLASSES
Are
your sunglasses’ lenses
tinted brown, yellow, purple
or blue? What technology
does it use? Is it tinted
or reflective? Or does it
have photochromic or polarizing
qualities in the lenses?
Does it filter out harmful
OVA and UVB rays?
Do
you know how to pick the
right pair of sunglasses
for your needs from the
gazillion pairs you see
arrayed inside counters?
Although sunglasses are
advertised and sold like
fashion accessories, they
are primarily medical devices.
In fact, sunglasses were
created to protect your
eyes from damage and the
deterioration that happens
if they are exposed to harmful
sun rays and other sources
of intense light.
How
can you pick a pair of sunglasses
to suit your needs? Specifically,
here are four ways sunglasses
work to protect your eyesight.
Keep these in mind when
choosing your sunglasses
and you’ll have healthy
corneas and retinas no matter
your age.
There
are four ways sunglasses
protect your peepers. These
are the following:
The
right pair of sunglasses
will give your corneas protection
from the sun’s ultraviolet
rays. Scientific research
has clearly linked the following
diseases such as cataracts,
macular degeneration, snow-blindness,
pterygium and skin cancer,
to the corneas and retinas
over exposure to Ultraviolet
rays. Hence, when you see
stickers on sunglasses that
say UV protection, it means
your sunglasses filter out
UV rays.
An
effective pair of sunglasses
will protect your retinas
from intense light. You
see, your irises shut down
in self protection when
it is hit by intense sources
of light. Your eyes will
then squint if the light
is even more intense. The
longer your eyes are exposed
to this intense and penetrating
light, the harder it is
on your retinas, and when
the damage is done, it can
be permanent.
An
effective pair of Polaroid
sunglasses provides protection
from glare. Many sports
enthusiasts especially those
who go boating, use Polaroid
sunglasses because they
know water reflects back
a great deal of sun. The
glare this generates is
dangerous, for this is often
uncomfortable as to be distracting.
Glare also hides objects
that are in your way.
Depending
on the specific need you
have, your sunglasses will
filter out specific frequencies
of light. There are frequencies
of light so high as to blur
your vision and others will
enhance the contrast between
the lights.
Sunglasses
have evolved into becoming
fashion statements, but
they are first and foremost
medical devices for protecing
your most precious eyes.
So choose wisely. It is
advisable to go naked rather
than wear a cheap pair of
sunglasses at the flea market,
which will do more damage.
