Choosing Sunglasses That Enhance Your Style And Protect Your
Eyes
Whether you pick them up at a discount retailer or from a
designer boutique, sunglasses are definitely must-have
accessories regardless of the season. However, far from being
just a fashion accessory, sunglasses are multipurpose tools that
can protect your eyes from harmful UV rays and provide a degree
of shade on a sunny day, improving visibility and lessening your
chance of being temporarily blinded by sunlight (particularly
important while driving).
As wonderful as sunglasses are, all sunglasses are not of the
same quality and it is important to take care when shopping for
a pair. The most important consideration when purchasing
sunglasses is to find a pair that provides full protection from
ultra violet (both UVA and UVB) rays, which are generated from
the sun even on cloudy days. While experts disagree about
possible negative effects UVA rays may have on the eye, it is
known that UVB rays can cause a number of eye conditions
including permanent retinal damage, so make sure your sunglasses
are rated for full UV protection.
Sunglasses come in a variety of styles and types. If fashion is
your main consideration, pick a stylish frame and then have
custom lenses with UV protection added to them. If sun
protection is your primary concern, pick up a pair of wraparound
sunglasses that will block light that would normally skip past
the frames of regular sunglasses.
After you've found a style that you like, think about the
lenses. You've probably seen sunglasses with different colored
lenses. While on cheap plastic sunglasses color may be little
more than a fashion choice, with proper lenses, the color can
tell you more about the purpose of the sunglasses. Knowing the
different kinds of lenses will help you make the best decision
when choosing sunglasses.
* Photochromic lenses change color depending on the amount of UV
light to which they are exposed, although for the most part,
they appear darkly shaded when outside, and light or clear when
inside. Photochromic lenses create the illusion of sunglasses
and regular glasses in one package.
* Amber-colored lenses tend to block blue light. There is
discussion about whether blue light is harmful to the eye, but
outdoors lovers agree blue-blocking lenses are super on the ski
slopes or while hunting or fishing.
* Mirror-coated sunglasses limit the light that reaches your
eye, which may make it easier to see in very bright situations.
* Gradient lenses, as the name implies, are those that are
tinted at different opacities from the top down or from the
bottom up. Top-down gradient lenses in sunglasses are great for
driving and viewing the controls clearly.
* Polarized and anti-reflection-coated sunglasses reduce the
amount of reflected light reaching your eyes, which is great in
super-bright situations such as in the snow on a sunny winter
day.
Nearly every style of sunglasses, lenses and frames, can be made
to accommodate special prescriptions so that even those with
poor vision can benefit from wearing sunglasses.
