Beyond the lens itself, there are various optional coatings and
treatments which can help improve the performance of the lenses in one's
prescription. Various tints and colors can be applied to lenses to
improve clarity of vision under certain light conditions or enhance the
cosmetic appearance. In addition, there are other coatings and lens
treatments available to help improve the clarity of vision .
Colors, Mirrors, and
Lenses can be dyed to almost any
conceivable color or tint-- brown, grey, blue, green, pink and
more. These tints can be of one uniform shade (solid tint) or in
gradients from the top of the lens as a dark color smoothly transiting
into clear or another color at the bottom. Colored metallic mirrors can
also be put in to reduce glare and ultraviolet and achieve a sporty
appearance. Polarized coatings reduce glare from bright surfaces
such as snow, water, and sand by redirecting the light.
Anti-Reflective coatings or AR
coatings for short are extremely popular in Europe and Asia. AR
coatings are designed to reduce the reflection that shines from the
front and back surfaces of lenses. The result is improved vision
performance and better cosmetic appeal.
AR coats will reduce the amount of glare
caused by the sun reflecting off objects or headlights of vehicles
at night. In addition, the annoying ghost images from the back
side of the lenses are dramatically reduced. The reduction of
glare and ghost images can provide sharper and clearer vision.
Without an AR coat, one's eyes can be
hidden or blurred by the reflection on the front surface of the
lenses. AR coats can make one's eyes more apparent during
important moments of eye contact such as talking to people, being in
pictures or on camera.
Early AR coats tend to scratch and smudge
more easily. However AR technology today has made these coats more
durable and easier to care for. Certain high quality AR coats are
now almost as scratch resistant as glass and all AR coats that we use
come with warranties against scratching, so you can rest assured that
your AR coat will perform as promised.
Photochromatic lenses have a
special invisible layer so that when they are exposed to ultraviolet
light, they will darken to gray or brown. These lenses are
convenient for those who would like a pair of sunglasses, but do not
want to hassle with a separate sunglass pair or clip on sunglasses for
their clear pair of eyeglasses. One drawback to these lenses is that
ultraviolet rays are mostly filtered by the car's windshield, so these
photochromatic lenses tend not to be dark inside a car.
