There are three types of rays that the sun emits: visible,
infrared and ultraviolet (UV). Generally,
without added technology, our eyes
can see only portions of visible light. But the most dangerous
of these rays,
that can cause eye damage, are the UV rays. Continuous over-exposure to bright
sunlight can damage the eye including the cornea, lens and retina. If the
damage to the eye is excessive
it can lead to cataracts, or clouding of the
lens, or macular degeneration, a breakdown of the macula. By becoming more educated about the harmful effects of UV
rays on the eyes, you will be better
able to choose quality sunglasses that are
capable of providing lasting protection to you from the
irreversible damage to
your vision that can result from prolonged exposure to the sun. There are
countless sunglass features to choose from that will make your outdoor experience more enjoyable.
Prescription sunglasses are specially designed for people
who need vision correction to see clearly
while also providing protection from
the sun’s rays. Many sunglass companies now make stylist, fashion-conscious
sunglasses that also require a prescription.
Prescription sunglasses are designed to protect the user
from the harmful ultraviolet rays of the sun.
However, polarized lens can provide
added protection for the eyes from glare that occurs when light
is reflected
off flat surfaces such as water or snow. Another great choice is photo-chromatic
sunglasses because they have the ability to darken in the sun yet lighten
automatically when you go
indoors.
Until recently prescription sunglasses were not available in
a wrap-around style. The curvature of
the
lens would cause vision distortion. Now with new technology, prescription
sunglasses are available
with wrap-around making them very fashionably.
If you require custom-made prescription sunglasses, be aware
that they will cost you more and
usually no refund is available from the
manufacturer. Make sure you work with a reputable company
that offers quality
prescription sunglasses and first class service.
