Most people have heard of the advantages
of polarized lenses. but not all are aware of just what they are
and how they work.
A polarized lens acts like a filter or lattice which only
allows the useful light traveling from the object viewed to
reach the eye, while blocking all the glare caused by the
scattered light traveling in many random
directions. Objects then appear sharper. Colors are
more vivid and in true natural proportion due to the removal of
scattered white light.
Regular sunglasses, regardless of the
cost, are only colored plastic or glass and cannot block out
glare. These ordinary sunglasses just reduce the amount of
visible light the eye sees, but the problem of glare still
remains. Polarized sunglass lenses should be of ophthalmic
quality - the same as is expected from lenses used in
prescription eyeglasses.
Polarized lenses are available to fit
the requirements of all those who demand optical quality
sunglasses. They can be purchased as plain lenses (without
prescription) or with your prescription in single vision,
bifocals, progressives or trifocals.
