AR
was first invented in 1935, and its military use was soon
recognized by the Germans, who kept it secret till the
early stages of World War II. By reducing reflections,
AR coatings could increase the amount of light that
reached the eye and improve the contrast of the image
by eliminating stray light. The result was a significant
improvement in the optical performance of a lens.
AR Coatings
Have Become the Option of Choice for Improved Appearance
and Better Vision
While AR coatings were a big boon
to eyeglass lens wearers, early coatings had a tendency
to crack and peel. The coatings were also difficult
to keep clean as they attracted dust and fingerprints.
Over the years there have been many improvements.
Most manufacturers have resolved coating issues,
and additional hydrophobic coatings have been added
to keep lenses clean longer and make them easier
to care for. AR has become the option of choice for
any lens wearer who wants to look their best and
have optimal vision.

All
AR Lenses are Not Equal
Until now, a byproduct of AR coatings
has been a residual greenish or bluish color cast.
These color casts not only detract from the wearer's
appearance, they also reduce the transmission of light
to the eye. Optima's new patent-pending AR coating
process leaves the lens totally devoid of color.
Light reflections, if any, are greatly minimized.
This gives the wearer huge cosmetic benefits, as their
eyes are clearly visible and the increase in light
transmission allows more light to reach the eyes
so vision is also greatly improved.
A Patent-Pending
Hydrophobic Coating Layer Offers Impressive "Wearability"
Another proprietary patent-pending
process fills in the microscopic hills and valleys
that make up the hydrophobic oleophobic coating layer
to create an ultra-smooth surface with high surface
dirt and smudge resistance. In fact, Optima’s
new hydrophobic coating is one of the highest-rated.
The wearer benefits from lenses that stay clean longer
and are effortless to maintain.
