The
Chinese began using colored lenses in eyewear
in the 1300s, where Chinese judges sometimes
wore smoke colored quartz crystal lenses to
hide their eye expressions in court. A judge's
evaluation of evidence as credible or not
was to remain secret until a trial's conclusion.
In the 1400s, the Chinese also introduced
the concept of smoke tinting to darken eyeglasses.
Like earlier quartz lenses, darkened lenses
did not correct vision nor were they initially
intended to reduce solar glare. Vision correcting
darkened lenses also made their way to China,
but this time via Italy where that particular
innovation originated.
In
the 18th century, James Ayscough began experimenting
with tinted lenses in spectacles, but the
purpose still fell short of the purpose of
modern sunglasses; Ayscough believed blue-
or green-tinted glass could correct for specific
vision impairments. Protection from the sun
was still not a concern. Modern sunglasses
that are used to block the damaging UV rays
of the sun (and to look cool!) were first
introduced in 1929 by Sam Foster, founder
of the Foster Grant sunglasses company. He
first sold his new Foster Grant sunglasses
on the Boardwalk of Atlantic City, NJ, and
by the early 1930s sunglasses had become the
new "must have" fashion accessory of the times.
In
America, the U.S. military, which had already
played a key role in the development of more
advanced sunscreens, was also the impetus
for advances in UV protection in sunglasses.
In the 1930s, the U.S. Army Air Corps commissioned
optical specialists Bausch & Lomb (B&L) to
produce a type of sunglasses that would protect
pilots from the dangers of high altitude glare.
In pursuit of that goal, B&L physicists and
opticians perfected a special dark green lens
tint that absorbed light in the yellow band
of the spectrum. This advance led to the introduction
of polarized sunglasses, a technique used
to block harmful UV rays from the sun and
first introduced by B&L Ray-Ban in 1936. While
B&L introduced other design advances in house,
the specific polarization innovation they
used was licensed from Edwin H. Land of Polaroid
camera fame. Polarization is not the only
approach to protecting the eyes from harmful
sunlight; you can read our thoughts on other
techniques and the positives and negatives
associated with them on our Polarized Versus
Non-Polarized Sunglasses page.
These
new B&L became known as aviator sunglasses,
featuring a slightly drooping frame perimeter
to maximize the shielding of an aviator's
eyes. This was both effective and practical,
for fliers routinely glanced down toward the
plane's instrument panel. Fliers were issued
the glasses at no charge by the military,
but in 1937 the general public was able to
purchase the model that "banned the sun's
rays" and became known as Ray-Ban aviator
sunglasses.
Since
the 1950s, sunglasses have become one of the
most popular fashion accessories in the world,
stylish and yet practical. Blogs and celebrity
sites track and report on the sunglasses worn
by celebrities, and more and more these are
becoming vintage styles from industry leaders
like Revo, Ray-Ban, Carrera Oliver Peoples,
and Oakley. In fact, a number of famous names
