1. Learn About Lenses that Transition From Stanton Optical
Are you shopping for a new pair of prescription glasses? Are you interested in various lens
upgrades but aren’t sure what your options are. Have you ever considered lenses that
transition? Transitional lenses, popularized by Transitions Optical, Inc. in the 1990’s, are
more correctly called photochromic or photochromatic lenses. Many lens vendors
manufacture their own brand of photochromic lenses.

Lenses that transition are very popular especially with people who spend a lot of time
outdoors. Photochromic lenses offer a good compromise between having to constantly
switch between regular eyeglasses and sunglasses every time you go outside. Lenses that
transition gradually get darker when exposed to sunlight and adapt from clear to dark and
every shade between the two extremes.
High Technology Eyeglasses
2. Photochromic lenses, invented by Roger Araujo at the Corning Glass Works, have been
around since the 1960’s. They come in lightweight plastic, glass or impact-resistant
polycarbonate versions. Photochromatic eyeglass lenses have a special sun activated
coating. It is exposure to UV rays that causes the glasses to change colors, that’s why they
don’t darken when you are indoors under artificial light.
The lenses are embedded with microscopic crystals of either silver halide or silver chloride.
The chemicals stay clear in the presence of artificial light but darken when exposed to UV
light. There are a few problems associated with photochromic lenses. Some people
complain that the lenses don’t get dark enough on really sunny days, they take too long to
switch back to clear when returning indoors and they have problems transitioning in
extremely hot or extremely cold climates.
Advances in Photochromic Lenses
Your car’s windshield blocks out most UV light causing the lenses to stay clear and not
darken, but the newer styles of photochromic lenses are supposed to solve that problem.
Recent technological advances have solved most of these problems with certain
photochromatic lens manufacturers making a style of lenses that darken even when you
are driving in your car.
Lenses that transition enhance your vision as they help reduce eye strain and fatigue. They
help protect your eyes from the glare of sunlight reflecting off of surfaces such as sand,
snow or water making them the perfect choice for an active lifestyle. Excessive exposure of
your eyes to the sun may be a leading cause of cataracts, macular degeneration and other
age-related eye diseases. Hikers, cyclists, runners, golfers and other outdoor enthusiasts
can all benefit from photochromic lenses. Many brands of lenses that transition block 100%
of UVA and UVB light. Photochromatic lenses are also available with a polarized coating for
added glare protection.
3. Lenses that transition can be made in bifocals, progressive, trifocals or single-vision type
lenses depending on your exact prescription needs. And did you know that photochromic
lenses are available in both prescription and non-prescription versions? So you don’t need
to wear RX lenses to enjoy all the great benefits of lenses that transition.
Photochromic Lenses for Athletes
Many runners and cyclists like to wear glasses to protect their eyes from wind and flying
debris, even when it’s dark out. Photochromic lens sunglasses are the perfect solution for
sports fans. It used to be that athletes purchased sunglasses with multiple lenses and
switched to whichever lens they needed depending on the ambient light conditions: clear,
yellow, light gray, rose or black.
Lenses that transition can also be tinted for specific situations. Yellow, gray and rose tints
are often used by athletes such as cyclists, runners and triathletes. The lenses fade to a light
color, depending on the tint used, and darken like regular photochromic lenses when
exposed to sunlight.
