How do Transitions
work?
Transitions Lenses contain
special photochromic dyes that cause the lens to darken when
exposed to ultra-violet rays from sunlight. When the ultra-violet
light diminishes, the lens becomes clear again. This photochromic
effect comforts the eye and makes Transitions Lenses the right
lenses in any light.
Are Transitions Lenses
an alternative to clear lenses?
Yes, because
Transitions Lenses are the ideal all-around lenses. While they are
clear indoors, they adapt to any light condition when exposed to
sunlight outdoors. In addition, they provide automatic UV
protection, blocking 100% UVA and UVB rays. Transitions Lenses are
also available for all types of prescriptions, from single vision
to progressives, and are compatible with all frame styles.
How fast do Transitions
Lenses work?
Transitions
Lenses begin to darken the moment they are exposed to UV light. The
degree of darkening is a function of the intensity of UV light. The
instant UV rays are removed, the lenses begin to clear. In short,
this means that Transitions Lenses quickly darken when you go
outdoors, and quickly lighten when you return indoors. Most users
report that this transition happens so smoothly, they are unaware
of the change. They are aware, however, of their continued visual
comfort.
Why is UV protection
important?
Most of us make
a point of taking all the necessary precautions to protect our skin
against ultraviolet rays. But, although we are rarely aware of it,
our eyes also demand protection against UV damage. We are all
exposed to harmful UV rays, and, over the long term, these rays
significantly contribute to the deterioration of our eyesight. We
at American Vision Care therefore now recommend that people protect
their eyes against UV exposure at all times. Transitions Lenses
provide 100% protection against UV rays.
Can I use Transitions Lenses like
sunglasses?
In most outdoor
conditions, Transitions Lenses are perfect for reducing the sun's
glare. They actually lighten and darken as the sun goes in and out
of the clouds. However, since extremely high temperatures tend to
affect lens performance, Transitions Lenses may not always get as
dark as sunglasses. Ask your eyecare specialist for advice.
Are Transitions Lenses suitable for
driving?
In a car,
Transitions Lenses darken much less than they do outside because
the windshield blocks most of the UV rays that cause the lenses to
darken. Ask us at American Vision Care if you need a pair of
prescription sunglasses for driving.
Where can I purchase Transitions
Lenses?
Transitions

Are Transitions Lenses available
in different lens designs?
Transitions
Lenses are available in a wide range of lens designs including
Single-Vision, Bifocals and Progressives. They are also currently
available in two different colors: gray and brown.
Can Transitions be worn while
working on a computer?
Transitions Lenses are perfect for this type of activity. In any
situation where you’d wear regular lenses, Transitions can be worn
to help you see more comfortably whatever you’re doing.
