Transitions - FAQ's
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 100% UV protection. 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. Most eyecare professionals 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 less than they do outside because the windshield
blocks most of the UV rays that cause the lenses to darken.
Ask your eye care professional to explain and demonstrate what Transitions do
behind the windshield.
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.
