Transitions lenses contain special patented photochromic dyes that cause the lens to activate, or darken, when exposed to ultraviolet rays from sunlight. When the UV light diminishes, the lenses fade back. As light conditions change, the level of tint adjusts, offering the right tint at the right time.

How long does it take for transitions to change?
How fast do Transitions lenses work? Transitions lenses begin to darken the moment they are exposed to the sun’s UV light, reaching 70% tint within 35 seconds. When UV rays are no longer present, the lenses immediately begin to fade back, achieving 70% clear in just a few minutes.
Do transitions really work?
Cost effective – Photochromic or transitional lenses can actually be quite cost effective.Protects your eyes – Transitional lenses do more than function as sunglasses. They actually filter out a good deal of the harmful UV rays emitted from the sun, leading to healthier and happier eyes.
Are transition lenses bad for your eyes?
Aside from the sun, transition lenses offer protection against other light sources that may damage the eyes. This includes harmful blue light from screens and various devices. The exposure is also associated with migraines, photophobia, eyestrain, fatigue, and squinting.
How do you activate transition lenses?
Transition lenses are activated when exposed to sunlight. The stronger the sunlight the darker the lenses will get. However, remember that any glass (like a car windshield, window, etc.) can absorb UV rays and the lenses might not darken as much as when you are outside in direct sunlight.
Do transitions block blue light?
Transitions® lenses protect your eyes from harmful blue light both outdoors and indoors.Transitions® Vantage™ lenses filter 35% of harmful blue light indoors and 85% outdoors.
Do transition lenses turn yellow?
Transition lenses don’t change behind the windshield of a car. When Transition lenses do wear out, they will take on a yellowish tinge when they’re clear. They will no longer get as dark at that point. Transition lenses don’t get as dark as standard sunglasses.
How long do transition lenses take to go clear?
They typically take around 30 seconds to fully darken and between two to five minutes to return to a clear state.
Why do my transition lenses stay dark?
When it is colder outside you may notice that your Transitions lenses seem to get darker than they do when it is warmer. This is because the molecules move more slowly when they are cold, which means when they are cold they will fade back from dark to clear more slowly.
How dark can transition lenses get?
Transition lenses do not get as dark as typical sunglasses lenses, and they do not darken much behind the windshield of a car. They also get darker in cold weather than in very hot weather. You can add transition lenses to any pair of glasses.
Can you wear transition lenses at night?
Yes. They can be worn any place that you would wear regular clear lenses all day, every day. Transitions lenses help you see more comfortably inside and out, day and night.
What are the drawbacks of transition lenses?
Cons of transition lenses
- They darken and lighten to varying degrees depending on the brand. Some lenses also take longer than others to adjust to brightness.
- These lenses can take longer to adjust in cold weather.
- They don’t darken as well inside cars.
Can you drive with transition lenses?
Answer: Photochromic lenses work in UV light, which most car windscreens block out. As a result, they tend not to react as quickly in a car as they would normally. Tinted glasses, lenses or visors should not be worn at night or in poor visibility, but are fine to use in good driving conditions.
Should you put transition lenses in the freezer?
Photochromic lenses take longer to turn from dark to clear than from clear to dark. If you receive photochromic lenses that don’t seem to be working, put them in the freezer for 10 to 15 minutes and then take it outside in direct sunlight. This should activate them and should make it work.
Do I need to break in transition lenses?
Transitions lenses do not need a break in period. Regardless of color, all that is needed is UV exposure to start the reaction.
Does temperature affect transition lenses?
All Transitions lenses are temperature-dependent. Temperature affects the degree to which your lenses darken and the speed with which they clear again.At very high temperatures, Transitions Lenses will not be as dark due to the thermal process affecting the molecules. This is a normal reaction for photochromic lenses.
Do transition lenses help astigmatism?
Who can wear ACUVUE® OASYS with Transitions™ contact lenses ? This contact lens is for anyone who is far or near sighted or anyone looking for light management benefits, including those who do not require vision correction. This product is currently not available for people with astigmatism or presbyopia.
Do transition lenses have anti glare?
Yes. Transitions lenses are compatible with anti-scratch and anti-fog coatings. And not only are they compatible with anti-reflective coatings (which reduce reflections off the lenses), but Transitions lenses are even better in reducing distracting, discomforting, and disabling glare, both indoors and out.
What is Bluelight?
What is blue light? Blue light is part of the visible light spectrum — what the human eye can see. Vibrating within the 380 to 500 nanometer range, it has the shortest wavelength and highest energy. About one-third of all visible light is considered high-energy visible, or “blue,” light.
Why glasses become yellow after a period of time?
When an originally clear lens begins to take on a yellow tint, it is generally considered to be a sign of age-related wear and tear. There are several reasons given for this change. In particular, this sort of yellowing is attributed to exposure to sunlight.
Can you remove transitions from glasses?
Rub the lenses with a microfiber cloth to remove the coating. Use a microfiber cloth so you don’t scratch the surface of the lenses. Hold the glasses in 1 hand and use your other hand to hold the cloth and gently rub the lenses using consistent, circular motions to remove the compound as well as the coating from them.
