For instance, since extremely high temperatures can affect lens performance, Transitions lenses may not always get as dark as sunglasses. Also, since they are activated by UV exposure, most Transitions lenses don't work behind the windshield of a car (your windshield actually blocks UV rays).
How do you make transition lenses stay dark?
Put them in your freezer for 15 minutes. Take them out, put them in the sun for a few good minutes, let them get good and dark. Something about chlling them first activates more of the chemical in the lens, thus producing deeper tint ever after.
How long does it take transition lenses to darken?
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.
How do you test transition lenses?
When in contact with UV light, the photochromic particles are activated in 20 to 30 seconds. If you're not sure, cover one of the lenses with your hand, then put the sunglasses on, wait 20 to 30 seconds and check the difference between the activated and non-activated lens.
How do you make transition lenses change faster?
If you move into a shaded area outdoors, they will stay darker longer than they would on a warm day. When you move into a shaded area when the temperature is warm outside, the molecules will be quicker to respond to the reduced UV and they will begin to lighten up more quickly.

Does putting transition lenses in the freezer help?
A There is no truth in this old wives tale! Some photochromics will appear darker, or even too dark, in cold temperatures due to slower opening and closing of the photo-chromic molecules, but storing your lenses in the freezer will not enhance performance or life span.
Why do transition lenses get darker in cold weather?
The molecules in photochromic technology work by reacting to UV light. However, temperature can have an effect on the reaction time of the molecules. When the lenses become cold the molecules begin to move slowly. This means that it will take somewhat longer for the lenses to adapt from dark to clear.
