Transition Lenses
[b]Lens[/b]Transitions is positively a brand name of a Photocromic Lens. Although transitions are probably the most advanced photochromic lens on the market there are many others out there.
People call Photochromic lenses by all distinct kinds of names such as Transitions, Reactolite, Reactions and I've even heard them called Graduations. However, they are all Photo chromic lenses.
Photochromic lenses are clear lenses that react with Uv and produce a tint ensue based on the number of Uv present.
When wearing Photochromic lenses even a dull day some reaction will occur producing a very pale tint and then on a very intriguing day where more Uv is gift they will turn quite dark. When wearing them indoors they will become clear.
The idea behind photochromic lenses is that they will contribute the literal, number of safety for the varying light conditions you experience. However, when driving, your car windscreen will block a obvious number of Uv which is required to make the lens react so they will not work as well as they would exterior of the car.
The Two Most common Photocromic Lenses
Transitions Lenses
Transitions are available in suitable Plastic, Poly Carbonate, 1.6 and 1.67 Lenses. They are the fastest reacting lens on the market and will react into sunglasses within 30 seconds. However, they will take longer than that to go clear again when you go inside.
Reactolite Lenses
Reactolite is a brand name given to a Glass photochromic lens. They do not react as well as the transitions and are much heavier to wear. However, one good thing about glass reactolite is that they work much better behind a car windscreen than the transitions do. (If only we could have the best of both worlds.)
In most cases the Transitions lens is the adored choice due to the over all comfort and performance.
Photocromic lenses are ideal in the sense that they can save you having to purchase two pairs of glasses ie, Clear glasses and a pair of Sunglasses. However, many people who wear transitions also have a economy tinted pair just to use in the car.
