The basic idea behind the Photo chromic lenses is that they should provide protection against the harmful UV rays of the sun and also from the changing effect of the sunlight which can be harmful for our delicate eyes.

These lenses can produce a tint effect depending upon the amount of UV rays falling on them. The tint effect is more on a bright sunny day as the UV rays present are more and less on a dull day as the UV rays present is much less. They do more than ordinary clear lenses as they adjust automatically to changing light thus controlling the light falling on eyes and hence allow the wearer to see comfortably in any intensity of light. They will act as clear lenses when you are inside or when it is night but when you are in sun light they will turn as dark as sunglasses.

There are various names given to these Photo chromic lenses such as Transitions, Reactolite, Reactions and Graduations. But in totality these lenses are known as photo chromic lenses. The photo chromic lenses from Transition are the most advanced lenses and in most cases the Transitions lens is the preferred option due to their over all comfort and performance.

Transition lenses are available in various forms such as in Standard Plastic, Poly Carbonate etc. These lenses are made from very advanced technology and are the very fast to react to the UV rays of the sun. They take not more than 30 seconds to react and it is within this short span of time that they even get clear. Reactolite is another brand name of glass photo chromic lenses. But these lenses take a longer time than the transition lenses to react and are much heavier.
