There are pros and cons of photochromic lenses and sunglasses, including those listed below:. Reaction Times — Although photo lenses reaction from clear to sunglasses is quite quick, typically within 30 — 60 secs, the reversal takes a little longer as much as 5 minutes depending upon the temperature of the lens which could be dangerous if entering a dark room or certainly inconvenient at best. Photochromic Lens Temperature Dependency:.

Cold weather also increases the time taken to return to a clear shade. Plastic photochromic lens molecules of silver and halide are usually layered or embedded evenly onto the surface of the lens providing an even shade of tint when darkening. Glass photochromic lenses have the molecules contained within the glass and this can sometimes cause an uneven tinting effect on a lens with higher prescription due to the different thickness of the lens from one edge to the other.

Can I use Photochromic sunglasses for driving? Standard photochromic lenses do not work inside a car due to the windscreen blocking out the UV rays which are needed to active the chemical process which causes the lens to darken.

A new lens has been brought to the market that can react inside a car or behind the windscreen without UV rays and uses daylight alone to trigger the reaction. These lenses are known as ' transition drivewear lenses ' which combine both photochromic and polarisation technology. As the name suggests, they were invented for use in the car whilst driving and offer full protection from the suns glare during the day which makes them perfect for wearing whilst driving.

The trillions of sunlight-sensitive molecules in every photochromic lens change shape and structure when exposed to UV radiation. As a result, they can absorb visible light, so the eyeglass lenses darken. The chemical process that changes sunlight-sensitive lenses from light to dark and vice versa is also affected by factors such as temperature.

The molecules inside the lenses move and change shape more slowly in colder temperatures, whereas light sensitive lenses may adjust their tint more quickly on scorching days.
