Automatic light adjusting lenses
As well as picking the colour of your frames now you match the colour of the lens so you can adjust for various fashion styles.
Increasingly more young, stylish and edgy glasses wearers are trying
Transitions lenses. And they are loving them.
With seven Transitions Signature colours to choose from – including four bold Transitions style colours – wearers can now pair lens colours and frames to create their own bold and individualised look.
They darken and lighten to varying degrees depending on the brand even with temperature and some don’t darken as well inside cars. Originally glass lenses were the only material choice and grey lenses the only colour in the 1960’s. Transitions brought the first plastic transtions lens to market in 1991 and 2020 will see the 8th generation of continuous performance improvement.
Generation 8 lenses get darker and become clear again quicker — three minutes less for fade back than Transitions Signature lenses with Chromea7 technology and 30 percent less time for the lenses to activate.
The earliest glass photochromic lenses relied on silver chloride or silver halide to react to UV light and darken. Most of today’s photochromic lenses use proprietary dyes in the surface layer that undergo chemical changes that darken the lenses when exposed to UV light.
Now often times you wear just these and dont have to carry a clear and a sunglass pair with you.
