Presto we are making life easier for you whilst your training in different light conditions!
WHAT ARE AND HOW DO PHOTOCHROMIC LENSES WORK?
Photochromic Lenses look like regular transparent lenses when indoors but they automatically darken when moving into a brighter area. What happens is that UV rays from the sun do affect the lens molecules in the photochromic lenses so they change colour. They will darken in the light even on overcast days as UV rays still penetrate clouds. For example if you are requiring Cycling Sunglasses and training early in the mornings like many before going to work and its very dark the lenses will be complete clear, it's like you have nothing on your face! When the sun comes up or there is an increase in UV light then the photochromic lenses starts to darken. One sports sunglass lens for all conditions.
Photochromic Lenses can provide you with the best vision in all lighting through different shades of tint, without you even needing to think about it. Another name for for photochromic lenses is "Transitions' is the most well-known brand of photochromic lenses, but they generally have only one way to activate and that is via direct t UV light whereas Rudy Project Impactx lenses activate via UV light PLUS light - its a two way activation which makes them react faster and works better in altitude and humidity when compared to transition lenses. Photochromic lenses can also be referred to as adaptive lenses, auto-tinted lenses or variable-tint lenses. It's important to remember that Photochromic glasses are not to be confused with polarised glasses (sunglasses). These polarized lenses are anti glare but they aren’t changeable in terms of photochromic; they don’t adapt to light in the same way photochromic lenses do.

HOW DO THEY WORK?
Regular sunglasses block out particular wavelengths of light with either coloured filters or polarisation. As photochromic lenses are carbon-based, the molecules react to UV; they change shape and absorb the light, meaning the lenses start to look darker. The more UV rays there are, the darker the lenses will become. They adapt accordingly from clear through to different darker shades, depending on the levels of UV. The darkening can take up to 30 seconds for the tint to take effect on the glasses, and it can take between two to five minutes to return to normal when going back indoors.
They protect from UV rays, which helps your general eye health. Made from either plastic, glass or polycarbonate, photochromic lenses are available as different prescription glasses for people who have eyesight difficulties. Plastic photochromic lenses are often favoured over glass due to their molecular make-up; users often find the tint on plastic lenses to be more evenly distributed than on photochromic glass lenses.
WHO WORLD USE PHOTOCHROMIC LENSES?
