Sun outside, artificial lighting and radiation from monitors inside. Constantly changing light conditions are often a big problem for people with prescription glasses. But where there is a problem, EssilorLuxottica comes with its most modern technological solution - Transitions® Light Intelligent Lenses™ self-tinting lenses! Why is it worth choosing them?

In the previous article, we talked about photochromic (self-tinting) glasses - these are glasses that change the color of their lenses depending on whether you are in direct sunlight or indoors. Without a doubt, this is the most convenient way of protecting and correcting vision in one.


How do self-tinting glasses work?

The self-tinting process of photochromic glasses is automatic and fast. When the glasses are exposed to sunlight, the photo-reactive chemicals in the lenses react to the ultraviolet radiation. This process causes the glass to become darker to protect the eyes from unwanted glare and the harmful effects of UV rays. When the surroundings are less illuminated again, for example when transitioning to an indoor environment, the glass will slowly return to its transparent state. Darkening takes about 30 seconds, then returning to a clear state takes about 5 minutes.

There are many types of self-tinting glasses on the market, but we always want to bring you the best. That is why on eyerim you can find self-tinting lenses from the global optical giant EssilorLuxottica called Transitions® Light Intelligent Lenses™. How are these glasses different? Let's take a look at it.


1) Transitions Signature GEN 8®


These adaptive glasses, already in the 8th generation, are designed for normal everyday wear. They are clear in the interior, but they darken when exposed to UV light. They provide 100% UV protection and are available in 2 colors: brown (increases contrast) and gray (neutral, supports correct color vision).


2) Transitions XTRActive®

If you are very sensitive to light or frequently exposed to bright light, the new generation Transitions XTRActive® glasses are designed for you. These are the darkest self-tinting glasses with extra protection against intense light, which are also suitable for drivers. They provide 100% protection against UV radiation and reliably filter up to 34% of blue-violet light indoors and up to 90% of blue-violet light outdoors. These glasses in the interior remain with a gentle protective tint, which, however, has no effect on your vision. The great news is that the transition from dark form back to clear is up to 35% faster than other lenses.

Testing on spectacle wearers has shown that in many situations – such as driving, strong daylight, time spent indoors in front of a screen or exposure to artificial light – users prefer the new generation of Transitions XTRActive lenses.
