Photochromic lenses


The tint of the lenses varies in accordance with the degree of luminosity

Photochromic lenses are lenses that become darker or lighter depending on the intensity of the luminosity outdoors. Photochromic lenses become darker or lighter depending on the degree of UV-rays you are exposed to. Outdoors, the darkest tint may vary according to the temperature.

These glasses can be worn indoors as well as outdoors and will protect your eyes against harmful UVA- and UVB-rays, which are invisible but very much there, even when there is almost no sun. Your visual comfort will be outstanding thanks to the brighter view these glasses provide you with.

A photochromic coating can be applied to every pair of prescription glasses (unifocal as well as progressive). Like all tinted lenses, photochromic lenses are not comptable with the thinnest lenses (index 1,74). You have the choice between two colours: brown and gray.

Glasses24 proposes photochromic lenses with a range of 0 (tinted at 10%) to 3 (tinted at 85%, ensuring a solid protection from the sun).


Best protection

It is of vital importance to take good care of your eyes. UV-rays are invisible but very much present, even when the sun is not out. They increase the aging of the cornea. Photochromic lenses offer a distinct UV-protection that adapts on its own to the weather conditions and allows you to protect your eyes in the long run. Nonetheless, you also damage your eyes if you impose a protection that is not or maladjusted. For example, wearing sunglasses when there is little luminosity, can heighten the sensitivity of your eyes to the light. With photochromic lenses, you avoid damaging your eyes, because they automatically adapt in accordance with the luminosity, while your eyes will not have to do the effort.

Visual comfort guaranteed

Blinking and squeezing your eyes when you go out under the sun, is in the past now. These lenses adjust when you go outdoors and re-adjust when you go inside, or get in the shade. Perfectly clear indoors, they will only adapt their tint when you go out and when you go from the shade into the sun, if the sky is clouded or sun-lit. Under any circumstances, these lenses provide you with the best anti-glare protection. You will feel a substantial relief when wearing these glasses, since they, whilst protecting your eyes, also give your eyes a well-deserved rest.

Using multiple glasses, you know the feeling? Always having your sunglasses at hand, when the sun is blinding you, forgetting to take them off when you go home and find yourself in the dark? That lies in the past. Thanks to photochromic glasses, you only have one pair that can serve as your daily glasses and as your sunglasses. It is easy and efficient because the lenses adapt automatically to the degree of luminosity you are exposed to. You do not have to think about it. This technology is also very handy if you do a lot of sports or outdoors activities.

Classic sunglasses for driving

The only flaw of photochromic lenses : driving your car. The windshield reduces the transmission of UV-rays and the lenses will not tint when you are driving, which leaves your eyes unprotected. The sole solution we have today is to keep a pair of sunglasses in your glove compartment.
