Photochromic sunglasses

How do photochromic sunglasses work?

A good demonstration is better than a long speech, here is a video that clearly shows how photochromic sunglasses work. By stimulating the lens with a UV lamp, the photochromic lens automatically darkens then completely lightens again in a few minutes.

The reaction here is deliberately amplified and accelerated. During standard usage, this phenomenon happens automatically without any noticeable change, and it is this gradual adaptation that makes these glasses so comfortable. But where you can really see the effectiveness of this technology is when you put them on in the morning and take them off in the middle of the day. The glare is then intense and unpleasant, although there was almost no noticeable increase in brightness.

Why wear photochromic lenses?

Developed in the 1960s, the mineral photochromic lens automatically reacts to the sun, or rather to UV rays, and has the particularity of darkening or lightening on its own depending on the ambient light. The plastic photochromic lens is more recent and dates from the 1980s. This type of sunglasses allows you to enjoy optimal vision even if the weather changes during the day or if you move into the shade for a few moments.

What are the benefits of photochromic sunglasses?

Photochromic sunglasses have the ability to adapt to ambient light or rather they adjust their tint to stabilise the amount of light transmitted as much as possible. The eye works less, and visual comfort is maximised. It's truly amazing to start a climb in the woods in the morning and to finish on a glacier at the end of the day without realising the change in light intensity. Photochromic sunglasses are also very interesting on white out days because even if the weather is completely overcast, the brightness can quickly become dazzling if the sun is not far above the cloud layer. Simply put, once you get used to this technology, it's hard to go without.

Skiing, cycling, running, photochromic technology at the service of sport

Skiing, cycling, and trail-running means being exposed to a variety of changing light conditions. Photochromic sports glasses are your ally, automatically adjusting to light conditions to provide an optimal visual experience at every moment.

Clarity for skiing

On ski slopes, visibility can change rapidly depending on the weather and topography. Photochromic lenses guarantee that you have clear, glare-free vision, regardless of the environment. From sunny laps to descents in the shade of fir trees, your glasses instantly adjust for maximum safety and performance.

Cycling without compromise

Cyclists appreciate the versatility of photochromic sunglasses, especially during long rides where sun exposure can vary considerably. The lenses adjust quickly to provide a clear vision, reducing eye strain and improving concentration. Additionally, UV protection remains constant, no matter the tint of the lenses.

Running with ease

For runners, the lightness of photochromic sunglasses plays a crucial role. Comfortable and fitted, they allow you to fully concentrate on your stride without being bothered by constant adjustments. As the weather changes during your run, your glasses harmoniously adjust to maintain optimal vision.

What is the price of photochromic lenses?

The price of photochromic sunglasses generally ranges between £85 and £170. This complex technology requires more complicated manufacturing processes, which significantly increases the cost of lenses. But the great advantage of this technology is that with a single well-chosen pair of sunglasses, you can cover almost all possible conditions. City, sport, beach, mountain, or even high altitude, you will never again wonder which sunglasses to take.

Photochromic sunglasses, what to choose?

While there are not really any models that outclass the others, some brands stand out like Julbo and Serengeti who have perfected photochromic technology for many years. Their photochromic lenses are tested and reliable over time and will offer you impeccable visual quality. You just have to choose the most suitable protection range for your needs.
