What are photochromic lenses?

Photochromic lenses are dynamic lenses that have the ability to darken when exposed to sunlight and UV radiation. They return to their original, "transparent" state when indoors. With their photochromic properties they regulate the appropriate amount of light entering the eye, resulting in clear and relaxed vision while offering maximum protection from blue light and UV radiation. UV radiation is one of the most damaging challenges to long-term eye health. UV radiation is always present. All year round, all day, winter and summer, in sunny or cloudy conditions. Although it is invisible, long-term exposure can cause serious damage to the eye and surrounding tissue.

Sunlight contains 2 types of harmful wavelengths, UVA & UVB. UVA rays penetrate deep into the skin which results in aging the skin faster. UVB rays are mainly responsible for sunburns.

Excessive exposure to UV radiation is dangerous for your skin and eyes. It can cause very significant damage such as cataracts or macular degeneration. Prevention to avoid these effects is imperative.

Are photochromic lenses as transparent as conventional transparent lenses?

Yes, indoor photochromic lenses are as transparent as conventional lenses.

How dark do photochromic lenses get and how fast?

Photochromic lenses are as dark as conventional sunglasses with a maximum darkness of 95%.

Photochromic lenses darken instantly in about 30 seconds. The rate of darkening depends on the amount of uv present in the environment, the time and position of the sun.

The duration of discoloration of photochromic lenses indoors again depends on the presence of uv radiation and lighting. Approximately 6 to 10 minutes is the estimated time.

Photochromic lenses in the car

Because the car windscreen cuts off uv radiation, most photochromic lenses are not activated, but only a class of photochromic lenses containing a special photochromic formula that allows them to react not only to uv radiation but also to the blue spectrum of light.

Are photochromic lenses suitable for children?

Photochromic lenses are the ultimate choice for children, due to their lifestyle and the physiology of their eyes that are not fully developed, children are exposed to uv radiation at least 2 times more than an adult.
