By definition, a photochromic product (from the Greek photôs light and chromos colour) is made of pigments or dyes whose optical qualities change in response to light, much to the way that sunglasses lenses change from translucent to dark when exposed to sunlight.
Among other plastics, polycarbonate is a common material for photochromic lenses. Glass lenses darken by absorbing visible light.
They are primarily employed in glasses that are dark in direct sunlight yet transparent or, less frequently, softly tinted in less lit environments.
When exposed to light with a high enough frequency, most frequently UV radiation, an optical lens known as a photochromic lens darkens.
The lenses return to their clear state when the activating light is not present. Polycarbonate or another type of material may be used to create photochromic lenses.
The Global Photochromic materials market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The Next Generation of Photochromic Lenses from ZEISS PhotoFusion X lenses offer a higher level of integrated blue light and UV protection while darkening and clearing more quickly.
Instead of needing to switch between two pairs of glasses—one clear and one dark, suntinted pair—when going from indoors to outdoors, there might be one pair of glasses for all lighting conditions.
Photochromic lenses have long provided that service. The next generation of photochromic lenses, called ZEISS PhotoFusion X, is built on a brand-new photochromic mechanism.
Transition speed has greatly increased with this restart.Additionally, a new base lens material offers complete blue light shielding indoors and out.
Countless photochromic dyes in light-reactive lenses start to alter shape when they are exposed to UV radiation. The glasses’ lenses darken as a result of this response.
The most recent ZEISS PhotoFusion X lenses employ an entirely new photochromic system with quicker dyes in a sturdy yet more open carrier matrix.
In terms of percentages, this means that ZEISS PhotoFusion X lenses darken up to 60% quicker than ZEISS PhotoFusion prior generations.
Fast lens clearing is crucial for many spectacle users when going from the outside to the indoors. To make this process better, extra effort was taken.
