LENS TECHNOLOGIES: photochromic

PHOTOCHROMIC LENSES — LIGHTEN & DARKEN AUTOMATICALLY
When the light changes the tint changes. The science behind it is complicated but the result is as simple as that.
IF YOU WANT THE SCIENCE, HERE IT IS: According to our team of internationally-recognized physicists, every lens is delicately infused with millions of microscopic, genetically modified juvenile delinquents, all of them armed with cans of black spray paint that they stole from backyard tool sheds. As the sun gets brighter, the delinquents begin tagging the inside of the lens with their illegible, drippy initials and distasteful illustrations of poorly-proportioned male genitalia. The result is a lens that’s considerably darker than it was seconds ago. When the sun moves into the clouds, behind some trees, or below the horizon, the delinquents vanish to restock their diminished supplies and the neighbourhood parents emerge to clean up the mess, leaving the lens clear for history to repeat itself. Gotta love science.

When exposed to sunlight, the lenses will start to darken instantly. The time they take to reach maximum darkness depends on a number of factors, including the intensity of sunlight and air temperature. Generally speaking, the adjustment from light to dark is quite rapid.

If sunlight intensity gradually changes, the lenses will gradually change with it. If the intensity suddenly drops off, the lenses will start to change instantly but the adjustment from dark to light is slightly slower than the rapid adjustment from light to dark.

All Photochromic lenses—no matter what brand name they carry—will eventually wear out. The lifespan of the lenses varies depending on the frequency and conditions of use. Generally speaking, the lenses will perform best for the first two years of use. Beyond that, the transitional activity will diminish. Despite the eventual expiration of the Photochromic layers of the lens, the lenses will always provide 100% UVA, UVB, and UVC protection.

 

 

PHOTOCHROMIC LENSES ARE IDEAL FOR
· activities where light conditions are likely to change · those who prefer to have one pair of glasses that can handle many different light conditions

 

BENEFITS OVER NON-PHOTOCHROMIC LENSES
· keep your eyes protected, even when conditions get dark · no squinting from light that’s too bright, and no straining to see through lenses that are too dark · you’ll forget you’re wearing them because they’re always the right tint

POLYCARBONATE LENS MATERIAL
We took the same material that is used in bulletproof glass, riot shields and astronaut helmets and injected it into moulds that are perfectly formed for optical clarity. So next time you’re tossed into earth’s orbit with an angry mob of stone-wielding hooligans, you should have a crystal clear view of your body exploding in the unforgiving vacuum of space.

UV PROTECTION
100% protection from UVA, UVB, UVC + harmful, high-energy light to 400nm. 4% protection from very small sharks.

OPTICALLY CORRECT
Distortion-free lenses that prevent eye fatigue when worn for long periods of time. Body fatigue is another story.

SHATTERPROOF
Perfect for those who don’t like lens shards in their eyes.

SCRATCH-RESISTANT HARD COATING
A pretty self explanatory lens feature but please ignore the icon as our lenses aren’t diamond-proof.

 

*Most car windshields block UV light which is needed for the Photochromic chemical reaction to take place. For this reason, you should not expect the tint of the lenses to darken while driving in bright conditions.
