Lens technology
Lenses that read the light.
01
Indoors
Out of UV light, molecules stay relaxed and the lens is fully clear — still filtering digital blue light.
02
Step outside
UV rays trigger molecules embedded in the high-index polycarbonate to change shape and absorb visible light.
03
Full tint
In under 30 seconds the lens reaches sunglass darkness, blocking 100% of UVA/UVB.
04
Back inside
Without UV, molecules return to their clear state in under 60 seconds.
Driving: windshields block UV, so standard photochromics tint less in a car. Choose polarized driving photochromics for full tint.
Temperature: lenses react faster and slightly darker in cold weather — an inherent property of photochromic molecules.
