The Science of Light Adaptation in 1.56 Photochromic Lenses

Ultraviolet excitation ‌ : under lighting conditions, photosensitive substances decompose or undergo structural changes (such as silver halide → silver + halogen), and the lens rapidly darkens ‌.

‌Restoration of transparency ‌ : After leaving the ultraviolet light, silver and halogen under the action of catalyst (such as copper oxide) to recombine into silver halide, lens restoration of transparency ‌.

The Benefits of Photochromic Technology in 1.56 Lenses

• Uv protection

  The lenses automatically change color according to UV intensity, block harmful UV and blue light, reduce glare irritation and eye fatigue, especially suitable for outdoor activities and high UV environment ‌.

• Multi-functional integrated design ‌

  Indoor anti-blue light (filter electronic screen blue light), outdoor second change sunglasses, no need to frequently change glasses ‌.

• High cost performance

  Compared with high refractive index lenses, the price of 1.56 is more advantageous.
