Photochromic lenses are lenses that darken on exposure to specific types of light,
most commonly ultraviolet (UV) radiation. Once the light source is removed (for
example by walking indoors), the lenses will gradually return to their clear state.
Anti-Reflective (AR) coating improves the transmittance of light, reduces reflection
from lenses, and eliminates stray lights. It is highly recommended for a clear night
time vision.
High-vacuum electron beam evaporation, to effectively prevent the radiation of electromagnetic
radiation and electrostatic damage to the glasses.
UV coating blocks up to 99% of rays up to 400nm protecting the eyes from radiation
while not interfering with visible light.
A layer of coating that prevents scratches from occurring on the surfaces of lenses
from daily use.
Hard coating forms a permanent bond with the surface of the lens that prevents heavy
scratches from occurring on the surface of the lens.
