Optical coatings include diamond-like carbon (DLC) and anti-reflective-scratch hybrid coatings. Diamond-like Carbon ...
These safety sunglasses have a scratch resistant coating, block 99.9% UV, and meet ANSI Z87.1 and CSA Z94.3 standards. The only way to assess the protection of sunglasses is to have the lenses measured, either by the manufacturer or by a properly equipped optician.
A wide range of colors can be achieved by dyeing of the surface or the bulk of the material. CR-39 is also resistant to most solvents and other chemicals, gamma radiation, aging, and to material fatigue. It can withstand the small hot sparks from welding, something glass cannot do. It can be used continuously in temperatures up to 100 °C and ...
