“CR dimming lens We use a plastic dimming lens made of high quality CR-39.  When exposed to the sun's rays, it changes from light brown to dark gray in 30 seconds.  It is a full-fledged all-weather lens that is stronger and weighs half as much as glass, provides an excellent fit, blocks harmful ultraviolet rays, protects the eyes, and maintains visual stability.”

“Characteristics of "Attiva" photochromic lens * In cloudy or foggy weather, the light brown color absorbs excess blue light (460-a 490nm) and gives 60 brightness to the eyes.  Under the shining sun, it turns gray and absorbs the orange spectrum (590-650nm), reducing glare.  00 Attiva ATTIVA 0P 02 01 00 Liquid length: Nanometer (nm) 00S 009 008 Display based on the Household Goods Quality Labeling Law Precautions for use: Sunglasses Lens material: Plastic (CR 39 dimming) * Suitable for face  Make sure to use the one that suits you.  * When purchasing, consult with a doctor or eyeglass shop about the material of the frame: lens frame material, material of the vine, visible light transmittance: 60% to 20%, nickel-copper alloy suitable for nickel-copper alloy.  Do not leave it in a hot place or mix it with metal that could damage it.  SU-7001”
