Material: Optical tempered glass, coated with anti-reflective, anti-fog, and anti-water films, and further hardened. Functions: Scratch-proof, anti-fog, waterproof, dust-proof, anti-deformation, and resistant to high temperatures. 1. Made of optical tempered glass with a hardness of up to 10H. The optical tempered glass material is about ten times harder than plastic protective lenses. The surface hardness of plastic is generally only 1H, while that of tempered glass can reach 10H or >10H! No longer afraid of scratches, it is more durable than plastic protective lenses and has better light transmittance. 2. The light transmittance of the lens material is close to 92%. After being coated with an AR coating layer, the light transmittance of the lens is increased to more than 98%. 3. The lens is coated with a waterproof film layer, and the water drop angle reaches 115 degrees. No water droplets will remain on the surface of the lens to affect the shooting effect. 4. It adopts a snap-on installation method, which is simple and convenient for installation and disassembly.
