1. Made with optical tempered glass, achieving a hardness of 9H. Optical tempered glass is approximately ten times harder than plastic protective lenses. Plastic surfaces typically have a hardness of around 1H, while tempered glass reaches 9H or higher! No more fear of scratches; more durable than plastic protective lenses, and offers better light transmission. 2. The lens material has a light transmittance of nearly 95%, with an AR coating layer that increases the light transmittance to over 98%. 3. The lens has a waterproof coating layer with a drip angle of up to 115 degrees, preventing water droplets from remaining on the lens surface and affecting shooting results. 4. It adopts a snap-on installation method, making installation and disassembly simple and convenient. 5.
