10H Tempered Scratch-Resistant High-Grade Optical Glass Protective Lens 1. Made of optical tempered glass with a hardness of 10H. Optical tempered glass is about ten times harder than plastic protective lenses. Plastic surfaces typically have a hardness of 1H, while tempered glass reaches 7H or higher. Its scratch-resistant, more durable than plastic protective lenses, and offers better light transmission. 2. The lens material has a light transmittance of nearly 92%, 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 115 degrees, preventing water droplets from remaining on the lens surface and affecting shooting results. 4.
