1. Optically tempered glass with a hardness of 9H. Optically tempered glass is about ten times harder than plastic lenses. Plastic typically has a surface hardness of 1H, while tempered glass reaches 10H, making it scratch-resistant and more durable than plastic lenses. It also offers improved light transmission. 2. The lens material has a light transmittance of nearly 92%, and an AR coating increases this to over 98%. 3. The lens is coated with a water-repellent coating, achieving a drip angle of 115 degrees, preventing water droplets from remaining on the lens surface and affecting the shooting quality. 4. Snap-on mounting for easy installation and removal. Material: Optically tempered glass with an anti-reflection, anti-fog, and anti-water coating, then hardened. Functions: Anti-scratch, anti-fog, waterproof, dustproof, anti-deformation, and high-temperature resistant. Hardness: 10H Lens Material: Optically tempered glass Light transmittance: 99% Due to different batches, there may be differences in product appearance, color, and printed text, which will not affect the use.
