For Insta360 X4 Sports Camera Protective Case with Optical Glass Lens Protector

• This product uses optical tempered glass with a hardness of 9H. Optical tempered glass is about ten times harder than plastic protectors, which generally have a hardness of 1H, while tempered glass can reach 9H or even greater. This means it's highly scratch-resistant and more durable than plastic protectors, providing better light transmission
• The lens material has a light transmittance rate of nearly 92%, and the AR-coated layer increases the light transmittance to over 98%
• The lens has a waterproof coating, with a water droplet angle of 115 degrees, preventing water droplets from lingering on the lens and affecting shooting quality
• The snap-on design makes installation and removal simple and convenient
