Curved Watch Crystal Sapphire Glass

Why do sapphire glass choose AR coating treatment?

An anti-reflective coating (or AR coating) is an optical coating that consists of different transparent layers that are applied to glass crystals using a physical vapor deposition (PVD) process.Both mineral watch glass and sapphire watch glass will have AR coating, but this coated sapphire glass is widely used. Glass has various reflective properties, most of which are prone to glare. Different reflection qualities have a direct impact on the performance of the lens.

The reason why most people choose anti-reflective coatings is to improve the performance of the watch glass to prevent it from reflecting light, adding this AR coating to the watch glass will not destroy the clarity.Watch glass varies in AR performance, durability, and legibility.This is why adding AR coating to all sapphire crystals has become a necessity rather than a luxury, as it improves the legibility of the watch dial.The coatings in sapphire glass with AR coating have different colors, and the color tone of the coating is also created by the manufacturer. The coating has clear color, blue, red, etc. Clear color is more chosen by many people.
