Hardened 8 Layer Waterproof Multi-coating Newly developed industry leading 8-layer multi-coating yields an average light transmission rate of 99.35% between 400 & 700nm (visible spectrum). These coatings greatly reduce reflections off the surface of the glass allowing you to capture more light in your photos. As with all Hoya multi-coatings, HD HMC is applied in a furnace at high heat, bonding the coating to the surface of the glass. This process is called "hard coating" & it is far more durable than other coating techniques. The chemistry of the top layer is formulated not just to be more durable but to be resistant to oil stains. This means that finger prints & other oils are much easier to remove.
