Anti-reflective Superhydrophobic (ARS) coating is applied to the surface of your lenses to reduce the amount of reflected light, which can cause glare, ghost images, and other visual artifacts. While the Superhydrophobic end of the coating helps repel water and other liquid droplets from adhering to the surface, causing them to bead up and roll off. It will help prevent your glasses from fogging up.

Anti-reflective coatings eliminate the distracting glare that can be produced by light when it reflects through your lenses. Anyone subjected to direct or indirect reflections – especially those who spend a lot of time around computers and electronic monitors of any type, suffer from eye strain, or who drive at night – will likely enjoy the benefits of glare reduction. Due to the high reflective properties of high index lenses, an anti-reflective coating is recommended, and is practically mandatory for high index lenses made of glass. (Note: AR coating is not good for outside glasses, dusty dirty environments and or constant cleaning.) The lenses must be wet before they are cleaned.
