Anti-fog Coating
Newly developed lens coating that prevents the rear lens surface from fogging up.
When does fog appear?
When humidity coming off the body gets trapped behind the lenses, and the lens temperature is lower than that of the trapped humid air, then the rear surface of the lenses fog up.
Anyone who wears glasses is likely to have experienced the discomfort of blocked vision when the rear surface of their lenses fog up, virtually blinding them. This can be uncomfortable, disturbing, or even dangerous.
It can happen when stepping out in the cold, or when entering an air-conditioned environment, and it's most likely to happen during strenuous activity when the body is giving off more heat, and humidity gets trapped behind the lens.

- Sports, both indoors and outdoors
