If temperature changes from one environment to another cause fogging on your lenses, then with FOG-FY, this will change. FOG-FY is a multi-layer anti-reflective coating (9 layers on each surface of the lens) applicable to all organic lenses, featuring anti-static, oleophobic, and superhydrophobic properties. Thanks to a special finishing process, the FOG-FY treatment prevents lens fogging caused by temperature fluctuations, for those wearing masks and in kitchen environments, resisting temperatures up to 60°C.
