UV radiation is high-energy electromagnetic radiation, with short wavelengths, invisible to the human eye. Even though we cannot see it, it reaches our skin and eyes and our tissues absorb it. The ERP coating is applied on lenses to provide maximum UV protection for our eyes and the surrounding area.
The ERP protective coating blocks UV range at 400 nm so that transparent lenses provide UV protection like quality sunglasses.
The protective ERP coating can be combined with other Grossoptic coatings to enable complete UV protection.
