Graduated Polarized coating is a filter that includes a dark, protective film that permanently colors the lens.
This special coating is applied to the surface of the lens in order to reduce glare.
The sole purpose of this polarization is to give lenses this anti-reflection function.
By ensuring greater contrast, you see more clearly with reduced glare, so you can have more confidence in what you see around you.
Polarized lenses are great for every sport — especially sailing, cycling, and running — and other outdoor activities that involve constant exposure to sunlight.
They are also ideal for driving because of their ability to reduce glare.
