Green Hat Sunglasses Replacement Lenses

The Lenses are impact resistant and scratch resistant 1mm Polycarbonate grey lens. The Lenses are also ANTI-FOG coated.

UV400 Rated lens： This optically correct lenses provide UV400 protection from harmful rays.

Polarized lens：Polarized lenses are used in these sunglasses to reduce glare from reflective surfaces such as the surface of water or the hood of a car. They accomplish this feat through a process called polarization, much like a venetian blind controls sunlight through a window.

Sunlight itself is not polarized - light from the sun will either be absorbed or reflected horizontally, diagonally or vertically. The problem this causes for kiteboarders and drivers lies in the horizontal reflectivity. Sunlight bouncing off a horizontal surface will strike the viewer's eyes at a similar angle. This means the glare from the surface of the water or the road or the car hood will be strong. Polarized lenses have a laminated surface containing vertical stripes. These stripes only allow vertically-polarized light to enter the wearer's eyes. Glare is eliminated because the horizontally-polarized light waves cannot bypass the polarized filter.

The Grey color lenses are best suited for sunny conditions. They are also good for driving or general use when true color perception is important.
