Green Hat Sunglasses Replacement Lenses

The sunglasses feature impact-resistant and scratch-resistant 1mm polycarbonate grey lenses. The lenses are also coated with an anti-fog treatment.

UV400 Rated Lenses

These optically correct lenses provide UV400 protection, shielding the eyes from harmful ultraviolet rays.

Polarized Lenses

The sunglasses are equipped with polarized lenses, which are designed to reduce glare from reflective surfaces, such as the surface of water or the hood of a car. This is achieved through a process called polarization, similar to how a venetian blind controls sunlight through a window.

Sunlight itself is not polarized - it can be absorbed or reflected horizontally, diagonally, or vertically. The problem for activities like kiteboarding and driving lies in the horizontal reflectivity. Sunlight bouncing off a horizontal surface will strike the viewer's eyes at a similar angle, causing strong glare.

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.
