We are extremely proud of the quality of the lens material we offer. Providing a perfectly crisp and real color perception through harmonious alignment of our lens materials and the finest polarized filters.Our Polarized lenses are all about eliminating glare which is caused by direct light from a single light source such as sunlight, car headlights or reflected from snow, water, cement, ice or sand. Polarized lenses are designed to eliminate or reduce the intensity of glare by passing light through a special filter imbedded with tiny crystals.The base curve of a frame is based on the measured sphere from the back of the lens. Peppers offers styles with 6,8 and 9 base end curvature. The 6 base models follow the natural curvature of your eye and 8 & 9 base models provide maximum coverage around your face.
