All of our sunglasses are made with TAC 1.1mm polarized lenses. We believe that everyone should be able to have the fashion frames they want with the protection they need. Polarized lenses offer several advantages compared to basic lenses. A basic lens reduces the transmittance of light through the lens, protects the eye from UV radiation, and reduces glare somewhat. Polarized lenses do all of these things and more! They actually eliminate glare, which is especially nice while driving or riding in a boat. Polarized lenses filter horizontally polarized light that reflects off flat surfaces, such as roads and smooth water. They allow the vertical component of light to pass through the lenses, which produces a clearer view. Because of this method of filtering light, they improve the contrast of your environment and offer a true perception of colors. Wearing polarized lenses enhances your vision because you are seeing a clearer, more vivid, glare-free world!
