Polycabonate Frame with TAC 0.65mm HD Polarized Lens. The process of polarization uses a filter to absorb glare producing light waves reflected off horizontal surfaces. Polarization is similar to a chemical venetian blind, rearranging light and allowing you to see “through” harsh glare and reflection. 100% polarized lenses are the only truly effective way of eliminating glare. Water, fog, rain, snow and early morning dew, have reflective properties, which enhance reflected glare. This particular style can be worn over your perscription eyewear.
