What are polarized lenses? 

Breakline's polarized Trivex lenses provide the benefit of filtering out reflected light and glare off cars, water, pavement, sand and snow. This lens technology works great for any activity where glare conditions exist. Only polarized lenses truly eliminate glare (reflected light).
Regular sunglasses simply darken visible light. Polarized lenses block glare with the use of highly effective polarized film encased between 2 layers of high impact Trivex material. Polarization is achieved by shutting out 100% of undesirable light and allowing 100% of desired light
through the lenses.
