Put simply, polarized lenses eliminate glare, which is defined as light reflected on any surface. These special lenses make it easy to see in sunny conditions and protect our eyes from harmful UV rays. Polarized lenses can be combined with other features to enhance vision, such as bifocal sunglasses and progressive lenses, and coatings like anti-reflective and anti-scratch.
