Polarized sunglasses feature a special chemical film coating that helps reduce glare. When light hits a flat surface like water or snow, it reflects horizontally, creating blinding light. Polarized lenses filter out these waves, providing clearer vision and reduced eye strain.

They serve different purposes: UV protection shields your eyes from radiation, while polarized lenses eliminate glare. For optimal eye health and clarity, Zenottic polarized sunglasses come equipped with UV400 protection.

Typically, high-quality polarized sunglasses last 2 to 3 years. Environmental factors like heavy UV exposure and scratches can degrade the protective coatings. We recommend storing them in a hard case when not in use.

Not recommended. UV protection levels can decline over a decade, and your vision prescription may change. Updating every few years ensures you have the latest lens technology and maximum eye protection.
