Polarized lenses in sunglasses are designed to reduce glare from surfaces such as water, snow, and roads. They contain a special filter that blocks intense reflected light, allowing only vertical light to pass through.

Polarized lenses are also effective in reducing the harmful effects of UV rays, providing added protection for the eyes. **
