• Flex Hinges: Flexible and comfortable arms with spring hinges that adapt to all face shapes and sizes.
• Category 3 Solar Lenses: Ultraviolet rays damage eye cells. Over time, renewal will become less effective. SUN glasses provide customized protection with category 3 UV lenses, which protect against glare and filter 100% of ultraviolet (UV) rays.
• Bio-based Material: The frame of the glasses is made from 45% bio-based polyamide derived from castor oil.

Polarized lenses include a special filter that blocks intense reflected light, which actually reduces glare and adds greater protection to your eyes.
