  • 95% High-Energy Visible (HEV) light reduction promotes clarity

  • Durable See Grass frames are manufactured from recycled plastic and agricultural grasses using renewable energy
  • ProFlex rubber on the nose and temple tips provides a soft and comfortable hold while keeping sunglasses in place no matter what the day brings
