Seventy Nines

Calypso Dunes

Regular price $25.00

Lens Style

The lenses of polarized sunglasses reduce glare reflected at some angles off shiny non-metallic surfaces, such as water. They allow wearers to see into water when only surface glare would otherwise be seen, and eliminate glare from a road surface when driving into the sun.

  • Happiness guaranteed
  • Free returns on all standard US orders
