Show Description

Sporty-looking glasses for extremely bright conditions, like glaciers and the high altitude snow fields. Because they block 95 to 93% of visible light, they are way too dark for everyday activities and not suited to driving.

  • Flexible frame provides comfort and good hold.
  • Lenses provide just 5% visible light transmission, excellent for reducing glare from ice and snow.
  • Magnetic side-shields keep you protected from all angles and are removable when not required.
  • Rubber grips on the temples and nose-bridge keep them in position.
  • 6-base curve that ensures distortion-free viewing at all angles.
  • Grey Cameleon lens has 51 to 7% visible light transmission.
  • Grey Spectron 4 has 5% visible light transmission
