When researchers at NASA's Jet Propulsion Lab were developing eye protection for welders, they discovered that the eyes of hawks contained an orange-tinted oil that both protected the birds' eyes from UV light and enhanced their visual clarity. This scientific breakthrough is the basis for the Avian Orange lens coating. Its superior blue light filtering properties make targets stand out, for outstanding vision enhancement. For shooters, it also boosts depth and distance vision in distracting outdoor conditions. Adjustable, nose pads, soft temple tips, and flexible frame allow you to adjust for a perfect fit. Semi-rimless, wrap style. In orange/black.
