ESS Eyewear Crossbow 2.4mm Replacement Lens
The replacement lens for the Crossbow eyeshield is built from extra-thick,
2.4mm high-impact polycarbonate, and features ESSOPTICS for distortion-free
clarity and 100% UVA/UVB protection. ESS ClearZone FlowCoat technology is
engineered to eliminate fog inside the lens and prevent scratches outside. The
Crossbow's DedBolt Lens Lock system allows for rapid lens interchange.
