Atomic Savor L Photo goggles respond to changing light conditions by adjusting the level of tint. The cylindrical double lens lightens as conditions get darker, and darkens in sunshine to protect your eyes from glare. The lens has a multilayer treatment that reduces eye fatigue. The Savor L Photo has large frame suited to broader faces or those who like some extra room, and have additional comfort thanks to the Live Fit frame that molds to the contours of your face. They’re OTG - they fit comfortably over prescription glasses if needed. - Lens technology -Photochromatic - Weight – 140g
