The Huub Aphotic Photochromatic Goggles have special patented photochromic dyes that cause the lens to activate and darken when exposed to ultraviolet rays from the sun. When the UV light fades, the lenses fade back and as the light conditions change, the level of tint adjusts. They are designed to fit the face perfectly with a lightweight feel.
Features:

• From clear to dark for ultimate performance
• Designed to fit the face perfectly
• Anti fog and scratch resistant lens
• Self-regulating lens that delivers comfort and vision needed to maximise your swim
