Duathlon sports glasseswith photochromic Bi-chromic lenses.
The BI-CHROMIC lenses bring a chromic color shift to photochromic technology. In this case, they shift from an orange color (Cat. 1), when deactivated, to a grey color (Cat. 3), at the time of maximum activation, yielding a luminal high-contrast effect for cloudy weather or overcast conditions, and an effective solar protection effect under very sunny conditions.
Possibility to mount prescription lenses with optional CLIP supplement.
Adjustable anti-slip nose pads.
