GIST Mask Photochromic Glasses

The photochromic system allows the lenses to undergo a reversible chemical reaction when exposed to UV radiation or sunlight, gradually darkening them. They return to their original clear state when exposure to light or UV rays ends. Glasses with a top-class weight of 30g, thanks to the extended, single-piece, raw-cut polycarbonate shield with 100% protection against UVA, UVB and UV rays. The polycarbonate lenses of the Mask glasses provide 100% protection against UVA, UVB and UV rays, with anti-fog vents that ensure consistent optical quality. They minimise reflections, sunlight, moisture, sweat and adverse weather effects. The tapered, flexible temple tips and adjustable nose pad ensure a perfect hold even during sudden movements, so you can cycle in complete safety.
