The Assos Donzi Fotodynamic cycling glasses feature photochromic lenses that adapt to ambient light levels to provide optimal visual comfort. Light transmission varies between 15% and 74%, depending on whether conditions are dark or bright. The lenses enhance contrast to highlight changes in texture, road imperfections and trail obstacles. Finally, these robust glasses won’t break in the event of an impact or a fall and are therefore suitable for road cycling, gravel riding and mountain biking.
