A biker is subjected to completely different conditions within the shortest time. This demands higher versatility regarding his glasses, which the uvex sportstyle 810 v provides in perfection – due to the variomatic - technology, the glasses adapt continuously and automatically to changing light conditions in a split second. If the sun is blinding, your eyes are protected against the glare by the shaded lenses, contours become clearly visible. A little later, when the trail leads through the forest, the lenses clear up and guarantee full vision of shady root passages or blocked curves. Shaded or clear, the lenses protect your eyes against harmful UVA, UVB or UVC rays to 100%. With the anti-fog-coating supravision and ideally positioned ventilation openings at the edge of the lenses, the uvex sportstyle 810 v stays clear without steaming up.
