The photochromic lenses react fast to changing light conditions and quickly transition from clear to dark. This poses a particular challenge for road bike riders who need to be able to see every detail of the road ahead. The uvex sportstyle 804 V has a modern shield look and uvex variomatic® technology which smoothly changes from clear to dark in just 25 seconds. As such, it copes perfectly with variable conditions. In addition, the large lenses protect the eyes from draughts, while the frameless design delivers unrestricted views when riding. The ultra-light sports glasses’ lenses are also extended at the top to protect from UVA, UVB and UVC even in low road bike riding position.
