A vehicle 1 with a transparent roof area 4 has at least one roof window 6 tailored to fit into the roof structure 5. An adjustable darkening against exposure to incident light is provided toward the passenger compartment 8. The roof area 4 has a first optically structured, immovably fixed surface 10 and a second optically structured, movable surface 11. The first and second surfaces 10, 11 are arranged one over the other. The second surface 11 here abuts the first surface 10 so that it can slide over it. While the first surface 10 takes up the entire roof window, the second surface 11 is arranged at least in partial areas of the roof window 6. The second surface 11 is arranged so that it can move relative to the first surface 10 in such a way that the optical structures lying one over the other alter the incident light as a function of position. The surfaces may have striped or spotted patterns, or polarization patterns.
