Yes, there are two groups:
1st group: Category A (motorcycle), A1, B (car), B1, F, Gund M
2nd group: Category C (truck), C1, D, D1, passenger transport, traffic expert
When driving a passenger car, a driver must be able to fix a distant point on the road. Traffic signs, zebra crossings and town signs must be able to be recognized at greater distances in order to maintain traffic flow. This is only possible with appropriate visual acuity, which can be achieved either with or without glasses.
Children playing in a cross street or pedestrians walking on the sidewalk must be visible in the peripheral field of vision of the driver in order to ensure timely braking readiness. Failures in the field of vision can result in pedestrians being detected too late, for example.
Horizontal >120° (extension left/right at least 50°)
Vertical > 40° (up/down extension at least 20°)
The driver must be able to quickly change the direction of vision from the fixing point in the distance to passers-by on the side of the road in order to be able to determine whether they want to cross the road or not. The eyes must therefore be able to move in different directions in a very short time without seeing twice.
Visual acuity should enable clear vision at a distance as well as at medium distances (e.g. using progressive glasses). This requirement is not explicitly required by law.
Drivers must have sufficient visual acuity not only in daylight but also at dusk to be able to safely participate in road traffic. Small visual defects are often only annoying at dusk, as is slight clouding of the natural lenses (beginning cataract).
Increased sensitivity to glare can affect the vehicle driver and thus reduce safety as a road user. Glare is a phenomenon that usually results from opacities in the tear film, in the cornea or in the natural lens (beginning Grauer Star) is attributable.
