[Eyes for cars].

Driving is the preferred mode for transportation in many parts of the world and may also be the only available alternative. The driver's ability may however be disturbed by many medical conditions. The visual requirements for driving in Sweden is based on the third European driving license directive but also adds more specified requirements of visual field, related to the methods used in health care. On the other hand Sweden has no regular testing of the visual acuity among elderly. Physicians in Sweden are obliged to report unsuitable drivers to the state. Dispensations from the visual field requirements are possible after a positive statement from a medical authority and a successful test in a driving simulator. This test is expensive for the patient (2 000 euro) and only available at one site. Future research of data from the simulations could hopefully create more evidence-based visual requirements to distinguish safe from unsafe drivers.
