Gehandicapt in het verkeer vanuit de visuele sfeer. Lezing gehouden tijdens de Eerste Verkeersmedische Dag `Gehandicapt in het verkeer'.

If a person is handicapped in his vision, he needs the advice of an oculist on his possible driving ability. Some people with specified handicaps are then advised not to drive at all, or to drive only in daylight or only with special provisions. Many people do not know that they have defective vision, especially in the dark.
