title: An ergo-ophthalmological battery of tests to classify truck drivers.
abstract: 16 healthy and ophthalmologically normal truck drivers are tested with a battery of tests according to the routine described in the following paper. This includes isopter perimetry, colour discrimination, recovery of sensitivity during dark adaptation and refraction at both far and near points, in order to record night myopia as well as night presbyopia. The ranges of individual variability are reported. As far as refraction is concerned, it seems of interest to stress the individual differences in a sort of "transient anisometropia" under incoming twilight.
