A method and apparatus are disclosed for testing the physical/mental fitness of a subject by observing his/her eye responses to stimuli in the form of images in motion displayed on a screen. The method comprises the steps of monitoring the eye behavior of the subject in response to movement of the images, analyzing the resulted responses, comparing the results to a reference eye pattern, and determining the level of fitness according to the comparison results. The apparatus is intended to be used for self-testing e.g. by bus drivers or equipment operators and may be coupled so as to disable operation of the vehicle or equipment by unfit subjects.
