title: Studying the stability of clear vision using microcomputer "Pravets-82".
abstract: The method of Ferree and Rand assesses the efficiency of the eye and is very sensitive to fatigue in the visual system. A modification of the method is developed using microcomputer "Pravetz-82". The proposed algorithm is realised in Extended Basic. The features of the modified method include: display of the stimulus on the monitor of the microcomputer, option for interactive change of the parameters of the stimulus from test to test, storage of the data on a diskette, measuring of the time intervals by a programme clock, statistical evaluation of the results with graphic display. The modification makes the method more versatile, precise, and easy to perform.
