The invention relates to a method for testing visual field of a patient with use of a computer system (7) connected to an output-matrix of light points (6) having controlled brightness and to an input device (4) for measurement of patient's reaction. The method comprises the steps of: a) selecting by the computer system (7) the subset of light points from the set comprising all not yet examined light points of the matrix (6), b) defining by the computer system (7) the initial brightness for each point selected in step a), c) projecting by the computer system (7) subsequent light points of the matrix (6) from the subset of light points selected in step a) with different levels of the brightness starting from the initial brightness determined in step b), registering the reaction of the patient indicating whether the projected point is seen by him by the computer system (7) by means of the input device (4), and defining by the computer system (7) the level of the sensitivity of the retina of the patient in the given point, based on registered reactions of the patient, d) defining by the computer system (7) the map of the sensitivity of the retina of the patient. In order to enable shortening of the duration of the test and decreasing its arduousness for a patient as well as to enable to stop the examination before examining all points of the dot matrix without the loss of previously registered information on the quality of the patient's vision, before step d) at least one cycle of steps a)-c) is carried out, wherein in the first cycle of steps a)-c) the initial brightness of a given point projected is defined in step b) at least on the basis of the data concerning the patient, and in the second and each successive cycle of steps a)-c) the initial brightness of a given point projected is defined in step b) on the basis of the brightness determined for the other light points of the matrix (6).
