Abstract : The author discusses several physical problems involved in physiological optics, specifically the function of transmission of contrast by the eye, the visual capacity of the eye, the problem of color vision, and the visual capacity of the eye in twilight. The article is based on the German literature, particularly the works of O. Bryngdahl (Die Naturwissenschaften, 1964, 51, 177), and describes the current level of research in physiological optics. These problems are important in the manufacture of optical instruments. The author concentrates primarily on the problem of the function of the transmission of contrast in the visual system and methods of measurements. The methods of measuring the modulation function of transmission and the threshold modulations on the retina of the eye are described, as is the method used by A. Arnulf (Abbilden und Sehen, Munchen, 1962, VI. Internationaler Kongress fur Optik, 11-15) and those used by Bryngdahl. The contrast test is explained by means of diagrams. The author points out that the article does not cover all the problems involved. The original article has four figures. (Author)
