Quantitative determinations of the absorption of ultraviolet radiations by different structures of the eye are of importance, since various pathologic conditions, such as cataract,1retinal damage2and functional visual disturbances,3have been variously ascribed to these radiations. The measurements of absorption of ultraviolet radiations by ocular media made heretofore have been limited to photographing narrow bands of radiations transmitted through the eye. As pointed out by the author of one of these papers,4the data obtained by this means are qualitative, since it is difficult to estimate the proportion of the radiations which is transmitted through the ocular structures. In the present study quantitative information was obtained by measuring photoelectrically the fraction of radiation which was transmitted. MATERIALS AND METHODS All the measurements were made on the eyes of young adult albino rabbits, weighing approximately 2 Kg. Technics used in determining the absorption of ultraviolet radiations
