Paper Abstract

One of the main characteristics of the reaction of the pupil is the change that undergoes due of the luminance and color of the PC monitors. In this study, we evaluated the retinal illuminance in troland, i.e., total the luminous flux that affects the surface of the retina. For this investigation all the spectral of chromaticity was considered, wavelength from 390 to 660 nm, by means of system RGB and the functions of equalization of color XYZ, were exhibited in several PC monitors. The study was made projecting over on PC monitor, in three forms: full-field chromatic stimulation, the foveal target of 2 degree(s) on background white and on background blue of 15 degree(s) in both cases. In addition, the luminance in cd/m2 of each one of the monitors was measured. In order to quantify the changes of pupil area mm2, it was made by image processing of a video-oculography, which uses a video camera with sensors and illumination in the infrared range. Necessary condition when the observer is dark-adapted in scotopic or photopic conditions. The results obtained of retinal illuminance were made since wavelength 390 to 660 nm of ten subjects including at two persons with different colour vision deficiencies.
