The Spectral Sensitivities of the Middle-Wavelength and Long-Wavelength Sensitive Cones

Abstract

Previously we reported the development and validation of a technique of estimating the spectral sensitivities of the middle-wavelength sensitive (MWS) and long-wavelength sensitive (LWS) cones that relies on the use of transient adaptation conditions. The spectral sensitivity for detecting 17-Hz flicker is measured during the first 500 ms following a change of background color from deep-red to blue for LWS cone isolation or vice versa for MWS cone isolation. In this paper, we report the final analysis of the MWS and LWS cone spectral sensitivities obtained in two protanopes, four deuteranopes and eleven normals.
