Exploring A Short-Wavelength Sensitive Cone Mechanism To Brightness And Discomfort Glare, David Glabe

David K Glabe

Yellow lenses have long been reported to alter visual perception, including subjective impressions of brightness and discomfort glare. To date, no consensus has been reached regarding the physiological mechanism behind this altered perception, although recent research suggests a possible short-wavelength sensitive cone (S-cone) mechanism. An experiment was conducted to test the hypothesis that S-cones are responsible for the perceived increase in brightness and decrease in discomfort glare perception when viewing through yellow lenses. Thirty participants were asked to use neutral density filters to match perception of brightness and discomfort glare through colored filters and with no filters in low and …
