COLOR-VIEWING FUNCTION MEASURING MEANS AND COLOR-VIEWING FUNCTION MEASUREMENT SYSTEM

摘要

[Problem] To be able to accurately measure color vision and color-viewing field for different colors. [Solution] The color-viewing function measuring means (1) pertaining to the present invention displays a plurality of chromatically colored targets (A 11 , ...) (for example, Landolt rings) in an achromatic background (B), the brightness of the targets (A 11 , ...) being set so as to be substantially equal to the brightness of the background (B) . When vision or the viewing field is measured with this color-viewing function measuring means (1), vision and viewing field can be accurately measured for different colors.
