A method of manufacturing a substrate includes applying solder resist ink containing a mixing resin of epoxy-based resin and acrylic-based resin on at least one surface of a substrate body to form a solder resist layer, and irradiating a predetermined portion of the solder resist layer with ultraviolet rays and controlling an amount of irradiation of the ultraviolet rays irradiated to the predetermined of the solder resist layer to form the predetermined portion in transmissivity that transmits light.

[Problem] To be able to accurately measure color vision and color-viewing field for different colors. [Solution] The color-viewing function measuring means () pertaining to the present invention displays a plurality of chromatically colored targets (A, . . . ) (for example, Landolt rings) in an achromatic background (B), the brightness of the targets (A, . . . ) 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 (), vision and viewing field can be accurately measured for different colors.

A color perception test has a color matching processor that executes a color matching processing on a color monitor, and an image display controller that displays two or more images for color perception test in order on the color monitor on which the color matching processing was done. When displaying each image for color perception test, a color perception test is done in a state that one of its hue, brightness, saturation and display time is changed and the other elements are fixed. Since the color perception tester has the color matching processor, colors of the image are not changed with passage of time different from color printed one, and correct test can be done thereby. If the test is periodically done on some examinee, a degree of decreasing color perception function by aging can be exactly known.
