摘要： There is provided a test method for visual characteristics which is less load to a subject and enables testing of visual characteristics of the subject, a test image set for testing visual characteristics, a determining method for determining characteristics of correction filter based on a test result of visual characteristics, and a correction filter made based on it. The test image set includes multiple test images. Each of the multiple test images has a background area and a test area located in the background area. The multiple test images are provided with figures having colors different from a color of the background area in at least one of R, G, or B components in a RGB color space, and the multiple test images are different from each other in colors of at least one of the background area or the test area.

摘要： A method for testing visual characteristics includes a providing step of providing a subject with a test image and a changing step of changing an optical element to be placed between the subject and the test image. The test image includes a first image area containing a color to which rod cells are sensitive, and the first image area is placed in such a manner that light coming from the first image area forms an image on a region outside a central fovea of a retina when the subject is looking at a center of the test image. The optical element set includes a plurality of first optical elements configured to transmit light of a first wavelength band to which the rod cells are sensitive within a visible light band. An optical element that the subject does not feel dazzled by the test image is specified.
