摘要:
A visual function test apparatus comprises: a light projecting optical system (70) configured to irradiate stimulation light and background light to an examination area of a fundus (Er) of an eye (E) of an examinee reaction obtaining means (7c) configured to obtain a reaction of the examinee to the stimulation light and control means (80) configured to control at least an irradiation position of the stimulation light to be irradiated from the light projecting optical system to the examination area. The light projecting optical system (70) is configured to irradiate the background light at a luminance corresponding to dark adaptation and irradiate the stimulation light and the background light in a first wavelength band having a lower limit on a longer wavelength side than a sensitivity peak of blue cone cells and an upper limit on a shorter wavelength side than a sensitivity peak of green cone cells, the first wavelength band being a wavelength band including at least a sensitivity peak of rod cells.
