Abstract: Provided is an ophthalmic measurement device with which it is possible to obtain an area in which a measurement can be taken without moving an optical system. With reference to an optical path length of an illumination optical system with which light is focused on the eyeground when the refraction value is 0 D, the positions of two light sources are set to achieve a setting in which the optical path length becomes slightly shorter. By doing so, it is possible to cope with measurement of refractive properties in a large area without employing structures that allow a lens system of the illumination optical system and the light sources thereof to be moved. In addition, by selecting one of the two light sources so that a clearer Hartmann image can be obtained, it is possible to further increase the precision of the refractive properties to be measured.
