Abstract: An eyeglasses lens measurement device measures an eyeglasses lens of eyeglasses. The eyeglasses lens measurement device includes a light source that emits a measurement light flux toward the eyeglasses lens, a transmissive display that transmits the measurement light flux from the light source and displays an index pattern formed by arranging a plurality of indexes, a detector that detects the measurement light flux passing through the eyeglasses lens and the transmissive display, and a controller. The controller is configured to control a display of the index pattern, acquire an optical characteristic of the eyeglasses lens, based on a detection result of the detector, and acquire lens information different from the optical characteristic of the eyeglasses lens, based on a detection result of the detector.

Abstract: There is an provided eyeglass fitting parameter measurement device including: a display control unit that displays a front image of an examinee wearing an eyeglass frame and a lateral image of the examinee wearing the eyeglass frame on a display part; and a position information detection unit that detects position information for determining the positions of the examinee's eyes or the eyeglass frame based on one of the front image and the lateral image. The display control unit provides a correspondence indication corresponding to the position information detected by the position information detection unit in a display area for the other of the front image and the lateral image based on the position information.

Abstract: An ophthalmic device includes an anterior ocular segment photographing unit, a fixation target display unit, and a processor. The anterior ocular segment photographing unit captures an anterior ocular segment image of at least one of a left eye and a right eye of a subject. The fixation target display unit displays a fixation target with respect to the at least one of the left eye and the right eye of the subject. The processor measures an eye position of the at least one of the left eye and the right eye of the subject by processing the anterior ocular segment image captured by the anterior ocular segment photographing unit. The processor generates eye position state information, which indicates a state of the eye position of the subject, based on measurement results of the eye position at least two timings including a post-switch timing and a pre-switch timing.
