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.
