摘要： A subjective optometry apparatus has a projection optical system including a visual target presenting portion and an optical member to project a target light flux toward a subject eye, and causing the target light flux to be incident on the optical member with a deviation of the incident target light flux from an optical axis of the optical member, a housing accommodating the projection optical system, a presentation window for emitting the target light flux from the inside of the housing to the outside thereof, an eye refractive power measurement unit provided outside the housing, and holding means integrally connecting the housing to the eye refractive power measurement unit to hold the eye refractive power measuring unit. When using the eye refractive power measuring unit, a distance from the presentation window to the eye refractive power measurement unit in an optical path is equal to or less than 180 mm.

摘要： 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.

摘要： 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.

摘要： There is provided a subjective eye refracting power measurement apparatus which measures a refracting power of a subject eye. The apparatus includes a projection optical system which projects a visual target light flux toward the subject eye to form a visual target on a fundus of the subject eye; a correction optical system which changes a refracting power thereof; a relay optical system which relays a light flux passing through the correction optical system and to form an image of the correction optical system in front of the subject eye; a deviation detector which detects a positional deviation of the image of the correction optical system with respect to the subject eye; and a correction unit which optically corrects a formation position of the image based on a detection result by the deviation detector such that the image is formed in front of the subject eye.
