A first information processing device acquires an instruction signal for instructing an operation of a subjective optometry device, and transmits a drive signal for causing the subjective optometry device to operate as instructed by the acquired instruction signal to the subjective optometry device. When the first information processing device is remote-accessed by a second information processing device, the first information processing device can acquire the instruction signal input to the second information processing device by a user via a network. The first information processing device can further acquire a response input by an examinee who visually recognizes a presented target, and can further generate an instruction signal instructing the operation of the subjective optometry device based on the acquired response.

Non-transitory computer-readable storage medium and subjective optometry system

A subjective optometry system includes a plurality of subjective optometry devices and a database which stores at least any data of objective measurement data and previous glass data in association with each identifier. Each of the subjective optometry devices includes a calibration optical system, an information processor, and a reader which is connected to the information processor, reads an identifier prepared for each examinee, and outputs information about the read identifier to the information processor. The information processor acquires at least one of the objective measurement data and the previous glass data corresponding to the identifier from the database based on the identifier received from the reader, and sets an initial value of the calibration optical system used on an occasion of subjectively measuring optical characteristics of a subject eye based on at least one of the objective measurement data and the previous glass data.

Subjective optometry system

A subjective optometry apparatus includes: a subjective measurer which has a corrective optical system disposed on an optical path of a light projecting optical system configured to project a target light flux toward an examinee's eye and configured to change an optical characteristic of the target light flux and which is configured to subjectively measure an optical characteristic of the examinee's eye; an acquisitor configured to acquire position information on at least one of examinee's right and left eyes; a determiner configured to determine, based on the position information acquired by the acquisitor, whether or not subjective measurement can be implemented in a binocular open state of the examinee's right and left eyes, thereby acquiring determination information; and a determination information output unit configured to output the determination information acquired by the determiner.

Subjective optometry apparatus, subjective optometry method, and recording medium storing subjective optometry program

An optometry apparatus includes: an optical characteristic measurement device configured to measure an optical characteristic of right and left subject eyes in a both-eye opened state by projecting a visual target onto the subject eyes; an anterior ocular segment acquisition device configured to acquire anterior ocular segment images of the right and left subject eyes by the optical characteristic measurement device during the measurement of the optical characteristic of the subject eye in the both-eye opened state; and a controller configured to execute: an analysis instruction for performing analysis processing on the anterior ocular segment images acquired by the anterior ocular segment acquisition device to acquire both-eye opened state information; a determination instruction for determining whether the both-eye opened state information acquired by the analysis instruction is favorable or not, to acquire determination information; and an output instruction for outputting the determination information acquired by the determination instruction.

Optometry apparatus and optometry program

An optometric apparatus for correcting the refraction of an eye to be examined, which allows even a person who is inexperienced and unfamiliar with optometry to easily obtain appropriate prescription values, and conduct analysis of the visual function. The optometric apparatus has a rotary prism for imparting a prism power to the eye to be examined. An appropriate examination is conducted by using the rotary prism in accordance with a program stored in a memory to obtain the prism power of an expected state, and a result of examination is displayed.
