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.

The present disclosure provides an improved method for photobleaching an eye of a subject. The disclosed method may be used in a number of psychophysical test methods, including, but not limited to, measurement of dark adaptation. The improved method for photobleaching involves at least one of the following improvements: (i) the use of a bleaching light emitting a particular wavelength of light or a tailored spectrum of wavelengths; (ii) restricting or otherwise spatially tailoring the region of the retina that is subject to photobleaching; and (iii) utilizing a bleaching light having an intensity that is at or below the intensity of ambient daylight. The present disclosure additionally provides a combination of a photobleaching light and an apparatus to administer a psychophysical test suitable for use in practicing the disclosed methods.

A virtual reality display system including at least one optical alignment subsystem optically aligned with at least one eye of a subject and at least one virtual reality display device optically aligned with the at least one optical alignment subsystem for displaying to the subject at least one virtual reality object undergoing virtual motion, wherein the virtual motion of the at least one virtual reality object as viewable by the subject is operative for inducing and relaxing accommodation by the at least one eye of the subject.

An evaluation device includes a display screen; a gaze point detection unit that detects a position of a gaze point of an examinee; an area setting unit that sets a specific area for a first indicator on the display screen; a determination unit that determines whether the gaze point is present in the specific area based on the position thereof; a display controller that displays a second indicator at a different position from the first indicator when determining that the gaze point is present in the specific area; a arithmetic unit that determines whether the examinee has recognized the second indicator; and an evaluation unit that evaluates a visual function of the examinee based on a determination result from the arithmetic unit. The display controller doesn't display the second indicator when determining that the gaze point isn't present in the specific area after the second indicator has been displayed.

An ophthalmologic examination system that examines a subject's eye with an ophthalmologic apparatus includes an information acquisition portion that acquires a patient's ID determined for each patient and an examination order determined for each patient, an information storage portion that stores the patient's ID and the examination order which are obtained by the information acquisition portion and are linked, an ID reception portion that receives input of the patient's ID, an order read-out portion that reads out the examination order linked to the patient's ID received by the ID reception portion from the information storage portion, and an examination control portion that sets the ophthalmologic apparatus to at least an examination ready state based on the examination order read out by the order read-out portion.
