Methods, apparatus, and systems for performing an ophthalmic diagnostic test are disclosed. In one aspect, a head-wearable device for administering an ophthalmic test to a subject can comprise a head-wearable frame for mounting the device onto the subject's head, and a light seal configured for coupling to the frame so as to isolate at least one eye of the subject from ambient light when the device is worn by the subject.

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 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.

A waveguide apparatus includes a planar waveguide and at least one optical diffraction element (DOE) that provides a plurality of optical paths between an exterior and interior of the planar waveguide. A phase profile of the DOE may combine a linear diffraction grating with a circular lens, to shape a wave front and produce beams with desired focus. Waveguide apparati may be assembled to create multiple focal planes. The DOE may have a low diffraction efficiency, and planar waveguides may be transparent when viewed normally, allowing passage of light from an ambient environment (e.g., real world) useful in AR systems. Light may be returned for temporally sequentially passes through the planar waveguide. The DOE(s) may be fixed or may have dynamically adjustable characteristics. An optical coupler system may couple images to the waveguide apparatus from a projector, for instance a biaxially scanning cantilevered optical fiber tip.

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.
