A visual guide for assisting a user with the positioning of an object relative to the user’s eye is provided. The visual guide comprises: a first positioning indicator provided on an axis; and a second positioning indicator, visually distinct from the first. The first and second positioning indicators are offset along the axis. Furthermore, visual contact of the first and second positioning indicators occurs when the object is located within a predetermined locus of the user’s eye.

A non-transitory, computer readable, storage medium stores a self-optometry control program that is executed by a first information processing device and includes a self-optometry program. The self-optometry program causes the first information processing device to perform executing a calling operation based on a calling instruction and setting an examination timing for an assistance operation such that the assistance operation starts from an examination item that was performed at a timing the calling instruction was inputted.

Systems and methods are disclosed for evaluating human eye tracking. One method includes receiving data representing the location of and/or information tracked by an individual's eye or eyes before, during, or after the individual performs a task; identifying a temporal phase or a biomechanical phase of the task performed by the individual; identifying a visual cue in the identified temporal phase or biomechanical phase; and scoring the tracking of the individual's eye or eyes by comparing the data to the visual cue.

A method of, and apparatus for, aligning an ophthalmic instrument relative to an eye is disclosed, and can include aligning an esthesiometer with a patient's eye. Other aspects of the method and apparatus of the present invention are further described herein.

A handheld evaluation device includes an image recorder configured to capture at least one of still images or video images, a function switch configured to operate the image recorder, a plurality of timers, each of which is associated with one or more portions of a substance evaluation protocol, and processing circuitry coupled to the image recorder, the function switch, and a plurality of actuators operatively associated with the plurality of timers. The processing circuitry is configured to initiate a first timer of the plurality of timers in response to detecting the activation of a first actuator of the plurality of actuators, activate the image recorder in response to detecting operation of the function switch, provide feedback associated with the first timer, determine completion of the first timer, and store in memory the at least one of still images or video images captured by the image recorder.

Ophthalmic imaging systems and related methods provide pseudo feedback to aid a user in aligning the user's eye with an optical axis of the imaging system. An ophthalmic imaging system includes an ophthalmic imaging device having an optical axis, a display device, an eye camera, and a control unit. The display device displays a fixation target viewable by the user. The eye camera images the eye to generate eye image data. The control unit processes the eye image data to determine a position of the eye relative to the optical axis, processes the position of the eye relative to the optical axis to generate a pseudo position of the eye relative to the optical axis, and causes the display device to display an indication that provides feedback to the user that the eye is located at the pseudo position of the eye relative to the optical axis.

A method, computer program product, and system includes a processor(s) utilizing the image capture device to track eye movements of a user interacting with a display communicatively coupled to the one or more processors, the image capture device continuously collecting image data. The processor(s) determines, based on analyzing the collected image data, a probability of whether a user may be experiencing a vision-related issue. Based on the probability being within a given pre-determined range, the processor(s) identifies the vision-related issue experienced by the user. The processor(s) generates, based on the vision-related issue, a two dimensional visual exercise to address the vision-related issue for performance by the user. The processor(s) deploys a graphical user interface to the display, where the graphical user interface comprises the visual exercise. The processor(s) provides the visual exercise to the user via the graphical user interface.

A non-transitory, computer readable, storage medium stores an optometry control program including a self-optometry application program. The self-optometry application program, when executed by a first information processing device, causes the first information processing device to perform executing an assistance operation to assist in a progress of a self-optometry for an examinee when a problem occurs during the progress of the self-optometry.

Imaging various regions of the eye is important for both clinical diagnostic and treatment purposes as well as for scientific research. Diagnosis of a number of clinical conditions relies on imaging of the various tissues of the eye. The subject technology describes a method and apparatus for imaging of the back and/or front of the eye using multiple illumination modalities, which permits the collection of one or more of reflectance, spectroscopic, fluorescence, and laser speckle contrast images.

The disclosure relates to a method and a respective computer program with a program code to execute the method. In particular, disclosed is a method for training a preferred retinal locus of fixation (efficient PRL) for a person having an eye with a field of vision comprising an area of partially diminished or entirely degenerated visual acuity. The method includes: a) determining an inefficient retinal region outside the area in the field of vision of the eye of the person and a more efficient retinal region for the specific vision task outside the area in the field of vision of the eye of the person and b) inducing a preferred retinal locus of fixation (efficient PRL) for a vision task outside the inefficient retinal region but in the more efficient retinal region. In addition, the disclosure relates to a device for performing the method.
