Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

A visual field observation training lens is disclosed, along with corresponding training eyewear. An associated method for training visual observation toward a designated field of view is provided.

A presbyopia diagnosis apparatus includes: a measurement bar that is elongated along an axis in one direction, has a front end arranged to face the eyes of a subject for presbyopia measurement, and a rear end connected to a support, wherein a scale for measuring a distance is marked on the measurement bar; and a sliding unit that is movably installed on the measurement bar and has an installation groove formed therein, the installation groove for mounting a card for measuring presbyopia.

An apparatus includes a training area in the form of an enclosed space in which light levels can be controlled, at least one physical element related to a task for which an individual is to be trained, and a lighting arrangement. The lighting arrangement generates a background luminance level in the training area sufficient to cause the vision system of the individual to function in the mesopic or low photopic range of vision, and the physical elements are themselves illuminated by an illumination means. The luminance level of the physical elements is greater than the background luminance level.

A multi-stimulation neurorehabilitation assistant system, comprising a support unit, an audio stimulation unit, an acupoint stimulation unit, an electronic stimulation unit, a training unit, a display and optical frequency-flashed stimulation unit, and a control unit. The support unit includes a rotatable top-side portion over the top of the user's head. The audio stimulation unit includes two speakers. The acupoint stimulation unit includes several acupoint agents. The electronic stimulation unit includes several electronic stimulation agents. The training unit can sense user's own movements to output measurement signals. The display and optical frequency-flashed stimulation unit can be switched between a display mode and an optical frequency-flashed stimulation mode. The control unit electrically connected with the speakers, the acupoint agents, the electrical stimulation agents, the training unit and the display and optical frequency-flashed stimulation unit, so that users can obtain multiple stimulations at the same time during rehabilitation.

The visual function test device of an embodiment comprises a test subject display device and an operator display device. A target display portion displays a target image to be viewed by the test subject onto the test subject display device. A visual axis estimation portion estimates a visual axis of the test subject when the target image is viewed. A position display portion displays a display position of the test target image and a viewpoint position that corresponds to the estimated visual axis, onto the operator display device, and thus a tester can objectively recognize a gazing state of the test subject and surely perform the test, which enhances the reliability of the test.

A vision restoration device includes a body part and an eye piece part. The body part has a tubular holding part and a bottom part closing one end of the holding part. The eye piece part has a shape that fits the shape of eyelids covering an eyeball of a user, and has a projecting part that projects outward of the body part. In using the vision restoration device, the eye piece part is brought into contact with the eyelids to be massaged with the projecting part oriented toward a predetermined direction, and the vision restoration device is rotated, slid, or reciprocated.

Methods and systems for dynamically prescribing therapeutic games for treatment of ocular disorder are disclosed. The methods and systems include: performing an eye position calibration technique in a virtual reality environment to calibrate the virtual reality environment to a user; performing an eye movement measurement to produce a diagnosis result; selecting a virtual reality therapeutic game based on the diagnosis result; performing the virtual reality therapeutic game to receive a game user input in the virtual reality therapeutic game; and dynamically adjusting difficulty of the virtual reality therapeutic game based on the game user input. Other aspects, embodiments, and features are also claimed and described.
