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.

Disclosed are training method, program and computing device to ameliorate visual field defect. The method includes presenting, by a computer, a virtual first object on a screen, wherein the first object is presented in an approaching manner toward the subject from a first position to a second position, when a position of the first object reaches the second position, the dividing, by the computer, of the first object into objects and presenting the divided objects on the screen or removing, by the computer, the first object from the screen, when the first object is divided or removed, presenting, by the computer, a virtual second object and a virtual third object on the screen, and receiving, by the computer, an identification input about the second object and the third object from a response input device of the subject.

Examples of assessing vergence capability of an individual are described. In an example, a first random dot stereogram is generated. The first random dot stereogram includes a first random arrangement of dots and a first sub-portion positioned against the first random dot stereogram. Thereafter, an input from an individual, identifying the position of the first sub-portion against the first random dot stereogram may be received. In response to receiving the input, a second random dot stereogram comprising a second sub-portion positioned against the second random dot stereogram, is generated. The second random dot stereogram comprises a second random arrangement which is different from the first random arrangement of dots in the preceding first random dot stereogram. In response to the second random dot stereogram, another input to identify position of the second sub-portion against the second random dot stereogram is received.

A portable system and method for training an alternate retinal location of a viewer's eye with impaired retina and an assistance system for improving vision of such viewer's eye are disclosed. The portable system for training comprises an eye tracking module to provide eye information of the viewer's eye and a virtual image display module to display a virtual image centered at the alternate retinal location on the viewer's impaired retina other than centered at a fovea. The virtual image display module further comprises a first light signal generator to generate multiple first light signals and a first combiner to redirect the multiple first light signals towards the alternate retinal location, when a pupil of the viewer's eye is located approximately at the center of the viewer's eye.

Disclosed are methods and devices useful in the field of image processing and display Disclosed are also methods and devices useful in the field of ophthalmology and, in some particular embodiments, useful for the non-invasive treatment and/or prevention of refractive errors.

It is an object of the present invention to provide a vision training device having an excellent vision training efficiency as vision training is performed in consideration of a status of personal vision. In order to achieve the above object, a vision training device according to the present invention includes a refractive index-adjustable lens disposed in a field of view direction of an eye of a user and having a refractive index which is changed with supply of an electric current, a lens drive unit including one or more electrodes electrically connected to the refractive index-adjustable lens and a voltage adjusting unit capable of adjusting a voltage applied to the one or more electrodes, and a control unit that that controls the voltage adjusting unit such that a refractive index of the refractive index-adjustable lenses is adjusted, sets at least one training range within a refractive index adjustment range of the refractive index-adjustable lenses, and adjusts the refractive index of the refractive index-adjustable lenses in the training range.

This describes a treatment method for autism/ASD intended to encourage greater eye contact by affected children. The treatment method incorporates an artificial demonstration of the phenomenon of eye contact, and that method is described herein along with the principles of action of the treatment and the necessary procedure to perform it. Also described are two embodiments of the physical portion of the invention that can be used for the demonstration: first, an item in the form of a cuboid with animatronic eyes affixed to one side that most purely reflects the principles behind the treatment, and second, another in the form of a stuffed toy that is perhaps more practical.

Active dichoptic perceptual-learning tasks or dichoptic game play have been shown to significantly improve visual acuity of amblyopic children and adults. However, these dichoptic perceptual learning tasks are intensive and repetitive such that non-compliance is high. In contrast, the invention provides dichoptic perceptual learning in a manner that the user maintains its use and compliance is increased. Further, compliance becomes automatic if the user performs tasks in a normal manner and “forgets” that they are actually under-going treatment as it is integrated with minimal disruption to their life and activities. Accordingly, a methodology exploiting complementary dichoptic stimulation is presented.
