Illusionary motion-in-depth for vision therapy or entertainment is provided by altering the positional disparity by relative speed of movement and/or delay of movement of images of an image pair in motion which are viewed on a digital display device by stereoscopic means.

This describes a treatment method for autism/ASD intended to induce greater intrinsic motivation to make eye contact in 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 a therapy tool that can be used to effect the demonstration: first, an item in the form of a cuboid with animatronic eyes affixed to one side, and second, another in the form of a stuffed dog.

An embodiment provides a vision training device having excellent vision training efficiency based on personal vision. An embodiment 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.

The method relates to the field of ophthalmology and is intended for postoperative restoring bifoveal fusion in patients, inter alia in children, following concomitant esotropia surgery, with use of liquid crystal glasses. The technical effect of the invention is restoration of bifoveal fusion in accordance with individual ocular motility parameters, using anharmonical alternating of liquid crystal glasses. The technical effect is achieved by the approach during which for patients with a residual angle of deviation of less than 10 degrees after esotropia surgery, a duration of the fixative eye movement of the eyeball (t in ms) is determined for each eye using a Gazelab video eye tracking device produced by BCN Innova (Spain), a duration of occlusion is then calculated in ms for each eye, using the formula: t=40+U, where t is the duration of occlusion in ms; 40 is the minimum time required for visualization between alternations in ms; U is the duration of the fixative eye movement in ms, and the duration of occlusion is set for each eye on liquid crystal glasses that are worn for 6-8 hours a day during 6 to 12 months.

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.
