In one or more embodiments, the diopter value increment between any two successive magnifiers of the set is equal to K(0.1) log, where K is an integer>0 or a fraction whose denominator is an integer>0. In one or more embodiments, one or more elements of the set are packaged for sale. In some embodiments, a set of optical, telescopic, or electronic magnification devices may be provided, the set including one or more devices configured to provide non-rectilinear magnification.

A fully wearable, wireless soft electronic system that offers a portable, highly sensitive tracking of eye movements (vergence) via the combination of skin-conformal sensors and a virtual reality system. Advancement of material processing and printing technologies based on aerosol jet printing enables reliable manufacturing of skin-like sensors, while the flexible hybrid circuit based on elastomer and chip integration allows comfortable integration with a user's head. Analytical and computational study of a data classification algorithm provides a highly accurate tool for real-time detection and classification of ocular motions. In vivo demonstration with 14 human subjects captures the potential of the wearable electronics as a portable therapy system, whose minimized form factor facilitates seamless interplay with traditional wearable hardware.

Disclosed is a wearable optical devices for a human subject, comprising: a transparent lens; a wearable frame configured to maintain the lens in front of an eye of a human subject; a transparent pixelated active optical element where the pixels of the active optical element have an optical property with a changeable value; an eye tracker; and a controller configured to set a value for an optical property of the pixels of the active optical element so as to create an image mask through which at least some of the light reaching the feye passes through, thereby modifying the image formed on the retina of the first eye.

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.

The current subject matter relates to rehabilitation using a content guide for viewing video, for example as a vision rehabilitation aid for individuals with hemianopia or as a rehabilitation aid for individuals with attention disorders. The current subject matter includes providing video in which a region of interest of the image is specified with a marker, referred to herein as a content guide. The content guide can include a circle surrounding the region of interest. By providing video with a content guide to direct viewers to a region of interest in the video, information acquisition by the viewers is improved. Such an approach can aid individuals with vision deficits or attention disorders. The current subject matter can also be used as a therapy for spatial neglect. Related apparatus, systems, techniques and articles are also described.

Systems and methods for treating myopia are provided. A system may include a digital apparatus, which may include a digital instruction generation unit configured to generate digital therapeutic modules for treating myopia based on a mechanism of action (MOA) in and a therapeutic hypothesis for the myopia, generate specified digital instructions based on the digital therapeutic modules and provide the digital instructions to a first user, and an outcome collection unit configured to collect the first user's execution outcomes of the digital instructions. The system may also include a healthcare provider portal for a healthcare provider to manage their patients and/or an administrative portal.

An apparatus to treat refractive error of the eye comprises one or more optics configured to project stimuli comprising out of focus images onto the peripheral retina outside the macula. While the stimuli can be configured in many ways, in some embodiments the stimuli are arranged to decrease interference with central vison such as macular vision. The stimuli can be out of focus images may comprise an amount of defocus within a range from about 3 Diopters (“D”) to about 6 D. In some embodiments, the brightness of the stimuli is greater than a brightness of background illumination by an appropriate amount such as at least 3 times the background brightness. In some embodiments, each of a plurality of stimuli comprises a spatial frequency distribution with an amplitude profile having spatial frequencies within a range from about range of 1×10.sup.−1 to 2.5×10.sup.1 cycles per degree.

A method for improving vision utilizes a progressive series of various diopter eyeglasses, a vision chart or the like, and textual material. The first therapy commences with the person donning a first pair of eyeglasses having a magnifying diopter and the vision chart is positioned approximately 2 feet away from the person. The person then fixates upon the chart mark until the chart mark becomes visually clear. The person then moves farther away from the vision chart by approximately one foot and the person once again fixates upon the chart mark until the chart mark becomes visually clear. The second therapy commences with the person donning a first pair of eyeglasses having a low magnifying diopter and then reading textual material for several minutes. The person then replaces the low magnifying diopter eyeglass with a higher magnifying diopter eyeglass and once again reads the text for several minutes.

Computer-implemented system and method that allows for the rehabilitation of individuals with strabismus by leveraging commercially available VR headset technology. Eye tracking capabilities and external cameras of existing VR headsets, enables the system and method to first gather the image that the dominant, unaffected eye is focused on (FIG. 1). Then, given where the strabismus unaffected eye's gaze falls on its screen, the system and method will take the image and identify where that point lies on the strabismus affected eye's screen. This point is the ideal gaze point of the strabismus affected eye. The software solution disclosed herein will then warp the strabismus affected eye's screen so that this new gaze will line up with the unaffected eye's gaze.
