A method of improving stereopsis and devices for improving stereopsis in a patient, including facilitating development of a new stereo preferred retinal locus by presenting the patient with dichoptic images that require simultaneous use of both eyes to accomplish a visual task.

A miniaturised instrument for simulating simultaneous vision by generating masks is provided with a single image-forming optical channel. The instrument comprises: a mask-generating element (EGM) which generates at least two complementary masks, with a temporal frequency of alternation such that when one partially blocks the incident light, the other allows the incident light to partially pass, and vice-versa; an adjustable lens (LA) of variable optical power which generates, with said frequency of alternation, at least two different optical powers corresponding to at least two observation distances. The EGM and the LA are located in a single optical channel via which the incident light circulates, such that each mask of the EGM is temporally synchronised with a power of the LA. The combination of all the masks and optical powers produces, via high-speed temporal fusion, a pupil pattern wherein at least two optical powers corresponding to at least two observation distances are combined.

Provided herein is an orthoptic method of improving depth-perception in an individual. Devices, systems and kits for performing the present method are also provided.

A system for treating amblyopia through the visual stimulation of the brain through a predetermined regime is provided. The system for treating amblyopia comprises a headmountable visual content display device, a controller unit, a visual content source, a data storage device, a graphic processing unit and an audio source. A protocol useful for treating amblyopia by visual stimulation of the brain is also provided. A predetermined regime useful for treating amblyopia by stimulation of the brain is additionally provided.

Disclosed is a stereoscopic vision training providing apparatus including a display module, a memory including a first reference image, a second reference image, a plurality of training images, stereoscopic vision information, an input module that receives a response of a trainee, and a control module that outputs the first reference image to a first area of the display module, and outputs the second reference image to a second area of the display module, sets training coordinates based on a coordinate change signal for the first reference image and the second reference image, outputs the plurality of training images with different stereoscopic effects to the display module based on the training coordinates, and performs a stereoscopic vision training operation of receiving a selection response to a training image with a high stereoscopic effect.

The present invention relates to a method for providing visual perception training using visual perception learning, the method comprising the steps of: obtaining a field-of-view map having a plurality of unit regions to which a vision index reflecting a user's vision ability is assigned; providing a first session using a visual perception task which is performed by displaying a first visual object for central fixation of the user's field of view and a second visual object in the vicinity of the first visual object, and requests the user's response related to at least the second visual object; determining a vision ability changed region among the plurality of unit regions on the basis of the user's response from the first session; and providing a second session using the visual perception task.

A real time system for monitoring and optimizing patient adherence to digital therapy. The system can measure at least one of head stability, eye stability, gaze direction, head pose, facial expression, reading related eye movements, eye alignment stability, eye blink rate, attentive engagement, general engagement, emotional state, total eye stability, yawning and distance between the user and the camera. This information is provided as input to computer vision algorithms to generate a multi-dimensional representation of user attention and engagement. The system can alert the caregiver or health care professional if the patient disengages from the treatment and if the patient is sitting at the wrong distance from the treatment device. The system includes a camera, a processor, computer vision algorithms executed by the processor (a GPU processor), at least one digital display device, a loud speaker and an optional internet connection that can enable communication with other electronic devices.

An eye mounted display presents defocused images to patients to affect their eyeball development and control focusing disorders such as myopia or hyperopia. For example, images may be projected with peripheral myopic defocus in order to control myopia. Images may be projected with peripheral hyperopic defocus in order to control hyperopia.

An apparatus for screening, treatment, monitoring and/or assessment of visual impairments, comprising electronic means for simultaneously applying two separate and unrelated processing methods to images presented to a patient's eyes: a first processing method being applied to an non-amblyopic eye (the eye with the better vision), and a second processing method being applied to an amblyopic eye (the weaker eye, or the impaired eye). A method for screening, treatment, monitoring and/or assessment of visual impairments, comprising: a. defining a starting point, wherein differences between a patient's eyes are completely, or as closely as practically possible, corrected, to enable two identical or similar images to be transferred to the brain from the patient's eyes; b. defining an ending point, wherein there is no correction applied to any of the patient's eyes; c. defining a screening, treatment, monitoring and/or assessment plan, for initially applying correction to images according to the starting point, then gradually reducing the correction, at a controlled and predetermined rate, towards the ending point; and d. applying the plan to images presented to the patient's eyes, while monitoring patient's performance.

In various embodiments, methods of treating, improving, or preventing degradation of a user's vision incorporate the display of visual content dichoptically to the left and right eye of the user while the accommodative demand placed on the left eye and/or the right eye is altered.
