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.

A method of assessing a presence and/or severity of at least one of diplopia and convergence insufficiency disorder of a patient; it includes providing a patient with an image pair configured to present a first image to a first eye of the patient and a second image to a second eye of the patient; obtaining performance information of the patient when the patient performs a task requiring the perceiving of the information content of the first image and the information content of the second image; adjusting, based on the performance information, the difference of the at least one image parameter between the first image and the second image; and assessing the degree of at least one of the diplopia and convergence insufficiency disorder of the patient based on performance information of the patient when the patient performs the task following the adjusting.

A vibration device 10 includes top plate assembly 12 defining cavity 27 therein that is configured and dimensioned to receive actuator plate 19 such that the actuator plate 19 is in direct contact with the top plate assembly 12. The actuator plate 19 transmits thereby a vibration signal represented by an oscillating vibratory force to the top plate assembly 12 to operate the oscillating vibration device. Vibration device 10 further includes base plate assembly 14 for the vibration device 10. The top plate assembly 12 is configured and dimensioned to be mounted on the base plate assembly 14. The base plate assembly 14 includes actuator mounting assembly 20 that is configured to receive actuator 50 generating a vibration signal represented by an oscillating vibratory force. A method of operating the oscillating vibration device 10 includes transmitting a vibration signal represented by an oscillating vibratory force to foot plate assembly 12.

Embodiments for systems, methods and apparatuses of eyewear are disclosed. One method includes treating a patient with shutter glasses therapy for a relatively short period of time, such as at least a 6 week period; wherein the shutter glasses therapy includes blanking a first lens of shutter glasses being worn by the patient for a first blocking time, blanking a second lens of the shutter glasses being worn by the patient for a second blocking time, and controllably setting at least one of the first blocking time and the second blocking time.

The present invention relates to a method for modifying at least one video frame of a digital video stream to be displayed on a display area. Each correction scheme has one or more specific digital filters based on visual defects perceived by a person with respect to a video frame portion, is configured when predetermined conditions are met and reconfigured whenever the origin position of an eye reference system associated with a respective eye is different from the position of the same origin in said predetermined conditions and/or the orientation of said eye reference system is different from the orientation of the same eye reference system in said predetermined conditions. The generation of a multiview digital video stream, subsequent to the application of the first correction scheme and/or the second correction scheme, and the displaying of said digital video stream by a multiview stereoscopic or stereoscopic video system allow to the two eyes of a person to observe a respective succession of video frames, wherein the content of the video frames of each sequence of video frames has been modified on the basis of visual defects of a respective eye of said subject suffering from a degenerative disease of the retina, so that said subject has a visual perception, in binocular vision, improved or corrected.

A system for training visual acuity includes an audio player and a controller. The audio player includes a database which stores plural pieces of music, and a headphone with which a user listens to the pieces of music so as to stimulate a visual cortex of the user, where each of the pieces of music contains two audio frequency components that have a frequency difference therebetween ranging from 1 to 45 Hz. The controller is electrically connected to the audio player, and is configured to control the audio player to play the pieces of music.

The present invention provides a computerized operator-controlled optical system and method for tracking eye exercises of a patient, the system including an optical tracking device adapted to allow an operator to track eye exercises of a patient, a patient-activated apparatus for performing eye exercises of binocular vision and a processor adapted to receive data from the optical tracking device and from the patient-activated apparatus thereby providing the operator with at least one indication of the eye exercises of the patient over time.

An eyesight training device and a method therefor are provided. The device includes a binocular visual-field separation device, including a double-separation plate assembly and an adjustable unit, the double-separation plate assembly including two separation plates which are movably connected to form an included angle, and the adjustable unit is used for adjusting the included angle between the two separation plates; and a display screen, wherein the double-separation plate assembly separates the display screen into a left visual field and a right visual field. The method includes: arranging two separation plates at a near-screen side; providing at least one movable training visual target at each of the left and right sides of the separated display screen, respectively; when divergent fusional ability of the trainee's brain visual center reaches its limit, the two training visual targets return along original paths to their starting positions, respectively, and repeating the process at least twice.

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.

An eyesight training device for cognition correction which includes a display unit; a user input unit; and a controller for controlling the display unit to overlap a recognition restraining image, which restrains a visual recognition of a recognition image, with the recognition image and to gradually change a concentration value of the recognition restraining image, and for storing, as recognition level information, information corresponding to a concentration value of the recognition restraining image as of a time when a visibility change confirmation input is input through the user input unit of the visibility change confirmation input is input.
