This invention relates to the field of rehabilitation training technology, and discloses a method for determining amblyopia perception training data and amblyopia perception training visual targets. The method includes: acquiring test data of the target subject, wherein the test data is data obtained from a basic amblyopia perception test of the target subject; determining the initial contrast sensitivity data of the target subject based on the test data; acquiring reference contrast sensitivity data, wherein the reference contrast sensitivity data is obtained from amblyopia perception tests of healthy subjects of the same age as the target subject; determining the target subject's weak data based on the initial contrast sensitivity data and the reference contrast sensitivity data; and determining the target subject's training data based on the weak data. This invention focuses on targeted training in weak areas, reducing ineffective training in normal areas, saving a significant amount of unnecessary training time, and improving the efficiency and targeting of amblyopia perception training.

Embodiments of the present disclosure disclose an eye movement tracking-based amblyopia training video display system. A specific implementation of the system includes an interaction processor, a central processor, a visual display processor and a user-side screen; and the interaction processor is configured to obtain a screen gaze point coordinate of a target user; the central processor is configured to determine a target gaze point area corresponding to the screen gaze point coordinate; the visual display processor is configured to perform differential update processing on first display content and second display content in the target gaze point area; insert visual stimulation information in the first display content corresponding to a first eye in the target gaze point area, and perform corresponding update processing on the second display content corresponding to a second eye. The implementation can improve the personalization and real-time response capability of amblyopia training, reduce the training period of amblyopia training, and reduce the occupation of display bandwidth and image processing resources.

The utility model belongs to optical device technical field, concretely relates to a kind of lens and glasses, the lens includes: mirror surface, the mirror surface is provided with the multiple paths of fitting hyperbolic space, and path distribution is more dense at the area closer to the edge of lens;Microstructure includes multiple micro-lenses distributed according to predetermined rule;The distribution of the microstructure makes that the contrast of eye-in image adapts to the non-uniform distribution of visual influence cell in retina, including the microstructure is along the multiple paths setting;Or setting in the area surrounded by path;The power of the micro-lens gradually increases along the radial outward direction of lens center direction.By the above setting to improve amblyopia while improving experience.

A system for the dichoptic treatment of amblyopia comprising a source of binocular images having a difference in information content, such as a different signal to noise ratio, between left and right eye images; and a source of sounds corresponding to a direction with respect to a user, wherein a perceived directionality of the sound by the first user corresponds to a direction of a visual object within the binocular images.

The application provides a weak vision training method and system based on superposition of visual stimulation and body movement, and relates to the technical field of visual function training. An original visual image is displayed on a virtual reality display device, and a weak vision user to be trained watches the original visual image by using binoculars; visual stimulation content is superposed on the original visual image, so that the visual content observed by the weak eye and the strong eye of the weak vision user to be trained is different, the visual content observed by the weak eye is stimulated more strongly than the visual content observed by the strong eye, and the difference between the visual content stimulated by the strong eye and the weak eye makes the two eyes balanced; specific body movement training instructions are issued during the training process, and corresponding visual effects of the specific body movement are superposed when the user completes the specific body movement. While promoting the coordination of the two eyes, the visual stimulation content is used as an attention improvement tool to promote the visual-body-vestibular integration of the user, and the compliance of the weak vision user to be trained in the training and treatment is enhanced.
