Embodiment Construction

[0040] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0041] The retina will have local lesions due to various reasons, so that the position corresponding to the local retinal damage within the line of sight cannot be imaged. In the prior art, the problem of visual function impairment caused by partial retinal damage is mostly treated or eliminated by means of medicine and surgical treatment to eliminate the local retinal damage. The inventor found in the research that the visual function can be adjusted non-invasively through visual stimulation to gradually improve or restore the visual function.

[0042] The principle of the present invention is explained first below: people's binocular stereo vision is formed in this way: both eyes watch a certain object simultaneously, and the sight lines of both eyes i...

Abstract

Embodiments of the present invention provide a method and device for adjusting visual function, and a virtual reality head-mounted display device, wherein the method includes: respectively performing imaging on both eyes of the user to display images in corresponding local areas of the two eyes Corresponding preset map, and make the corresponding preset map have a preset time interval α between the respective imaging times of both eyes; wherein the local area corresponds to a partial retinal damage in one of the eyes, Moreover, the imaging time of the preset image in one eye corresponding to the partial retinal damage is earlier than the imaging time of the other eye of the preset image by a time interval α.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a visual function adjustment method and device, and a virtual reality head-mounted display device. Background technique [0002] Vision is undoubtedly of paramount importance, and the retina is a vital part of imaging. Each binocular cell in the visual cortex receives input from the retinas of the left and right eyes. The visual images formed by the retina are encoded by neurons in different visual centers to form neural images in the visual cortex. Human visual perception relies heavily on the latter. The neural circuits in the visual cortex have strong plasticity, and appropriate visual stimulation on the retina can gradually restore the visual function of the neural circuits in the corresponding cortical regions. The retina is divided into a foveal and a peripheral area; the foveal is the most sensitive area of ​​vision (color perception, resolution) in the retina. Tak...
