[0051] The present invention provides a first embodiment of a visual training method, comprising:
[0052] Step 101, acquire the corrected visual acuity of both eyes and compare whether the corrected visual acuity of the two eyes is the same.
[0053] Compared with uncorrected vision, corrected vision is generally aimed at people with refractive errors. Uncorrected vision is your actual vision, and corrected vision is the vision obtained after correcting refractive errors with the eyes.
[0054] In other words, corrected vision is vision with glasses. Visual acuity measured without glasses is called uncorrected visual acuity. For example, a myopia patient's visual acuity is 0.1 without glasses, and the visual acuity is 1.5 after wearing glasses.
[0055]Step 102, when the corrected vision of the two eyes is different, control the two lenses in the VR head-display to perform different renderings of the images to be displayed, and then display images with different contents i...

[0062] The present invention provides a second embodiment of the visual training method, comprising:
[0063] Step 201, acquire the corrected visual acuity of both eyes and compare whether the corrected visual acuity of the two eyes is the same.
[0064] The content of step 201 is the same as that of step 101 in the first embodiment of the present application. For specific description, please refer to the content of step 101 in the first embodiment, and details are not repeated here.
[0065] Step 202, acquire the user's age.
[0066] It should be noted that there is no sequence between step 202 and step 201, and step 201 or step 202 may be performed first.
[0067] Step 203, when the corrected vision of the two eyes is different, obtain the preset parameters corresponding to the lower corrected vision, and control the two lenses in the VR headset to render the images to be displayed differently according to the preset parameters, and then perform different renderings on the ...

Abstract
The invention discloses a vision training method, device and equipment. The method comprises the steps of obtaining corrected visual acuity of two eyes of a user, and judging whether or not the visualacuity of one eye is equal to that of the other eye through comparison; when the visual acuity of one eye is different from that of the other eye, controlling two cameras in a VR headset display device to render images to be displayed differently, and then displaying the images with different contents in views of the two eyes to be recognized by the user, wherein compared with the image in the view of the eye with higher corrected visual acuity, the image in the view of the eye with lower corrected visual acuity has more objects and/or has an image background which is in a visual-stimulationdynamic change mode, and thus the image stimulation received by the eye with the lower corrected visual acuity is stronger than that received by the eye with the higher corrected visual acuity. Through the vision training method, device and equipment, the defect that only vision of the two eyes can be improved but the prohibition problem between the two eyes cannot be solved by training the two eyes with a cover method is overcome.
Description
technical field [0001] The invention relates to the technical field of virtual reality, in particular to a visual training method, device and equipment. Background technique [0002] Virtual reality (virtual reality, VR) virtual reality technology is a computer simulation system that can create and experience a virtual world. System emulation of physical and physical behavior immerses the user in the environment. [0003] Amblyopia refers to those who have no obvious organic lesions in the eyeball, but the corrected visual acuity of one or both eyes still cannot reach 0.8, which is called amblyopia. The main causes of amblyopia are visual inhibition and form deprivation. During the development of binocular vision, there is a competition mechanism in the visual center. Form deprivation makes the visual input of both eyes unequal. There is competition between the eye with more visual information input and the eye with less visual information input, and the eye with more visu...
