VR (Virtual Reality) eyesight correction method and device

Abstract

The invention discloses a VR (Virtual Reality) eyesight correction method and device. The device comprises a photographing assembly, a display screen, a self-adaptive visual range adjusting mechanism and a processor; the photographing assembly is used for acquiring video data of a realistic environment according to vision angles of human eyes and transmitting the video data to the processor; the processor is used for carrying out virtualized processing on the received video data to convert the video data into 3D (Three Dimensional) data of a virtual environment, transmitting the 3D data to the display screen and carrying out quantification processing on an induction signal to obtain a visual range adjusting signal; the display screen is used for displaying the virtual environment of the 3D data; the self-adaptive visual range adjusting mechanism comprises a lens, a sensor for acquiring a distance between a scene and the human eyes and generating the induction signal and a lens adjusting assembly which is used for adjusting the distance between the lens and the display screen according to the visual range adjusting signal. By adopting the VR eyesight correction method and device provided by the invention, the surgical risk of eyesight correction can be reduced and the eyesight correction effect can be improved.

Description

technical field [0001] The present invention relates to the technical field of VR, in particular to a VR vision correction method and device. Background technique [0002] Myopia and hyperopia are generally caused by excessive use of the eyes, which leads to loss of activity of eye muscles and reduced eye adjustment performance. When the eyes look at close-up objects for a long time, it will cause the ciliary body to press on the lens for a long time, causing the shape of the lens to become more curved. Under this pressure for a long time, it will cause irreversible changes in the lens. That is to say, the eyes see near and far, mainly through the ciliary muscle stretching or compressing the lens, that is, changing the diopter of the lens. The theory is that by looking at something far away for a long time, the ciliary muscle can stretch the lens to restore vision. [0003] At present, there are two main methods of vision correction: wearing glasses and laser surgery. For...

AI Technical Summary

Problems solved by technology

For the treatment plan of laser surgery, this plan can cure myopia, but laser surgery has risks and the possibility of recurrence; for the plan of wearing glasses, wearing ordinary myopia and hyperopia glasses cannot fundamentally solve the problem, but the longer the time, the degree of myopia will be deepened

In addition, there are also various auxiliary treatment devices for myopia in the market, but most of them are inconvenient to use or the effect is not obvious.
