VR glasses and degree-of-myopia adjusting method thereof

Abstract

The embodiments of the invention provide a pair of VR glasses and a degree-of-myopia adjusting method thereof, which relate to the technical field of intelligent wearing. The pair of VR glasses enables myopia users to see a virtual image clearly, and is simple to operate. The pair of VR glasses comprises a glasses body, and a lens, a display screen and a control module which are arranged on the glasses body. The control module is used for controlling display of the display screen. The pair of VR glasses further comprises a driving module and a driving controller which are arranged on the glasses body. The driving module is used for driving the lens to move under the control of the driving controller in order to adjust the distance between the lens and the display screen. The control module is further used for making the display screen display a degree-of-myopia selection interface, and the degree-of-myopia selection interface displays a variety of degree options from 0. According to the selected degree of myopia, the driving controller controls the driving module in order to make the distance between the lens and the display screen correspond to the selected degree of myopia so that the picture displayed by the display screen is within the photopic vision distance range of the human eyes.

Description

technical field [0001] The invention relates to the field of smart wear technology, in particular to VR glasses and a method for adjusting their diopter. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) glasses use a head-mounted display device to close the user's vision and hearing to the outside world, and guide the user to have a feeling of being in a virtual environment. The display principle is to use the lens to make the screen of the display screen become an upright and enlarged virtual image, and the image generated by the display screen is magnified by the optical system to be viewed from a distance. What the human eye sees is a virtual image similar to the screen on a large screen. [0003] After passing through the refractive system of the normal human eye, the parallel rays of light focus exactly at the fovea of ​​the retina. Under suitable lighting conditions, the normal human eye can see objects at infinity. Myopia can only se...

Problems solved by technology

[0003] After passing through the refractive system of the normal human eye, the parallel rays of light focus exactly at the fovea of ​​the retina. Under suitable lighting conditions, the normal human eye can see objects at infinity. Myopia can only see objects within a certain distance, and the distance of clear vision is correspondingly shortened. When a myopic user wears VR glasses, the virtual image is still outside the clear vision distance of normal human eyes. For myopic users Generally speaking, the distance between the virtual image and the eyes is too large, which makes the picture seen by myopia users blurred, which greatly reduces the viewing experience of myopia users.

[0004] At present, for myopia users, VR glasses have proposed three solutions: First, expand the space where VR glasses and human eyes fit together to accommodate the user's myopia glasses. Although myopia users can see virtual images clearly through this solution, but Too much space will not only increase the volum
