Self-focusing VR helmet

Abstract

The invention discloses a self-focusing VR helmet comprising a focusable lens group and a micro motor. The focusable lens group comprises a left eye lens and a right eye lens. The left eye lens and the right eye lens of the focusable lens group are respectively corresponding to the left eye and the right eye of a user under the wearing state of the helmet. The left eye lens and the right eye lens respectively comprise a lens or are respectively composed of at least two lenses through lamination. Both of the left eye lens and the right eye lens at least comprise a multifocal lens. According to the self-focusing VR helmet, the focusable binocular lens group is formed by one or multiple multifocal lenses through lamination; and a gear is driven by rotation of the micro motor, the gear is adaptive to the focusable lens group binocular lenses in a linkage way by the micro motor and the corresponding lenses are rotated to the appropriate position to realize the focusing function and complete self-focusing. Therefore, the myopia patients are enabled to experience the VR helmet with naked eyes and acquire the same experience effect with that of people with normal vision.

Description

Problems solved by technology

The first method of customizing the eyepiece will increase the production cost of the manufacturer, leading to an increase in the price of VR helmets, which is not conducive to the entry of VR helmets into the lives of ordinary consumers, and is also not conducive to the protection of consumers' personal information.

The second method is to increase the contact space between the helmet and the eyeball so that consumers can wear VR headsets with glasses. This will reduce the comfort of wearing the helmet and reduce the fidelity of the virtual scene on the other hand.

The third method is to adjust the focal length by adjusting the distance between the display screen and the eyepiece. This method has a certain limit on the focusing range. After focusing, problems such as aberration distortion, image distortion, and narrowing of the field of view may occur.
