Problems solved by technology
[0003] At present, most AR devices, except for the external ambient light that can enter the human eye, can only receive information from one display screen with one eye, so they can only use the conventional binocular parallax display method to form stereoscopic vision. Inevitably, the problem of convergence adjustment conflicts will seriously affect the user's wearing experience

The invention discloses a zoom device, AR (Augmented Reality) equipment and a myopia correction method. The zooming device of the embodiment is applied to the AR equipment, and comprises: a display assembly used for outputting circularly polarized light; a lens assembly which is located on the light emitting side of the display assembly, wherein the optical axis of the lens assembly is perpendicular to the light emitting face of the display assembly, and the lens assembly at least comprises a first lens and a second lens; a switching assembly which is located in the lens assembly and used for responding to a switching instruction to switch the phase state of the zooming device so that the lens assembly can modulate the modulation light path of the circular polarized light to change, and therefore the image plane image displayed by the zooming device can change. According to the zooming device provided by the embodiment of the invention, the modulation light path is changed through the change of the phase state, so that the purpose of quickly switching the image plane image displayed by the zoom device is realized, the whole process is convenient and quick, the display function of a single-eye multi-layer focal plane can be realized, and the whole device has the characteristics of simple structure and low cost.
Description
technical field [0001] The present invention relates to the field of AR technology, in particular to a zoom device, AR equipment and a myopia correction method. Background technique [0002] With the development of display technology, such as virtual reality (Virtual Reality, VR) display devices and augmented reality (Augmented Reality, AR) display devices have been widely recognized by users and widely concerned by the industry. Virtual reality devices have immersion (Immersion), interactive Interaction and imagination (Imagination) and other advantages; the augmented reality display device can realize the fusion of the external real scene and the virtual scene by superimposing the displayed virtual scene image on the external real scene, and thus can enhance the user's understanding of the real world. cognitive ability. [0003] At present, most AR devices, except for the external ambient light that can enter the human eye, can only receive information from one display sc...
