Embodiment Construction

[0057] Based on the virtual reality glasses, the present invention proposes a vision correction method and a vision correction device. While using the virtual reality glasses, the eye muscles can be strengthened, and the active feedback loop effect can be restored by reactivating and strengthening the ciliary muscles. This reduces reliance on secondary feedback loops, and eventually the longitudinal length of the eyeball will return to normal. Thereby fundamentally realize the purpose of curing refractive errors.

[0058] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] refer to Figure 4 , as a preferred embodiment of the present invention, a vision correction method, comprising:

[0060] Determine the visual range of patients with refractive errors;

[0061] Controlling the...

Abstract

The invention provides a vision correction method. The vision correction method comprises the steps that a visible range of an ametropia patient is determined; the imaging position of a virtual image in a pair of virtual reality glasses is controlled, so that when the ametropia patient wears the virtual reality glasses to view the virtual image, the virtual image can be clearly imaged on the retinas of the eyes of the patient; based on the visible range, the imaging position of the virtual image is periodically adjusted to exercise the eye muscles of the patient and correct vision. In addition, the invention also provides a vision correction device. The vision correction device comprises a pair of virtual reality glasses, a data determining unit, a central control unit and an adjusting unit. By adopting the vision correction method and the vision correction device, the imaging position of the virtual image can be accurately controlled, and the eye muscles are exercised by periodically changing the position in the vision range of the patient. Functional rehabilitation of the ciliary muscle can be also achieved, natural vision rehabilitation is finally achieved, and the purpose of treating ametropia is achieved.

Description

[0001] 【Technical field】 [0002] The present invention relates to a method and a device for correcting vision, in particular to a method for correcting vision based on VR glasses and a device for correcting vision. [0003] 【Background technique】 [0004] With the rise of virtual reality (Virtual Reality, VR) equipment, there are various types of virtual reality glasses on the market, that is, VR glasses, which can also become VR helmets. The structure of these VR glasses is generally a lens + display imaging method. The lens is in front of the user's eyes, and the display screen is located within the focal length range of the lens. The image played on the display screen generates a magnified virtual image through the optical principle of the lens, so that the user can see the virtual image through the lens. The positions of lenses and display screens in general VR glasses are fixed, basically based on the visual range of users with normal vision. But the diopter of eyes of ...
