Optometry method based on VR technology

Abstract

The invention relates to an optometry method based on the VR technology. The method includes the following steps of S1, outputting optometry information to a user, wherein the optometry information includes a plurality of optometry special images; S2, sequentially displaying the optometry special images so that the user can select the clearest optometry special image as a target image; S3, obtaining a human eye myopic degree corresponding to the target image from a database of a VR system. By establishing the associated information between the optometry special images and the human eye myopicdegree in the VR system and selecting the clearest optometry special image as the target image through human eyes, the human eye myopic degree is determined; compared with a traditional optometry unit, an optical path is not used, the optometry method is simple and easy to use, and self-service optometry can be rapidly and conveniently conducted.

Description

technical field [0001] The invention relates to the technical field of optometry, in particular to an optometry method based on VR technology. Background technique [0002] The traditional optometry is to use the optical path (an optical device with specific properties) to test optometry, that is, to measure the degree of a person's eyes, to determine whether there is astigmatism and the corresponding axis position when there is astigmatism, etc. The principle of the optical path is to emit visible light through one end of the device, pass through a series of concave-convex lenses, and then enter the human eye, and then reflect the corresponding reflected light through the pupil surface of the human eye, and the reflected light passes through a series of concave-convex lenses. After passing through an aperture mirror diaphragm, it will be focused at the other end of the optical path to form a halo. For eyes with different degrees, auras of different sizes will be formed.

Problems solved by technology

The advantage of this method is that the measurement is more accurate, but there are many disadvantages; for example, it depends heavily on the degree of cooperation of the human eye; the optical path plus other peripheral equipment such as the fuselage, the weight of the optometry instrument is about 25kg, which is clumsy and not suitable for mobile optometry; The production cost of optometry is expensive, and the cheapest price is around 15,000, which is not suitable for the general public
