Optometry method based on VR technology and VR spectacle optometer

Abstract

The invention discloses an optometry method based on the VR technology and a VR spectacle optometer, and belongs to the technical field of optometry. The optometry method based on the VR technology comprises the following steps that (a) dedicated optometry images are established in a VR system, and a relation y=f(x) which is between a sharp image location x observed by human eyes and human eye power y is fit after sampling; (b) the image sharpness is adjusted through the adjustment of the image location by a user till a sharp image is observed; (c) cumulative image location information is recorded by an optometry algorithm, and the human eye power is calculated through the relation fit in step (a). The invention further discloses the VR spectacle optometer. The optometry method is simple, easy, reliable and stable, while the VR spectacle optometer has the advantages of light weight, convenience, easy mobility and low cost, and spectacles can be prescribed and bought in a self-service mode through the Internet, which is used with convenience.

Description

technical field [0001] The invention relates to an optometry method and a optometry instrument, and more specifically, to a VR glasses-based optometry method and a VR glasses optometry instrument. 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 differen...

AI Technical Summary

Problems solved by technology

[0004] 1. The error of measurement depends heavily on the precision of the optical path and machinery

[0005] 2. It depends heavily on the cooperation of human eyes

For example, the patient's head and eyes do not cooperate well, they move around, and their eyes are not focused enough on the cloud map of the refractometer (usually a clear picture of a small balloon or a small racing car), so that the relaxation and adjustment are not enough, resulting in irregular sampling rings. This will inevitably affect the accuracy of the diopter test results, and even the diopter of repeated checks varies greatly

[0006] 3. With 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

[0007] 4. The production cost of traditional optometry is expensive, and the cheapest price is around 15,000, which is not suitable for popularization and use by the whole people.

[0008] 5. Traditional refractometers are poorly adapted to the Internet, and it is inconvenient to complete optometry at home through the Internet
