Background
The image-checking optometry method is an optometry method for judging the refractive states (emmetropia, myopia, hyperopia and astigmatism) by utilizing the brightness and motion rules of images formed after light rays are reflected by retina, and the basic principle is to search the far point position of an eye to be checked, correct the far point to a peephole of a video scope and determine the refractive state of the eye to be checked by observing the movement direction, speed, brightness and form of the reflected light. The optometry of the shadowgraph mirror is a common clinical ophthalmology and optometry method for objectively inspecting the refractive state of human eyes, and is also an effective ametropia inspection means for special groups.
Specifically, the image testing and optometry are also a relatively complex process, and can be gradually mastered only by repeated practice of optometrists and continuous summary of experience, so that the error is reduced, and the accuracy of optometry is improved; however, the optometry instruments widely used at present can only see the optometry image of the eye to be examined by an optometrist himself, and a beginner cannot obtain some feasible guidance, so that the growth period is prolonged; in addition, some optometry instruments exist in the prior use, and can transmit optometry images to a computer through a camera, but due to the limitation of the camera, the imaging is not accurate, and the manufacturing cost is high.
During the course of an optometry procedure, the eyepiece needs to be changed constantly to determine the lens power appropriate for the patient.
