Human eye vision monitoring system and method

Abstract

The invention discloses a human eye vision monitoring system and method. The system comprises an intelligent terminal for graph display and human-computer interaction, a portable optometry unit for changing an optical path to complete measuring of each performance parameter of eyes and a server for analyzing and evaluating vision of a testee according to data sent by the intelligent terminal, andthe intelligent terminal is embedded at the starting end of the optical path of the portable optometry unit and is in data communication with the portable optometry unit and the server in a wireless or wired manner. The system can record measurement values of eye diopter and vision within a period of time and display changing trend of all measurement values within the period of time so as to realize evaluation and prediction of visual quality, can timely find the process of changing from pseudomyopia to real myopia and achieve the objective of restoring emmetropia by timely training and intervening a visual system at the stage of pseudomyopia and has good effect on preventing myopia of teenagers.

Description

technical field [0001] The invention relates to the technical field of optical equipment, in particular to a system and method for monitoring the development state of human vision. Background technique [0002] The visual system of the human eye is composed of cornea, aqueous humor, lens, vitreous body, retina and optic nerve. The light entering the eye is refracted by the refractive system of the eye and then focused on the retina. After the visual cells on the retina feel the light, the visual information is transmitted to the visual cortex, and vision is formed after processing. The axial length of a normal eye is about 24mm, and the refractive power is about 60D. Among them, the cornea accounts for about 75% of the diopter of the whole eye, and is the most important refractive part. The lens itself is elastic, and under the pulling action of the ciliary muscle and the suspensory ligament, it can change the curvature of the surface, change its refractive power, realize t...

Problems solved by technology

[0008] However, the collection of data related to vision health and the detection of the refractive state of the eyes are time-consuming and laborious. It is almost meaningless to use only the E vision chart; if accurate collection is required, large and expensive instruments need to be used in ophthalmology hospitals or outpatient clinics It is carried out with complex means, and professional technicians are required to interact with the testee during the detection process. The cost of manpower and material resources is very high, and it is difficult to apply to people who are younger or have hearing impairment. In addition, this detection method does not It is conducive to the high-frequency detection and evaluation of vision, and it is difficult to detect early detection of refractive error defects (especially myopia)
