Human vision monitor

Abstract

The invention discloses a human vision monitor which comprises a transmitting unit, a monitoring unit and a power controller. The monitoring unit comprises a receiving unit, a clock circuit, a memory card, a data processor, a display screen and an EEPROM (electrically erasable programmable read-only memory), and the data processor is used as a core element of the monitoring unit and is used for analyzing data and exchanging the data. The human vision monitor has the advantages that vision tests can be independently completed for users in real time by the aid of the monitor, vision test results can be stored, and vision conditions in a period of time can be retrieved according to requirements of the users, so that the users can conveniently query vision change conditions in the period of time; the users can observe the vision change conditions in the period of time while the vision of the users is monitored, so that a vision change warning effect can be realized for the users; the vision of the users can be conveniently tested by the aid of the human vision monitor, the test results are accurate, and the vision change conditions can be tracked for a long time owing to a data echoing function of the human vision monitor.

Description

technical field [0001] The invention relates to the technical field of visual acuity detection, in particular to a human eye visual acuity monitor. Background technique [0002] Eyesight detection is the most basic measurement method to reflect the quality of the human eye's visual function, and it is the embodiment of the human eye's ability to distinguish small objects. [0003] my country is a big country with myopia. According to the survey results of the Ministry of Education in 2010, the incidence of myopia among high school students in my country is 79.20%, and there are as many as 400 million people with myopia nationwide. Myopia is a progressive disease, prevention and protection are very important, and the detection of human vision is an essential link. At present, the most commonly used tool for testing eyesight is the eye chart light box. When performing a vision test, it needs the guidance of professionals to complete the test. Moreover, the visual acuity of t...

Problems solved by technology

[0005] In view of this, the present invention provides a human eye vision monitor to overcome the fact that the vision detection tools in the prior art need to be used by multiple people, and the position of the visual target is fixed, which may easily lead to inaccurate vision detection results, and at the same time, it is impossible to detect The results are stored, so that the monitoring of human vision cannot be realized, and the problem of early detection and early treatment cannot be achieved.
