Intelligent vision testing system

Abstract

The invention discloses an intelligent vision testing system. The intelligent vision testing system comprises an input unit, a storage unit, a distance sensor, a processing unit and a data server, wherein the processing unit is connected with the input unit, the storage unit, a display unit and the distance sensor; the data server is connected with the display unit and the processing unit. According to the intelligent vision testing system, the detection answer information of a tested person is analyzed, the analysis result is transmitted to the display unit or printed, and if the information entry of the tested person is not the first time, the data server compares the current detection answer of the tested person with the last-time detection result, analyzes, and transmits the analysis result to the display unit or prints the analysis result. According to the intelligent vision testing system, the data analysis result is available, and the analysis result obtained by tracking the vision change of the tested person is also available, meanwhile, the tested person does not need to stand at a position with the fixed distance away from a visual chart for testing, the intelligent vision testing system can carry out the testing with the distance between the tested person and the visual chart changing aiming at the tested hyperopia and myopia persons, and the accuracy of the testing result is improved.

Description

technical field [0001] The invention relates to an intelligent vision detection system. Background technique [0002] Vision refers to the ability of the eyes to distinguish objects. Good vision is very important for people's work and life. In order to maintain good vision and detect eye diseases early, vision testing is required. The traditional method of visual acuity test is usually to use the international standard visual acuity chart, the international standard visual acuity chart is composed of 12 rows of "E" optotypes with different sizes and opening directions, and the "E" optotypes of different sizes correspond to different visual acuity levels. When using the international standard eye chart to test vision, the tester stands 5 meters away from the international standard eye chart, the medical staff indicates different "E" optotypes, and the tester answers the opening direction of the "E" optotype indicated by the medical staff. The personnel judge the tester's vis...

Problems solved by technology

The eyesight judged by the doctor can only give the eyesight level, not only does not have the specific data analysis results and the analysis results of tracking the changes in the eyesight of the tester, but also the tested person can only stand at a fixed distance from the eye chart for testing, and cannot For hyperopia and nearsighted subjects, the distance change test between the subject and the eye chart affects the accuracy of the test results
