Abstract

The invention discloses an intelligent vision inspection instrument, which is provided with a handheld remote control and a host part, wherein the host part displays a visual target randomly; a tester detects at the standard distance and transmits an infrared signal to the host by pressing a direction key corresponding to a self-considered visual target direction on the handheld remote control; an infrared data receiving unit in the host part receives the infrared signal transmitted from the handheld remote control and sends the infrared signal into a comparator so as to judge whether the judgment of the tester is correct or not; a data processing unit sends a comparison result into a sub-user detection result storage unit and a tester storage unit corresponding to the tester; and after multi-time testing, the tester not only can know the current own vision but also can master the vision change tendency within a certain time, thereby providing a reliable basis for preventing myopia for youngsters and monitoring the vision change of patients with eye diseases. The intelligent vision inspection instrument can be used without help of other people, and therefore the intelligent vision inspection instrument is convenient to use.

Description

Technical field [0001] The invention relates to an intelligent vision tester, which is suitable for visual tracking and measurement of children and adults physical examination, monitoring the brightness and time of reading and writing environment, etc., prompting healthy eyes, preventing myopia, and can also be used for screening visual disorders and eye diseases. All aspects of patient vision change monitoring and clinical diagnosis and treatment of optometry. Background technique [0002] Since 1985, my country has conducted a total of 4 national health surveys on adolescents. The survey shows that in recent years, the physical fitness of Chinese adolescents has continued to decline, the detection rate of poor eyesight is still high, and the incidence of poor eyesight of students is increasing year by year. Myopia has become an important issue affecting the health of our people. According to the preliminary survey of the child myopia prevention and control research project joi...
