Vision test method

Abstract

The invention belongs to the technical field of medical instruments, aims to solve the problem that an existing vision test method is inconvenient and has a complex process and provides a vision test method. The method includes storing vision test questions in a storage unit; reading the vision test questions by a reading unit; displaying the vision test questions by a display unit; allowing a testee to answer the vision test questions through a user input unit; allowing a receiving unit to receive the testee's answers and send these answers to a processing unit; allowing the processing unit to process the testee's answers to obtain vision test results, and transmitting the vision test results to a display unit for displaying; allowing the processing unit to send the testee's answers to a data server which stores the testee's answers. The vision test method has few steps, the testee can finish a vision test alone, and using is very convenient.

technical field

[0001] The invention belongs to the technical field of medical testing, and in particular relates to a vision testing method. 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 an international standard visual acuity chart, which is composed of 12 rows of "E" visual targets with different sizes and opening directions. Different sizes of "E" visual targets 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 th...
