Description

technical field [0001] The invention relates to a vision detector for children, which belongs to the technical field of medical devices. [0002] Background technique [0003] At present, the basic tool used in vision testing is an eye chart with the word "E" printed on it. The "E" chart is arranged in rows of different sizes, and the opening orientation of each row of "E" is different. 1. During the vision test, the examinee is kept at a specified distance from the eye chart, and the degree of vision can be determined by identifying the opening direction of the word "E" in each line. Although this vision inspection tool has the advantages of simple structure, easy to use, and low cost, if this kind of tool is used to perform vision inspection on children, especially young children, due to the poor comprehension ability of children and young children including self-control ability, in addition Eye examination is boring and tasteless, so it is not only time-consuming and la...
