Description
technical field [0001] The invention relates to the field of medical technology, in particular to vision testing equipment. Background technique [0002] With the development of modern technology, people spend more and more time using electronic products, thus causing different degrees of visual impairment and need to wear glasses. For the audience of glasses, the main group is those who need glasses due to myopia, and a considerable number of people have problems such as hyperopia and astigmatism. Since the structure of the human eyeball is very precise, the requirements for precision are also very high when dispensing glasses, and it is necessary to be very accurate when adjusting the prescription. [0003] However, in the prior art, there are problems that the accuracy of adjusting the instrument is not high enough and the adjustment of the forward tilt angle is not accurate enough to affect the measurement accuracy during the vision test, which affects the visual sense....
