The invention discloses an eyesight test method which includes the steps: adjusting the positional relationship between an eyesight test device and a patient and locking a target position by the eyesight test device; switching a first spherical lens on a first gear disk by the aid of a gear transmission technology, performing primary myopia degree test on the patient and recording a first value ofthe primary myopia degree test by the eyesight test device; switching a second spherical lens on a second gear disk by the aid of the gear transmission technology, performing secondary myopia degreetest on the patient and recording a second value of the secondary myopia degree test by the eyesight test device; calculating the first value and the second value by a computerized algorithm through adigital signal processing technology, and outputting final myopia degree results by the eyesight test device. The eyesight test method has the obvious advantages of test stability and high accuracy and precision.
Description
technical field [0001] The invention relates to the field of smart medical technology, in particular to a vision detection method and vision detection equipment. Background technique [0002] With the rapid development of social economy and the accelerated pace of life, people use their eyes excessively, resulting in a sharp decline in vision, such as myopia, hyperopia, astigmatism, etc., especially myopia. In addition to prevention and mitigation, what patients urgently need is medical attention, and optometry is essential among them. The methods of optometry mainly include subjective vision insertion method, computer refractometer, other sense retinoscopy, binocular adjustment balance, eye position examination, binocular single vision function, adjustment status, diopter status and collection function, etc. [0003] At present, the level of optometry in our domestic hospitals is uneven, and most of them are routine optometry. It is often difficult to make correct and accu...
