At present, learning desks are very common among young people. How to let children use the learning desks to check their eyesight regularly, so that they can check themselves without the busyness of their parents. This product is still blank at present; When going to the hospital for inspection, the distance between the equipment and the subject is fixed. When the inspection site cannot provide a space that meets the fixed distance, vision inspection cannot be performed. In addition, the hospital wastes too much time from registration to inspection. inconvenient

Embodiment 1
[0038] refer to figure 1 , a method for visual acuity detection based on a study table, including setting an optotype through a study table, the subject sitting at a designated position, the optotype information seen by the subject through voice feedback, the processing unit obtaining the feedback information, and the feedback information to determine the subject's visual acuity value.
[0039] Usually, the optotype is in the shape of the word "E", and the optotype information refers to the opening orientation information of "E". Up, down, left, right, unclear, up, down, left, right, up, down, left, right, etc., a series of words indicating the opening direction of "E".
[0040] A distance measuring sensor, a camera, a storage unit, a display unit, a sound unit and a processing unit are installed on the study table, and the processing unit is respectively connected with the distance measuring sensor, the camera, the storage unit, the display unit and the sound unit. For meas...
Embodiment 2
[0057] refer to Figure 4 , the study desk 3 is provided with a bookshelf, the bookshelf is provided with a functional book holder 2, the functional book holder 2 is provided with a tablet computer 1, and the tablet computer 1 is installed with a camera, a speaker, a microphone, a ranging sensor, a storage unit, a display and a processing unit, which is respectively connected with a camera, a sound box, a microphone, a ranging sensor, a storage unit, and a display. The ranging sensor is set to the front of the tablet.
[0058] The distance measuring sensor is used to measure the distance from the subject to the display, the camera is used to detect whether the subject is directly opposite the display unit, the storage unit is used to store the optotype set, and the optotype set includes optotypes of different models.

Abstract
The invention discloses a learning desk-based vision detection method, which comprises the following steps of: setting a sighting mark through a learning desk, sitting a testee at a specified position, feeding back sighting mark information seen by the testee through voice, acquiring feedback information by a processing unit, and determining a vision value of the testee through the feedback information. A distance measuring sensor, a camera, a storage unit, a display unit, a sound unit and a processing unit are installed on the learning table, the processing unit is connected with the distance measuring sensor, the camera, the storage unit, the display unit and the sound unit, and the distance measuring sensor is used for measuring the distance between a testee and the display unit. The camera is used for detecting whether a testee is located right opposite to the display unit, and the storage unit is used for storing a sighting mark set. By arranging the sighting marks on the learning table, a self-testee can complete vision detection at home by one person, time is saved, meanwhile, by drawing the vision change curve graph, the vision change condition can be known, and myopia deepening can be better prevented.
Description
technical field [0001] The invention relates to the application of children's health detection technology in the field of children's products, in particular to a vision detection method based on a study table. Background technique [0002] Myopia is a progressive disease, and prevention and protection are very important. In recent years, the detection rate of poor vision among young people in my country has remained high, and the incidence of poor vision among students has been increasing year by year. Myopia has become an important problem affecting the health of children in my country. For this reason, there is a need for a suitable vision tester to conduct regular inspections of people's eyesight. At the same time, there are tens of millions of eye disease patients every year, eager to know the recovery of their vision and the follow-up development trend. At present, study desks are widely used among teenagers. How to let children use study desks to study, they can also c...
