a multi-functional vision tester, comprising: the visual inspection box is provided with a display screen for displaying visual targets, a paper visual chart or a lamp box and a plurality of cameras for measuring the distance from human eyes to the display screen; the vision examination box is arranged on the transverse adjusting mechanism and used for adjusting the position of the vision examination box to be right in front of the glasses of the patient, so that the vision examination box is suitable for patients with different heights; the host is used for controlling the type and the size of the sighting target displayed by the display screen and adjusting the brightness and the gray scale of the display screen, so that various vision detection items can be realized, various paper visual charts or lamp boxes are prevented from being replaced, the operation steps are reduced, and the test results of the patient are collected, analyzed and stored; the remote controller is connected with the host, and the patient selects and responds to the target through the remote controller, so that the automatic storage of the test result is realized.

As the utility model discloses a another kind of preferred scheme, the host computer still links to each other with the camera, and the people's eye that records through collecting the camera is to display screen distance signal, calculates the size of adjusting the sighting mark on the display screen, reduces because the error that the distance difference between people's eye and the visual chart brought.

As the utility model discloses a another kind of preferred scheme, height adjusting mechanism and horizontal adjustment mechanism are motor control to link to each other with the host computer, the position of human eye to display screen distance signal, adjustment visual inspection case that the host computer records through collecting the camera.

As another preferable aspect of the present invention, the visual acuity test box is further provided with an "x" shaped signal lamp and a "hook" shaped signal lamp for feeding back the correctness of the selection and the response to the patient in real time.

As another preferred scheme of the utility model, the vision inspection box still sets up the audio player for interact with the patient.

As another preferred scheme of the utility model, be provided with a plurality of selection buttons and function button on the remote controller, be connected through wireless mode with the host computer for to the sighting mark on the display screen select, answer, and with the switching between the different functions.

As another preferred scheme of the utility model, the support bottom is provided with the gyro wheel, makes things convenient for the removal of support to and carry out the coarse adjustment to the position of visual examination case.

Compared with the prior art, the utility model provides a multi-functional visual acuity tester has following gain effect:

the multifunctional visual acuity tester can automatically adjust the height and the transverse position of the display screen, reduce errors caused by different positions by measuring the distance from human eyes to the display screen, and is suitable for patients with various heights; various visual acuity test charts are displayed through the display screen, so that various paper visual acuity test charts or lamp boxes are prevented from being replaced, and operation steps are reduced; the patient selects and confirms the sighting target through the remote controller, and the result is automatic to accomplish the record to can obtain real-time feedback, convenient to use and degree of automation are high.
