Commonly used visual function tests include visual psychophysical examinations (such as visual acuity, visual field, color vision, dark adaptation, stereoscopic vision, contrast sensitivity) and visual electrophysiological examinations. Examinations of visual acuity, visual field, etc. require the examiner to use appropriate equipment to conduct the examination and the patient to make a judgment through psychological activities, so it is called a visual psychophysical examination.

Then, the height of the forehead rest 5 is adjusted. The index fingers of both hands are respectively inserted into the pull ring 63 upward and pulled outward, so that the second tooth block 61 is disengaged from the second tooth 312. At the same time, the palms of the hands hold the two sides of the forehead rest 5 to move the forehead rest 5 upward or downward so that its height is just at the forehead. Then, the pull ring 63 is released to reset it under the action of the second reset spring 64, so that the second tooth block 61 is re-engaged with the second tooth 312, and the height of the forehead rest 5 is fixed.

In order to prevent the disinfectant in the liquid storage capsule 8 from moving downward due to gravity, a valve one-way valve can be provided in the liquid storage capsule 8 not close to the internal threaded ring, and the disinfectant can be squeezed out only when external force is applied by hand, thereby avoiding waste of disinfectant.

[0064] The working principle of the present invention is as follows: the patient first places his chin on the arc-shaped groove 410 in the middle of the chin rest 4. The first compression spring 45 has a certain supporting force. The patient adjusts the height of the chin rest 4 according to his own height and fixes the height of the chin rest 4 by means of the handle 444; then the index fingers of both hands are respectively inserted upward into the pull ring 63 and pulled outward to make the height of the forehead rest 5 meet his own needs, and then the pull ring 63 is released; an optical lens 21 is arranged on the front side of the inspection device body 2, and a display screen 22 and a control panel 23 are arranged on the rear side. The doctor controls the position of the inspection device body 2 through the control panel 23 so that the optical lens 21 is aligned with the patient's eyes, and then controls the inspection device body 2 for inspection by operating the control panel 23. The processor inside the inspection device body 2 moves the optical lens 21 to the front side of the inspection device body 2. The optical information collected by the display 21 is processed and displayed on the display screen 22 for the doctor to view. The doctor can also transmit the information on the display screen 22 to the Internet through the control panel 3. The Internet analyzes the data and searches with the network database, and transmits the patient's condition and case to the display screen 22 through the control panel 3. The doctor can make an accurate diagnosis of the patient through the condition displayed on the display screen 22 and his own medical knowledge; after the patient examination is completed, the patient or the doctor can pinch the liquid storage capsule 8 with the hand to soak the disinfectant cotton 757 with the disinfectant, and then rotate the worm 761 with the hand to disinfect the surfaces of the chin rest 4 and the forehead rest 5 that are in contact with the human body, and then rotate the worm 761 in the opposite direction to restore the disinfectant cotton 757 to its original position (that is, on both sides of the chin rest 4 and the forehead rest 5).

[0065] The present invention is further described above in conjunction with the embodiments, but the present invention is not limited to the above-mentioned implementation modes, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
