After the examined person mounts the frame body 100 on the face through the hanging lugs 400, the transparent piece 500 can be directly placed in front of the eyes in a mode of wearing glasses, and then the transparent piece 500 can be automatically and continuously positioned without continuously holding the examined person. Then, the person to be tested can adjust the relative distance between the two transparent members 500 through the distance adjusting structure 800, so as to ensure that the two transparent portions 550 can be adapted to the interpupillary distance of the person to be tested. Finally, by operating the shielding structure 600, the shielding effect of the light transmitting portion 550 can be achieved or canceled, thereby completing the shielding operation of the single eye during the vision inspection and test. After the frame body 100 is worn by the hanging lugs 400, the shielding effect on eyes can be directly and effectively achieved, and the interpupillary distances of different detected personnel can be adaptively adjusted through the distance adjusting structure 800, so that vision detection operation can be rapidly and effectively carried out, and the operation efficiency is improved.
It is envisioned that the light transmitting portion 550 may be a hollowed-out portion or may transmit light through a lens. The specific embodiments can be adjusted according to actual needs, and are not limited herein.
In some embodiments, referring to fig. 1, the distance adjusting structure 800 includes an adjusting beam 200 mounted to the frame 100, and two light transmitting members 500 are slidably disposed on the adjusting beam 200; the adjustment beam 200 is provided with a first adjustment knob 350, and the first adjustment knob 350 can push the light-transmitting member 500 and drive it to slide relative to the adjustment beam 200.
