[0002] During the vision test, due to the different usage scenarios of the test subjects, some users need to wear polarized glasses. Polarized glasses can dissipate the reflected light from strong outdoor sunlight to prevent it from damaging the eyes, thereby protecting the user's eyes.
[0003] Currently, most polarized vision tests require the test subject to wear different polarized glasses to view a polarized test card, so that the test subject can choose the polarized lenses that suit him or her. Various polarized lenses are generally placed in drawers or other storage boxes. However, when changing different polarized lenses, this method requires staff to help the test subject find and replace the lenses. When putting the lenses back, they also need to check whether the lenses correspond to the positions they were placed in, which is quite troublesome.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

During the plugging process, the card rod 405 is squeezed by the installation rod 303, so that the card rod 405 pushes the limit plate 404 to compress the spring 403. At this time, the card rod 405 retracts into the slide groove 402 until the insertion rod 401 is fully inserted into place, the card rod 405 is aligned with the card hole 304, and the spring 403 pushes the limit plate 404 and the card rod 405 to reset, so that the card rod 405 is plugged into the card hole 304, thereby limiting and fixing the insertion rod 401.

[0041] In one embodiment, for the thumbwheel 201 , an anti-slip protrusion 8 is fixedly connected to the outer surface of the thumbwheel 201 .
[0042] When rotating the thumbwheel 201 , the operator's hand contacts the anti-skid protrusion 8 on the thumbwheel 201 , which increases the friction force and avoids slipping.
[0043] In summary, with the aid of the above-mentioned technical solution of the present invention, the person being tested sits in front of the pedestal 1 and views the polarization test card 6 through the polarizer 5 on the pedestal 1.

The specific steps are: find the mounting rod 303 on the rotating seat 302, push the card rod 405 separates it from the locking hole 304 on the mounting rod 303, thereby releasing the limit fixation between the insertion rod 401 and the mounting rod 303. At this time, the insertion rod 401 and the polarizer 5 can be removed from the mounting rod 303, and then the new polarizer 5 and the insertion rod 401 can be plugged into the mounting rod 303. During the plugging process, the locking rod 405 is squeezed by the mounting rod 303, so that the locking rod 405 pushes the limit plate 404 to compress the spring 403. At this time, the locking rod 405 retracts into the slide groove 402 until the insertion rod 401 is fully plugged into place, the locking rod 405 is aligned with the locking hole 304, and the spring 403 pushes the limit plate 404 and the locking rod 405 to reset, so that the locking rod 405 is plugged into the locking hole 304, thereby limiting and fixing the insertion rod 401 and the polarizer 5 to prevent unnecessary movement of the polarizer 5.

Multiple sets of polarizers 5 are arranged in an orderly manner to avoid confusion.
