In the embodiment of the present invention, the protective cover 10 is provided with a front cover 13, and the front cover 13 is used for covering the first window 11 and the second window 12 when the vision training device 100 is not used, so as to prevent dust and the like from entering the vision training device 100.

In a specific implementation, a first control button and a second control button are provided on the vision training device 100.

After the first control key is triggered, the first lead screw sliding motor can be controlled to work, the first lead screw sliding motor drives the first separation blade 21 to move relative to the first window 11, and when the first separation blade 21 does not shield the first window 11, the vision training of left eyes can be performed. When the positions of the first blocking piece 21 and the first window 11 are in the overlapped state, the first window 11 is in the shielding state, and the vision training of the left eye cannot be performed.

After the second control key is triggered, the second lead screw sliding motor can be controlled to work, the second lead screw sliding motor drives the second separation blade 22 to move relative to the second window 12, and when the second separation blade 22 does not shield the second window 12, the vision training of the right eye can be carried out. When the positions of the second sheet 22 and the second window 12 are in the overlapped state, the second window 12 is in the shielding state, and the vision training of the right eye cannot be performed.

It should be noted that, in the embodiments of the present invention, "first", "second", etc. in the first pressing member, the second pressing member, the first blocking piece, the second blocking piece, the first lifting mechanism, and the second lifting mechanism are not used to indicate the order of the corresponding devices, or a certain device, and are merely for convenience of description.
