The user is through two near-sighted lens 2 does the training of seeing near, after the training of seeing near department is accomplished, first preset time back promptly, controls two again near-sighted lens 2 and two far-sighted lens 3 position exchanges, and the user is through two far-sighted lens 3 does the training of seeing far, after the training of seeing far is accomplished, second preset time back promptly, two far-sighted lens 3 and two of control again near-sighted lens 31 position exchanges, so looks near department and the training of seeing far in turn to train the binocular.

The control in the foregoing is to perform the near-sight training first and then the far-sight training, and in addition, the far-sight training may be performed first and then the near-sight training may be performed.

In addition, in training the eyes, the user may have a need to train a single eye. Then, at this time, the third transmission assembly 41 can be controlled to drive the first shielding plate 4 to extend out of the housing 1, and the fourth transmission assembly 43 can be controlled to drive the second shielding plate 42 to be located in the housing 1, so that only the first shielding plate is located in the visual area, and the first shielding plate shields one of the eyes (for example, the left eye), and thus trains the other non-shielded single eye. After the monocular training is completed, that is, after a third preset time, the third transmission assembly 41 is controlled to drive the first shielding piece 4 to retract into the housing 1.

The fourth transmission assembly 43 of the second shielding sheet mechanism can also be controlled to drive the second shielding sheet 42 to extend out of the housing 1, and the third transmission assembly is controlled to drive the first shielding sheet to be located in the housing 1, so that only the second shielding sheet 42 is located in the visual region to shield another eye (for example, the right eye), thereby realizing training on another single eye without shielding.

The rotation shaft of the first motor 214 (or the second motor) drives the first screw 212 (or the second screw) to rotate in a second rotation direction, so as to drive the first slider 213 (or the second slider) to move in a second movement direction, which is opposite to the first movement direction, and further drive the two near vision lenses 2 (or the two far vision lenses 3) to move in the second movement direction. Each myopic lens 2 (or each hyperopic lens 3) passes through the corresponding lens outlet 13 and retracts into the housing 1, thereby moving out of the optical zone. The first frame 22 (or the second frame 32) touches and presses the corresponding first limit switch 531, the first limit switch 531 is turned off and transmits a signal to the limit switch circuit board 53, and the limit switch circuit board 53 further controls the first motor 214 (or the second motor) to stop working, so that the two near vision lenses 2 (or the two far vision lenses 3) are not driven to move.

The main control circuit board 52 controls the second motor (or the first motor 214) to work, so as to drive the two far vision lenses 3 (or the two near vision lenses 2) to extend out of the housing 1, so as to move to the vision area, and a user can do a training of seeing far (or seeing near) through the two far vision lenses 3 (or the two near vision lenses 2).

After the two far vision lenses 3 (or the two near vision lenses 2) move to the visual area for a second preset time, the main control circuit board 52 controls the rotation shaft of the second motor (or the first motor 214) to change the rotation direction, so as to drive the two far vision lenses 3 (or the two near vision lenses 2) to retract into the housing 1, so as to move out of the visual area, the second frame 32 (or the first frame 22) presses the corresponding first limit switch 531, the first limit switch 531 is turned off and transmits a signal to the limit switch circuit board 53, and the limit switch circuit board 53 further controls the second motor (or the first motor 214) to stop working, so as not to drive the two far vision lenses 3 (or the two near vision lenses 2) to move.
