The eye training device is described below in connection with specific use:

When two eyes need to be trained, the first transmission assembly 21 can be controlled to drive the two near-sighted lenses 2 to extend out of the shell 1, and the second transmission assembly 31 can be controlled to drive the two far-sighted lenses 3 to be positioned in the shell 1, so that only two near-sighted lenses 2 are positioned in the vision area. The user does near training through the two near vision lenses 2, after near vision training is completed, namely, after a first preset time, the positions of the two near vision lenses 2 and the positions of the two far vision lenses 3 are controlled to be interchanged, the user does far vision training through the two far vision lenses 3, after far vision training is completed, namely, after a second preset time, the positions of the two far vision lenses 3 and the two near vision lenses 31 are controlled to be interchanged, so that near vision training and far vision training are alternately performed, and eyes are trained.

The control is that the near training is performed first and then the far training is performed, and in addition, the far training can be performed first and then the near training can be performed.

Furthermore, the user may have a need to train a single eye while training the eye. Then, at this time, the third transmission assembly 41 may be controlled to drive the first shielding plate 4 to extend out of the housing 1, and the fourth transmission assembly 43 may 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 vision area, and the first shielding plate shields one eye (for example, the left eye) so as to train the other single eye without shielding. After the monocular training is completed, i.e. after a third preset time, the third transmission assembly 41 is controlled to drive the first shielding plate 4 to retract into the housing 1.

The fourth transmission component 43 of the second shielding sheet mechanism may be controlled to drive the second shielding sheet 42 to extend out of the casing 1, and the third transmission component may be controlled to drive the first shielding sheet to be located in the casing 1, so that only the second shielding sheet 42 is located in the vision area, and the other eye (for example, the right eye) is shielded, so as to implement training on the other single eye without shielding. After the monocular training is completed, i.e. after a fourth preset time, the fourth transmission assembly 43 is controlled to drive the second shielding plate 42 to retract into the housing 1.

The first preset time, the second preset time, the third preset time and the fourth preset time are all adjustable.

The detailed working process is as follows: the battery 51 supplies power to the main control circuit board 52, and the main control circuit board 52 operates and controls the first motor 214 (or the second motor) to operate and controls the rotation axis of the first motor 214 (or the second motor) to rotate in a first rotation direction. 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 first rotation direction, so as to drive the first slider 213 (or the second slider) to move in a first movement direction. The first slider 213 (or the second slider) drives the two near vision lenses 2 (or the two far vision lenses 3) to move towards the first movement direction, each near vision lens 2 (or each far vision lens 3) passes through the corresponding lens outlet 13 and protrudes out of the shell 1, so that the near vision area is moved, and a user can do near (or far) watching training through the two near vision lenses 2 (or the two far vision lenses 3).

After the two near vision lenses 2 (or the two far vision lenses 3) are moved to the vision area for a first preset time, the main control circuit board 52 controls the rotation shaft of the first motor 214 (or the second motor) to rotate in a second rotation direction opposite to the first rotation direction. 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, and further drive the two near vision lenses 2 (or the two far vision lenses 3) to move in the second movement direction, wherein the second movement direction is opposite to the first movement direction. Each near vision lens 2 (or each far vision lens 3) is retracted into the housing 1 through the corresponding lens outlet 13, thereby moving out of the vision zone. The first frame 22 (or the second frame 32) touches 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 as not to drive the two near-sighted lenses 2 (or the two far-sighted lenses 3) to move.

The main control circuit board 52 further controls the second motor (or the first motor 214) to operate, so as to drive the two hyperopic lenses 3 (or the two myopia lenses 2) to extend out of the casing 1, thereby moving to the vision area, and the user can do far (or near) watching training through the two hyperopic lenses 3 (or the two myopia lenses 2).

After the two distance lenses 3 (or the two near lenses 2) move to the vision 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 distance lenses 3 (or the two near lenses 2) to retract into the shell 1, so as to move out of the vision area, the second lens frame 32 (or the first lens frame 22) touches the corresponding first limit switch 531, the first limit switch 531 is closed 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 that the two distance lenses 3 (or the two near lenses 2) are not driven to move.

The two myopia lenses 2 and the two hyperopia lenses 3 are alternately moved to the vision area in this way, and the eyes are alternately trained to look near and far, so that the eyes are trained, the lenses and ciliary muscles of the eyeballs are trained, and myopia is prevented or vision is corrected. Because the eye training instrument alternately moves the near vision lens 2 and the far vision lens 3 to the vision area, the near vision training and the far vision training are respectively carried out on eyes, rather than the near vision training and the far vision training are carried out on the eyes in a lens overlapping mode, the lens degree setting is simple, the lens degree setting is more flexible and convenient, and the harm caused by the lens degree error problem caused by lens overlapping is avoided.

Alternatively, the first preset time and the second preset time are increased by short pressing the second key 7, and the first preset time and the second preset time are decreased by short pressing the third key 8.

The main control circuit board 52 controls the third motor to work, so that the first shielding sheet 4 is driven to extend out of the shell 1, so that the first shielding sheet 4 moves to the vision area, one eye is shielded by the first shielding sheet 4, and the other eye is trained to look near and look far alternately, so that the single eye is trained.

After the first shielding plate 4 moves to the vision area for a third preset time, the main control circuit board 52 controls the rotating shaft of the third motor to change the rotating direction, so as to drive the first shielding plate 4 to retract into the housing 1, so that the first shielding plate 4 moves out of the vision area, the first connecting frame 411 of the first shielding plate 4 contacts and presses the corresponding second limit switch 532, the second limit switch 532 is closed and transmits a signal to the limit switch circuit board 53, and the limit switch circuit board 53 further controls the corresponding third motor to stop working, so that the first shielding plate 4 is not driven to move.

Similarly, the second occlusion sheet 42 may be controlled to occlude another eye, thereby training another single eye.

Optionally, the first shielding sheet 4 is controlled to extend out of the housing 1 by long pressing the second key 7, and the second shielding sheet 42 is controlled to extend out of the housing 1 by long pressing the third key 8.

The eye training device provided by the invention is provided with the myopia lens mechanism and the hyperopia lens mechanism, and the first transmission component 21 drives the myopia lens 2 to reciprocate, so that the myopia lens 2 moves to or from the vision area. When the near vision lens 2 moves to the vision area, the user looks near through the near vision lens 2. The second transmission assembly 31 reciprocates the distance vision lens 3 so that the distance vision lens 3 moves to or from the vision area. When the distance vision lens 3 moves to the vision area, the user looks far through the distance vision lens 3. The eyes are trained by alternately looking near and far. The first shielding sheet mechanism is further arranged, the third transmission assembly 41 drives the first shielding sheet 4 to reciprocate, so that the first shielding sheet 4 moves to or from the vision area to shield eyes which do not need to be trained, the eyes which need to be trained are independently trained, the function is flexible, and the requirement on monocular training can be met.
