The clamping holes 192 or the clamping grooves 193 are in one-to-one correspondence with the clamping buckles 182 and are matched with each other, and the clamping buckles 182 are inserted into the corresponding clamping holes 192 or the clamping grooves 193 to connect and fix the upper cover 18 and the shell main body 19.

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

When the first transmission assembly 21 is controlled to drive the two near vision lenses 2 to extend out of the casing 1, and the second transmission assembly 31 is controlled to drive the two far vision lenses 3 to be positioned in the casing 1, so that only the two near vision 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.

The first preset time and the second preset time are adjustable.

The detailed working process is as follows: the battery 4 supplies power to the main control circuit board 5, and the main control circuit board 5 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) move to the vision area for a first preset time, the main control circuit board 5 controls the rotation axis 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 61, the first limit switch 61 is turned off and transmits a signal to the limit switch circuit board 6, and the limit switch circuit board 6 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 5 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, so as to move to the vision area, and the user can do far-viewing (or near-viewing) 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 5 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 61, the first limit switch 61 is closed and transmits a signal to the limit switch circuit board 6, and the limit switch circuit board 6 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.

Optionally, the first preset time and the second preset time are increased by the second key 7, and the first preset time and the second preset time are reduced by the third key 8.

According to the eye training instrument provided by the invention, the first transmission component 21 is arranged to drive the myopia lens 2 to reciprocate, the second transmission component 31 is arranged to drive the hyperopia lens 3 to reciprocate, so that the eye training instrument is small in transverse occupied space and convenient to use.
