The pinhole member 700 is provided in the first opening 442 formed on the front surface of the shaft support part 440. The pinhole member 700 serves as a pinhole in a circular or oval plate shape having at least one pinhole. The pinhole is formed in the size of 0.5mm to 3mm. When the pinhole member 700 is provided in the first opening 442 of the shaft support part 400, a pair when the gap between the pair of

lens units

410, 420 is adjusted by the gap adjusting part 450. The spacing between the pinhole member 700 will also be adjusted at the same time.

The pinhole member 700 visualizes different eyesight for each user. When viewing an object through the pinhole of the pinhole member 700, the astigmatism of the user's eyesight may be removed, and myopia and hyperopia may be partially improved. Thus, the pinhole member 700 makes the user's vision near to normal eye.

First, the user wears the vision improving device 10 and then adjusts the dial 458 to adjust the distance between the

lens units

410 and 420 according to the distance between the eyes. When the distance between the

lens units

410 and 420 is adjusted according to the distance between the eyes of the user, one of the lenses 416 and the pinhole member 700 among a plurality of lenses having different diopter values in the user's eye direction 2 is different. ), Any one pinhole is located. The user recognizes the object 1 through one of the pinholes of the lens 416 and the pinhole 701 of the pinhole member 700. The pinhole member 700 may correct eyesight of different users for each user in order to improve the training effect of the vision improving device 10. That is, the astigmatism of the user's eyesight is removed and the myopia or hyperopia is improved to make the user's eyesight as close as possible to normal eyesight. Here, the normal eye refers to a state in which astigmatism and myopia or hyperopia are removed from the user's eyesight.

First, a user recognizes an object through a reference lens. The reference lens may be a lens having a diopter of zero.

Thereafter, after the set reference time passes, the

lens units

410 and 420 rotate by the set angle to change the reference lens to another set lens. In this case, the diopter value of the lens to be changed may be -1. Since the user must recognize the object through a lens whose diopter value is changed, the capsular root of the user contracts or relaxes to clearly see the object. After the set reference time elapses after changing to a lens having a diopter value of −1, the lens units 410 and 20 change the lens having a diopter value of −1 to a lens having another diopter value. The diopter value of the lens to be changed may be +1. Since the user needs to recognize the object through the lens whose diopter value is changed again, the capsular root of the user relaxes or contracts again to see the object clearly. Here, the diopter value of the reference lens to be set, the diopter value to be changed, and the reference time for changing the lens may be changed to other values or times according to the improvement of the vision according to the user's vision and training.

In the vision improving apparatus according to the exemplary embodiment of the present invention, the capsular control muscle of the user may be repeatedly relaxed and contracted through repetition of the set operation as described above, thereby strengthening the muscular strength. Thus, the eyesight of the user can be improved. In addition, since the eyesight of the user is corrected by using the pinhole of the pinhole member 700, the vision improving device 10 according to the present invention can be used universally by many users with different vision. In addition, the user's ease of use is improved because a separate custom lens for each user with different eyesight is not required.
