Detailed Description

In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the following description of the present invention will refer to the accompanying drawings and illustrate embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1-4, a training device for improving eyesight includes a frame 2 and two lenses 1, the lenses 1 are fixed on the frame 2 through a connecting shaft 11, that is, the two lenses 1 are respectively hinged on the frame 2, so that the lenses 1 can rotate relative to the frame 2, or a structure without hinging can be adopted, the lenses 1 are fixed on the frame 2, one surface of the inner aperture 121 of the through hole 12 faces the frame 2, and the small aperture of the through hole faces the direction of eyes, so as to facilitate the wearing of the user. In specific implementation, more than three through holes are preferably adopted, so that light rays only directly pass through the through holes 12 and can directly reach eyeballs when a user wears the glasses, and the problems of scattering and diffraction existing in the original small-hole lenses are effectively solved; and the problem of light interference is solved, and a user can see clearly and cleanly after wearing the glasses.

In this embodiment, in order to facilitate the use, it corresponds 1 position of lens and is provided with light screen 3 on spectacle frame 2, and light screen 3 can arrange lens 1 in front for through rotatory light screen 3, with the light screen parallel in the 1 outside of lens, can shelter from light, be equivalent to monocular eye-shade, thereby can cooperate monocular exercise, horizontal shading, reduce aperture interference light, improve the effect of training glasses. In a specific implementation, the light shielding plate 3 is an opaque lens.

In this embodiment, in order to ensure that the light passes through the through hole 12 and prevent the light from being too transmitted, the paraboloid of the through hole satisfies the following formula: y is ² And the number of the light rays is just 0.75, so that the through-hole imaging effect is not influenced.

In this embodiment, a connecting plate 21 is disposed on the spectacle frame 2 corresponding to the lens 1, the connecting plate 21 has a rotating shaft 22, one end of the rotating shaft 22 is fixedly connected to one corner of the light shielding plate 3, and the rotating shaft rotates to realize that the light shielding plate 3 is parallel or perpendicular to the lens 1, thereby achieving the effect of adjusting the light transmission.

In this embodiment, in order to achieve better correction effect, the inner aperture 121 of the through hole 12 is 0.8-1.2mm, the outer aperture 122 of the through hole 12 is 4.0-4.4mm, and the diameter of the pupil of the human eye is preferably 1mm for the inner aperture 121 of the through hole 12 and 4.2mm for the outer aperture 122 of the through hole 12, so as to ensure the effect of light passing through.

In this embodiment, the lens 1 is preferably provided with more than ten through holes 12, the through holes 12 are distributed in rows and columns to correspond to the eyes of the user, and the adjacent through holes 12 are distributed equidistantly, or of course, one through hole may be used as a center and distributed circumferentially around the center through hole, and the lens can be used, but the moving range of the eyes is not enough.
