Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Myopia is caused by the lengthening of the eye axis and the focusing of parallel rays into the eye in front of the retina. If the length of the normal axis of the eyes of a person is more than 24mm, the myopia can be caused, the length of the normal axis of the eyes of a child is 20mm, the length of the normal axis of the eyes of an adolescent is about 23mm, the eyes have certain adjusting function, and if the eyes are excessively adjusted for a long time, the function of ciliary muscles is reduced, so that the function of convergence is reduced, and the myopia is formed. The axial line of the myopic eye is longer than that of a normal person, the crystalline lens is equivalent to a convex lens, an object is imaged on the retina through the crystalline lens of an eyeball when an object is seen, because the axial line of the myopic eye is longer, the image formed by light passing through the crystalline lens is in front of the retina, and therefore the eye is equivalent to a concave lens, and the image can be formed on the retina. The sensitization of human eyes mainly displays clear images through the distance between the cornea and the axis of the eyes, and the axis of the eyes generates myopia, so that the correct distance of the axis of the eyes is mainly controlled for preventing and controlling the myopia. And some myopia prevention's instruments that use at present only warn so that the user adjusts the distance to the user, can not fundamentally prevent, consequently the utility model provides a plastic cushion of cornea and prevention and control myopia training appearance, will be described in detail through specific embodiment next.

Example 1

A soft pad for shaping cornea is disclosed, which is shown in the front view, the top view and the bottom view of the soft pad for shaping cornea in figures 1-3, wherein the soft pad for shaping cornea is irregular in shape and is integrally in a similar convex structure, and when in use, the soft pad is matched with a training instrument and is pressed on an upper eyelid by an elastic band to shorten the focal length of an axis of an eye, thereby achieving the effect of preventing and controlling myopia.

Specifically, as shown in fig. 1, the cornea shaping soft pad includes a bottom pad 1 and a protrusion 2 extending upward from the bottom pad 1, in this embodiment, the bottom pad 1 and the protrusion 2 are an integral structure; as shown in fig. 2 and 3, the base pad 1 has an irregular shape, and one side of the base pad has an arc-shaped structure. In addition, in the present embodiment, as shown in fig. 1, the thickness of the base mat 1 is not uniform, that is, the thickness on the right side of the protrusions 2 is greater than the thickness on the left side of the protrusions 2.

In this embodiment, as shown in fig. 1 and 3, the protrusion 2 has a smooth peak-shaped structure and is hollow inside, and the base pad 1 is provided with a through hole 101 communicating with the hollow inside of the protrusion 2. The hollow structure can avoid overlarge pressure and avoid pain when being worn and used.

Specifically, in this embodiment, as shown in fig. 1 and 2, the top end of the protrusion 2 is in a circular plane shape, so as to avoid discomfort caused by pressing the tip against the eye, and the diameter of the top end of the protrusion 2 is 1.2 cm.

In this embodiment, the whole height of the plastic cushion of cornea is 2.5cm, and whole length is 4.5cm, and the size in the use can also be adjusted according to particular case, and medical silica gel is chooseed for use to the material of the plastic cushion of cornea, and makes through the processing of injection molding process.

Example 2

An anti-myopia training apparatus, as shown in fig. 4, comprises a training apparatus body 3 and the corneal shaping pad of embodiment 1, the corneal shaping pad is installed in the orbit of the training apparatus body 3, and the bulge 2 is far away from the training apparatus body 3 so that the bulge 2 can contact the upper eyelid when in use. It should be noted that the training instrument body 3 is a betz training instrument, that is, the training instrument body 3 of this embodiment is the prior art, and therefore the specific structure and the working principle of this embodiment are not described in detail again. In other embodiments, the training instrument body is not needed, the cornea shaping soft pad can be directly installed on the supporting frame, the pressure is applied through the elastic band, and the cooperation with the existing Betz training instrument is adopted to improve the prevention and control effect.

When the training instrument is used, the myopia development of children and teenagers can be controlled by wearing the training instrument for more than 1 hour every day, and by means of the prevention and control of the myopia prevention and control training instrument in the embodiment 2, as shown in fig. 5, the front central part of the cornea can be flattened, so that the focal length of the axis of the eye is shortened.

It should be noted that, for those skilled in the art, without departing from the inventive concept, several variations and modifications can be made, which are within the scope of the present invention.
