Embodiment 1

[0045] In order to facilitate the understanding of the entire technical solution, the term diopter that appears in this article is explained. The diopter is the deflection of the propagation direction of the light when the light is injected from one object into another material with different optical density. This phenomenon is called It is a refractive phenomenon, and the unit that expresses the size (refractive power) of this refractive phenomenon is the diopter (abbreviated as "D"). 1D is medically prescribed as 100 degrees.

[0046] Please refer to figure 1 with figure 2 , figure 1 It is a structural schematic diagram of an adjustable spectacles for refractive correction of the present invention. figure 2It is a disassembled structure schematic diagram of adjustable glasses for refractive correction of the present invention. The adjustable glasses include a glasses body 1, an auxiliary corrective spectacle lens 2, a first corrective spectacle lens 3, and a second cor...

Embodiment 2

[0056] Please refer to Figure 7 , Figure 7 It is a structural schematic diagram of another adjustable spectacles for refractive correction of the present invention. This implementation is basically the same as that of Example 1, the difference is that in this embodiment, the auxiliary corrective diaphragm 5, the first corrective diaphragm 6, and the second corrective diaphragm 7 are used instead of the auxiliary corrective spectacle lens 2 in Embodiment 1. , the first correction glasses 3, the second correction glasses 4; the auxiliary correction diaphragm 5 is pasted on the inner surface of the glasses body 1; the first correction diaphragm 6 and the second correction diaphragm 7 are pasted on the glasses body alone The outer surface of 1; the diopter of the auxiliary correcting film 5 is +1D to -1D; the diopter of the first correcting film 5 is -2D; the diopter of the second correcting film 5 is- 4D; when in use, the corresponding diaphragm can be attached to the glasses...

Abstract

The invention relates to a pair of adjustable glasses for diopter correction. The adjustable glasses comprise a glasses body, auxiliary correction eyeglasses, a pair of first correction glasses and a pair of second correction glasses, wherein the auxiliary correction eyeglasses are connected with the inner surface of the glasses body and can be moved left and right by rotating screw rods, and the degree of the glasses can be changed by changing the positions of the auxiliary correction eyeglasses; the first correction glasses and the second correction glasses are connected with the outer surface of the glasses body in a detachable way; magnet pieces are installed in an eyeglasses frame; the eyeglass diopters of the glasses body are -1D; the diopters of the auxiliary correction eyeglasses are +1D to -1D; the eyeglass diopters of the first correction glasses are -2D; the diopters of the second correction glasses are -4D. The adjustable glasses have the advantages that a proper degree can be adjusted according to different dioptric states of every day, so that the problem of myopia caused by ametropia of distant vision can be effectively solved; the adjustable glasses are especially used for helping child and adolescent myopia patients to correct vision, thus having wide application prospect.

Description

technical field [0001] The invention relates to the technical field of spectacles, in particular to adjustable spectacles for refractive correction. Background technique [0002] In recent years, based on genetics and changes in modern lifestyles, myopia has become an eye disease with a very high incidence, especially among children and adolescents. According to relevant reports, the myopia rate of children and adolescents has reached 80%. Because the eyeballs of children and adolescents are in the growth and development stage, if they are not corrected in time, the excessive development of the retina will lead to an increasing degree of myopia. Therefore, refractive correction is of great significance. [0003] Refractive correction is to adjust and move the clear image that cannot be accurately presented on the retina to a specific position of the retina through some means, so that people with refractive errors can obtain clear vision. The correction of myopia in the pr...
