Description

Myopia prevention and control glasses

Technical Field

The utility model relates to the technical field of myopia prevention, in particular to myopia prevention and control glasses.

Background

The fog vision method is a myopia prevention method, and the principle is that the eye to be tested is in an artificial myopia state, namely, an object image is gathered in front of retina. The fog vision method can reduce burden of looking near by the convex lens, thereby preventing myopia. According to the principle, the current products for preventing and treating pseudomyopia by optical physical therapy are mainly classified into far-fog vision products and near-fog vision products, but cannot achieve the effects of forcing ciliary muscle to relax, replacing ciliary muscle to work and avoiding internal rectus muscle to work at the same time, so that pseudomyopia cannot be prevented and treated most effectively, and deepening of true myopia cannot be prevented. There is thus currently a lack of a product that combines far and near fog vision.

Detailed Description

Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

As shown in fig. 1, the embodiment provides a pair of myopia prevention and control glasses, which comprises a glasses frame 1, wherein two glasses frames of the glasses frame 1 are respectively connected with a lens 4, and the structures of the two lenses 4 are identical. The left and right sides of the glasses frame 1 are respectively provided with a glasses leg 3, the middle of the glasses frame 1 is provided with two nose pads 2, and the shape of the lens 4 is circular or elliptical, which is not limited in this embodiment. The specific structure of the lens 4 is as follows:

as shown in fig. 2 to 4, the upper portion of each lens 4 is an upper refractive zone 5 and the lower portion is a lower refractive zone 6, and the front portion of the lower refractive zone 6 is a refractive zone 7 for changing divergent light into parallel light, or the rear portion of the lower refractive zone 6 may be a refractive zone 7, and the front portion is a refractive zone 7 in this embodiment. However, the upper Qu Guangou, lower refractive zone 6 and refractive zone 7 are manufactured integrally using a manufacturing process. Specifically, the combination of the upper Qu Guangou, lower refractive zone 6 and refractive zone 7 can adopt a process of pressure-gathering, adhesion and fusion, and the process is the prior art, so that the implementation cost is low, and the production and manufacturing cost is reduced. The upper Qu Guangou and lower refractive zones 6 are convex lenses, and the refractive index of the upper refractive zone 5 is +1.00d to +4.00d, and the refractive index of the lower refractive zone 6 is +0.50d to +3.00d. The upper Qu Guangou and lower refractive zone 6 portions should have the same curvature but different densities to achieve different refractive indices. The material aspect adopts optical glass and resin.

As shown in fig. 5 and 6, in order to obtain natural viewing habits, the upper refractive zone 5 is circular in shape, and the area of the upper refractive zone 5 occupies 1/4 to 1/2 of the area of the lens 4. The upper Qu Guangou is preferably circular in shape and the eye is directed through the center of the upper refractive zone 5 in plan view. The whole lens 4 is a hyperboloid spherical lens. The upper Qu Guangou and lower refractive zones 6 can be formed with different refractive powers using different densities, or can be formed with different spherical curvatures. In addition, the cross-sectional shape of the lens 4 is an arcuate lens 4. The arcuate lens sheet 4 is designed to equalize the refractive power of the center and the periphery of the lens sheet 4, thereby avoiding the problem of deformation of the imaging pattern when viewing objects around the lens sheet 4, the arcuate lens sheet 4 being also called a peripheral vision lens sheet 4.

In this embodiment, the refractive region 7 functions as a triangular lens, and the prism degree is 1.5 to 8 Δ. Three sides of the refraction area 7 face the nose pad 2, the front of the lens 4 and the lower refraction area 6 respectively, wherein the side face facing the nose pad 2 is a bottom surface 8, and the lower refraction area 6 and the refraction area 7 can change the angle of light entering eyes within five meters to replace the vergence effect of eyes, thereby replacing the contraction and fatigue of internal rectus muscles. The second incentive for the extension of the eye axis is eliminated. Because it has been studied that the contraction of the internal rectus muscle can exert a pulling force on the eye, forcing the axis of the eye to lengthen.

The lens 4 in this embodiment is divided into an upper refractive zone 5 and a lower refractive zone 6, the upper refractive zone 5 is capable of converting parallel light beyond 5 meters into converging light, a myopic patient will see less clearly far away, and the accommodation mechanism of the brain will instruct the ciliary muscle to relax for clarity, the curvature of the lens will be reduced, and the lens will be seen more clearly when the lens is removed than when the lens is removed from the naked eye. The lower refractive zone 6 of the lens 4 is further compounded with a refractive zone 7, the refractive zone 7 having a prism of 1.5-8 delta. Diopter and prism replace the regulation and collection needed by near vision of human eyes, and the near object light into far object parallel light can be changed into near vision, so that obvious effect of preventing and curing myopia can be achieved, and abnormal functions of regulation and collection of human eyes can be corrected.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description.
