Abstract

The utility model discloses myopia prevention spectacles for adolescents, comprising a spectacle frame (1) and large myopia spectacle lens (2) which are arranged on the spectacle frame (1). Convex spherical lens (3) integrated or spliced into a whole are arranged at the outer side of the lower part of the large myopia spectacle lens (2); arc-shaped triangular prism (5) integrated or spliced into a whole are arranged at the inner side of the large myopia spectacle lens (2) corresponding to the convex spherical lens (3); the base of the arc-shaped triangular prism (5) faces the nose; the convex spherical lens (3), the large myopia spectacle lens (2) and the arc-shaped triangular prism (5) compose a prism-typed combination lens. Adopting the structure above mentioned, the utility model avoids the disadvantages of the double-light spectacles, the progressive multi-focal lens and the prism-typed combination lens, which has the advantages of simple and reasonable structure, convenient use and good anti-counterfeiting effect.

Description

Adolescent myopia control glasses

Technical field

The utility model relates to a kind of glasses of correcting defects of vision, particularly a kind of glasses for the treatment of pseudo-myopia, preventing true myopia generation and development.

Background technology

Eyeball is looked near-ambient for a long time and is changed oneself for adapting to, and particularly is in the adolescent student of growth and development stage heavy learning tasks in parallel, and long-time close eye is the main cause that produces myopia; At the adolescent student of this age bracket quite a few being arranged is pseudo-myopia, can recover eyesight by treatment, can prevent to be transformed into true myopia by pseudo-myopia.

Prevent and treat myopia with regard to useful control glasses in the prior art and play the example of certain effect, as bifocals, progressive multi-focal lenses and lens type compound lens, but in use also have the following disadvantages: though two light or progressive multi-focal lenses are easy to use, alleviate human eye and looked closely adjusting burden in " three interlock ", but will gather, it is synchronous to have destroyed " three interlocks " physiology simultaneously again; The lens type compound lens can solve the problem synchronous with set of regulating, but can only see and use when near that the student read a book a little while takes notes last class hour in read-write; look at the blackboard a little while, need often change glasses, use very inconvenience; be difficult to adhere to that result of use is had a greatly reduced quality.For this reason, develop a kind of easy to use, rectification effect good, production and processing easily adolescent myopia control glasses are extremely urgent problems.

Summary of the invention

For overcoming the above-mentioned disadvantage that existing myopia preventing and treating glasses exists, problem to be solved in the utility model provide a kind of simple and reasonable, easy to use, treat pseudo-myopia and prevent the generation and the good adolescent myopia control glasses of development impact of true myopia.

The technical scheme that its technical matters that solves the utility model adopts, it comprises spectacle frame, is installed in the big eyeglass of myopia on the spectacle frame, the outside, below of described big eyeglass is provided with merges one or the protruding concave-sphere of splicing all-in-one-piece, be provided with fusion one or splicing all-in-one-piece arc prism with the corresponding big eyeglass of protruding concave-sphere inboard, the substrate of arc prism is towards nasal side, and protruding concave-sphere, big eyeglass and arc prism three form and the big different lens type compound lens of eyeglass diopter.

The optical centre of described protruding concave-sphere is lower than the optical centre of big eyeglass.

The handing-over line of described protruding concave-sphere and arc prism and big eyeglass is in the below at big lens optical center.

After adopting said structure, when seeing distant objects, can see distant objects clearly with the big eyeglass in top, to wear common spectacles the same with the people for this; When the books of seeing nearby just nature use lens type compound lens below the big eyeglass, the pleasing to the eye light of dispersing during read-write becomes the similar parallel rays far away of seeing, effectively got rid of and continued to look nearly the environmental factor that causes myopia with eye, alleviated and seen that human eye is regulated when near, the burden of set, make eyeball reduce the eye ciliary muscle contraction, in the time of accommodation reflex, really play the effect of convergence reflex in reducing, the also resilient axis oculi of growth is shortened a little, the eye ciliary muscle is removed nervous, be in relaxed state, curvature of lens diminishes, and recovers normal physiological function; The time of seeing written word accumulative total is long more, and oppositely regulating action is just big more, and recovery effects and prevention effect are just good more; After treating that near-sighted number of degrees decline is stable, should in time change the concave lens of the low number of degrees, be beneficial to further consolidate curative effect; Have simple and reasonable, wear easy to use, treat pseudo-myopia and prevent the generation of true myopia and advantage such as development impact is good.

Embodiment

Illustrated in figures 1 and 2, first kind of specific embodiments for a kind of adolescent myopia control of the utility model glasses, comprise spectacle frame 1, be installed in the big eyeglass 2 of myopia on the spectacle frame 1, the outside, below of described big eyeglass 2 is provided with merges one or the protruding concave-sphere 3 of splicing all-in-one-piece, be provided with fusion one or splicing all-in-one-piece arc prism 5 with protruding concave-sphere 3 corresponding big eyeglasses 2 inboards, the substrate of arc prism 5 is towards nasal side, and protruding concave-sphere 3, big eyeglass 2 and arc prism 5 threes form and the big different lens type compound lens of eyeglass 2 diopters; The optical centre of described protruding concave-sphere 3 is lower than the optical centre of big eyeglass 2; The handing-over line 4 of described protruding concave-sphere 3 and arc prism 5 and big eyeglass 2 is in the below of big eyeglass 2 optical centres.

Fig. 3 is the structural representation of the utility model eyeglass when undressed, and Fig. 4 is the B-B cross-sectional view of Fig. 3, and Fig. 5 is the C-C cross-sectional view of Fig. 3.Fig. 6 and Figure 7 shows that the other two kinds of specific embodiments of the utility model, its structural principle is identical with first kind of embodiment, no longer repeat at this, difference is protruding concave-sphere 3 and an arc prism 5 and handing-over line 4 positions of big eyeglass 2 difference to some extent, and the size of protruding concave-sphere 3 and arc prism 5 is difference to some extent.
