Abstract

The utility model discloses a lens for myopia treatment, wherein a prism is provided on one side of a concave lens, a larger plane of said prism is combined with the surface of the concave lens, and the other larger plane expands outward, so that the prism also forms a convex lens. The utility model is beneficial in that it enables the user to see far objects clearly and serves as physiotherapy, and also makes the user to read books comfortably and reduces the likelihood of fatigue.

Description

The bathomorphic eyeglass of a kind of treatment

Technical field

The utility model relates to the bathomorphic device of a kind of treatment, especially can prevent and treat the eyeglass of pseudomyopia.

Background technology

Myopia is the problem that present most people exist, and especially in the teenager, bathomorphic people occupies quite great proportion.Myopia has brought a lot of inconvenience for people's work and daily life.Myopia is divided into true myopia and pseudo-myopia, for true myopia, is difficult to cure by nonoperative method, and for pseudo-myopia, can be by assisting the method for physiotherapy to cure to the correct protection of eyes.It is that eyeglass is the glasses of convex lens that physiotherapy articles for use in the market have a kind of, and it is to utilize the imaging of convex lens to force eye's lens to be shunk to the opposite direction of myopia, thereby reaches therapeutic purposes.But the patient can't see distant objects clearly when putting on this glasses, can't see the word on the blackboard when for example the student wears clearly, so whenever inconvenience is all worn.In addition, when the student reads, book is placed on the desk, head need dip down, and sight line also needs downward-sloping certain angle, and it is all very tired to see that for a long time portion and eyes are exerted all one's effort in the gathering of calligraphers.

Summary of the invention

The technical problems to be solved in the utility model provides the bathomorphic eyeglass of a kind of treatment, utilize it both can see distant objects clearly, can see object nearby again clearly, can also reach the bathomorphic purpose of treatment, can make the wearer when reading, keep comfortable simultaneously.

The technical scheme that its technical matters that solves the utility model adopts is: the one side at concace mirror lens is provided with prism, the bigger plane of described prism and the surface combination of concavees lens, another is bigger towards outer lug, makes prism form convex lens simultaneously.

Described prism is positioned at below the concavees lens optical centre.

The direction of the Ji Ding of described prism upwards, being directed downwards of respective substrates.

The direction of the Ji Ding of described prism left, the direction of respective substrates is to the right.

The direction of the Ji Ding of described prism to the right, the direction of respective substrates is left.

Described prism and concavees lens are as a whole.

Owing to be provided with the additional eyeglass that convex lens and prism are combined together in the bottom of concace mirror lens, can be clearly seen that distant objects by concace mirror lens, nearby object can be seen clearly by the convex lens of bottom, the bathomorphic purpose of physical therapy treatment can also be reached simultaneously.In addition, when the wearer reads a book, under the refraction action of prism, the position of looking thing can be moved to the basic top of prism direction, thus the fatigue of minimizing reading person eyes.

The beneficial effects of the utility model are: both can allow the wearer see distant objects clearly, can reduce inwardly downward angle of wearer's eye sight line again, reach the physiotherapy purpose, can also allow the user comfortable when reading simultaneously, indefatigability.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the front view of a kind of embodiment of eyeglass of the present utility model;

Fig. 2 is a sectional view embodiment illustrated in fig. 1;

Fig. 3 is portion's view of the embodiment of a kind of implicit type structure of the present utility model;

Fig. 4 is a lens optical schematic diagram of the present utility model;

Among the figure, 1. concavees lens, 2. optical centre, 3. Ji Ding, 4. prism, 5. substrate.

Embodiment

As shown in Figure 1, at the optical centre 2 of concavees lens 1 to have a prism 4, prism 4 has two bigger faces and a less face, the surface combination of face that one of them is bigger and concavees lens 1 together, another is bigger towards locating projection, make prism 4 form convex lens simultaneously, as shown in Figure 2.Prism 4 can be made separately, combines with concavees lens 1 then, also can directly prism 4 and concavees lens 1 be made an integral body as shown in Figure 3.Preferred implementation is that prism 4 and concavees lens 1 are made an integral body, sees that from appearance prism 4 is stealthy, has both worn attractive in appearancely, and it is clear to look thing again.

Optical principle of the present utility model as shown in Figure 4, the base top 3 of prism 4 upwards, substrate 5 is downward, when the prism below the object A when the place ahead passes through and the eyeglass of convex lens one, because its refraction action, image A ' the meeting of the object A in the place ahead upwards and to the distant place is moved, and image A ' moves up wearer's eyes are looked squarely as far as possible, has reduced the fatigue of eyes; Image A ' moves the reverse contraction of the muscle place myopia that can force eye lens at a distance, thereby tempers crystalline lens flesh, corrects defects of vision.With the base of prism 4 top 3 towards left or right-hand or other direction, the image of the object in the place ahead also can to left or right-hand or Ji Ding towards other direction move, to adapt to different patients' needs.

Claims

1, the bathomorphic eyeglass of a kind of treatment, comprise concace mirror lens, it is characterized in that: the one side of described concace mirror lens is provided with prism, the bigger plane of described prism and the surface combination of concavees lens, another is bigger towards outer lug, makes prism form convex lens simultaneously.

2, the bathomorphic eyeglass of treatment according to claim 1 is characterized in that described prism is positioned at below the concavees lens optical centre.
