The beneficial adjustment can gradually reduce the diopter of the myopia of the teenager and the children.

Description

Prevention and control glasses

Technical Field

The utility model relates to a glasses specifically are prevention and control glasses.

Background

Long-time reading at close range can cause eye fatigue and further eye distension. The closer the object is, the stronger the traction is, the more tense the ciliary muscle is, and the increase in the degree of myopia may be formed over a long period of time. Simultaneously, the optometry standard is 5 meters apart from, and the optometry degree that so is for seeing far distance luminosity, and closely read mostly between 30~40 centimetres, for seeing the short-range object of looking clearly, the eyes still need to use the regulation when the different sets of near-range use along with the object distance of looking, and then aggravate the formation of eye fatigue and increase near-sighted growth rate. Both chinese patents 99234597.9 and 201020152497.6 propose the concept of prism plus ball glasses, which are designed to be magnetically attached externally and composed of two lenses, so that the glasses are heavy and troublesome to wear.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a prevention and control glasses to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a prevention and control glasses, includes picture frame and lens, the lens includes distance optical power lens and short-distance optical power lens, and the distance optical power lens is located short-distance optical power lens top, place the inside little prism of basement in the distance optical power lens, be provided with the inside big prism of basement in the short-distance optical power lens.

As a further aspect of the present invention: the lens is designed in an integrated mode, the edge segmentation processing is carried out on the small prism and the large prism, and the power is adjustable.

Compared with the prior art, the beneficial effects of the utility model are that:

can eliminate the regulation, aggregation, convergence and tension states of the glasses in the near vision dioptric system, avoid the eye fatigue and increase the diopter, and effectively prevent the occurrence and the development of the myopia. The beneficial adjustment can gradually reduce the diopter of the myopia of the teenager and the children.

Can make two-layer glasses become the one deck, still more pleasing to the eye comfortable when promoting light practical, make teenagers and children still accept more easily when preventing and controlling the diopter.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

It should be noted that, if there is a directional indication (such as up, down, left, right, front, and back) in the embodiment of the present invention, it is only used to explain the relative position relationship between the components, the motion situation, etc. in a certain specific posture, and if the specific posture is changed, the directional indication is changed accordingly.

Example 1

Referring to fig. 1 to 3, in an embodiment of the present invention, a pair of prevention and control glasses includes a frame 5 and lenses, the specific types of the lenses are not limited, in this embodiment, preferably, the lenses include a distance-luminosity lens 1 and a near-luminosity lens 2, the distance-luminosity lens 1 is located above the near-luminosity lens 2, a small prism 4 with an inward base is placed in the distance-luminosity lens 1, and a large prism 3 with an inward base is placed in the near-luminosity lens 2.

Further, the lens formula design as an organic whole, little prism 4 and big prism 3 carry out edge segmentation processing and the power is adjustable, can make glasses like this lighter practical to it is pleasing to the eye comfortable.

The utility model discloses a theory of operation is:

1. the lens has different upper and lower powers, and the upper distance power lens 1 is the power obtained by looking at distance, namely the 5 m distance of refraction. The lower low-beam lens 2 is used for seeing the low-beam, namely, the beam at a distance of 30-40 cm. Therefore, the problem of adjustment is solved firstly, so that the people can see far and near without using excessive adjustment, and the eyestrain is effectively relieved.

2. The lens is added with a prism, according to the principle that different visual object distances use different sets, a corresponding prism is added in the area of the lens for seeing the near luminosity, and an object moves towards the base by utilizing the principle of light refraction so that the near vision is changed into the telescopic vision. The less so of using the set of when seeing far of binocular sees far adds the prism degree that optometry obtained in the lens is seen the distance optical power region, makes to see far and becomes to see infinitely far away, has both solved the eyes like this and has adjusted the problem and still solved and see nearly set problem to compromise and see far and see the different and different problems of luminosity of nearly set, make eyes fully relax, effectively reduce the production of asthenopia, thereby play the increase that prevents, control the near-sighted degree.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
