Abstract

The utility model discloses zoom glasses which are suitable for the myopia or hyperopia prevention and treatment. The utility model can overcome weaknesses in prevention and treatment for myopia in prior common glasses, therapeutic instruments, ophthalmic solution for myopia, etc. The lens (2) of the zoom glasses are attached with a layer of transparent elastic zoom tablet (4) which forms a contractible cavity (5) together with the lens (2). The closed cavity (2) is connected with a catheter (6) for transporting liquid. The terminal of the catheter (6) is an elastic vacuole (7) which is placed between an electromagnet (8) and an iron sheet (9). The power supplying and cutting off of the electromagnet is controlled by an adjustable timing control circuit. The utility model can alter the focal length of the glasses, as a result, can constantly exercise the lens and the ligament to effectively guard against and treat the myopia.

Description

Zoom glasses

Technical field

This utility model relates to a kind of glasses, especially a kind of Zoom glasses that is applicable to prevention and treatment myopia or hypermetropia.

Technical background

Because heredity and Effect of Environmental, in recent years, the teen-age near-sighted sickness rate of China is high.Show that according to relevant department's recent statistics numeral national pupil's myopia sickness rate reaches 13.6%, middle school student reach 46.25%, and the university students reaches 70% more than.

Cause the reason of myopia of student a lot, many ophthalmologist oculists are consistent to be thought, because student's school work is heavy, study is long positioning time of reading a book closely, add some students operate video games mechanical, electrical brain, surf the Net or see TV, excess eye-using, cause ophthalmic nerve fatigue, the eyeball blood supply insufficiency causes the crystalline lens laxity of ligament, motility is gone down, and makes visual deterioration.This myopia medically is referred to as accommodative myopia, is commonly called as pseudomyopia.The number of degrees of myopia of student are also not dark in such cases, naked apparent 0.6, and diopter is about 100 degree.Also have the more myopia of student time longer, what have has all worn glasses for the shortsighted, even the minority myopia number of degrees are also very big, and this will have a strong impact on myope's study, work and life.

Summary of the invention

This utility model is intended at the deficiency to the prevention and the medical treatment of myopia such as existing average eye, therapeutic instrument, treatment myopia medicinal liquid, a kind of Zoom glasses of adjustable focal length is provided, this Zoom glasses is owing to can change the glasses focal length, so can constantly movable crystalline lens and ligament, so can effectively prevent and treat myopia.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of Zoom glasses comprises spectacle frame, eyeglass, it is characterized in that: be attached with on the eyeglass layer of transparent and eyeglass between have the zoom sheet of closed cavity, described closed cavity is connected with squeeze fluid device through conduit, in closed cavity and conduit transparency liquid is arranged.

Described zoom sheet is an elastomer, and the terminal of described conduit is a rubber-like vacuole.

Described zoom sheet is positioned at eyeglass middle part, and is affixed with eyeglass around it, forms contractile cavity between middle part and the eyeglass, and liquid fills that expandable cavity outwards protrudes in wherein the time.

Described squeeze fluid device comprises electric magnet, the iron plate that cooperates with electric magnet, and described vacuole places between electric magnet and the iron plate.

The power supply of described electric magnet is an aneroid battery, an adjustable timing control circuit is arranged, the break-make of timing controlled power supply on this circuit.

The beneficial effects of the utility model show:

This utility model is switched on by self-timing, makes in the coil to produce the magnetic field suction iron plate and push vacuole, and the zoom sheet is outwards protruded, and has so just changed the diopter of glasses for the myopia.Myope or pseudomyopia patient in regularly frequent zoom process, make eye's lens and ligament often be in a kind of kinestate with going up such eyes, and eye movement is spirit then, and so lenticular elasticity is just good more, can give the eyeball blood supply well, lessens fatigue.So can be used for preventing real myopia by wearing Zoom glasses pseudomyopia person, the myope can be used for treatment myopia, the people's use that is particularly useful for the student and bends over one's desk working.

The specific embodiment

A kind of Zoom glasses, comprise spectacle frame 1, eyeglass 2, be attached with the elasticity zoom sheet 4 of layer of transparent on the eyeglass 2, can adopt plastics, rubber or other elastic apparent materials to make, bonding around it with eyeglass 2, form contractile cavity 5 between middle part and the eyeglass 2, described closed cavity 5 is connected with the conduit 6 of a transfusion, the terminal of conduit 6 is a rubber-like vacuole 7, and vacuole 7 is connected with squeeze fluid device, in closed cavity 5 and conduit 6 (vacuole 7) transparency liquid is arranged.Described squeeze fluid device is made of electric magnet 8, the iron plate 9 that cooperates with electric magnet 8, and described vacuole 7 places between electric magnet 8 and the iron plate 9.The power supply of electric magnet 8 is an aneroid battery, and an adjustable timing control circuit is arranged on this circuit, the break-make of timing controlled power supply, and adjustable timing control circuit adopts existing integrated package, can purchase on the market.

It is logical once that this utility model can be set per 10 seconds, when timing control circuit is given electric magnet 8 coil electricities, electric magnet 8 produces magnetic field suction iron plate 9 extruding vacuoles 7, making the transparency liquid (as pure water) in the vacuole 7 is that the fibre conduit 6 of 0.5 ~ 3mm passes in the cavity 5 between eyeglass 2 and the zoom sheet 4 by diameter, liquid fills in wherein the time, and cavity 5 expands and outwards protrudes, thereby changes the diopter of glasses, one time the zoom process approximately kept for 2 seconds, and zooming range is between eyeglass lens power and zero diopter.In regularly frequent zoom process, make eye's lens and ligament often be in a kind of kinestate, eye movement is spirit then, and so lenticular elasticity is just good more, can give the eyeball blood supply well, lessens fatigue.So can be used for preventing real myopia by wearing Zoom glasses pseudomyopia person, the myope can be used for treatment myopia, the people's use that is particularly useful for the student and bends over one's desk working.When electric magnet 8 was not switched on, zoom sheet 4 restored to the original state under the elastic force effect, became a secondary common spectacles, can use as usual.
