Description

Eye health glasses

The utility model relates to a kind of Eye health glasses, belongs to the monochromatic light with prism effect and closely uses glasses.

The bathomorphic cause of disease of people mainly is to cause owing to looking nearly overlong time.The normal person looks when far away, and eyes are regulated with set and all are in resting state.When human eye is looked nearby object view, produce adjusting, set and miotic reaction, it is moving to be referred to as near reflex three through transports, the 3rd pair of cranial nerve all accepted in these three kinds of motions--the oculomotor nerve domination, especially regulate with set by the domination of A Peili nuclear.When human eye is looked near thing, the intraocular ciliary muscle contraction, it is protruding that crystal becomes, and index of refraction increases, and makes the object light nearby also can imaging on retina, closely makes ciliary muscle continue to shrink and spasm but look for a long time, forms accommodative myopia, is commonly called as pseudo-myopia.If this situation is not corrected, regulate burden and can not get for a long time alleviating, make with regard to compensatory ground that the rear axle lengthening is to adapt to this change at the moment, the formation axial myopia is commonly called as true myopia.So people just wear spectacles after myopia forms.

The ultimate principle of the instrument of the many control myopia that occur up to now on the market mainly contains: 1, massage, electric pulse stimulation acupuncture point, 2, Chinese herbal medicine is local infiltrates, 3, magnetic stimulation, 4, Micropole glasses, 5, oppression eyeball, 6, simple convex lens mist is looked therapy etc. and all can not be produced good preventive and therapeutic effect at the cause of disease and the pathogenesis of myopia, and is that have even harmful to eyes.

Spectacles are now seen far and have been known, see closely again and regulate, and look the immediate cause element for a long time if can not eliminate, and just repeat former process again, make spectacles wear darker and darker.If see far and wear glasses, see and closely do not wear mirror, though see and need not regulate when near, but need set (two inwardly), because the connected effect of adjusting and set, set drives adjusting, making regulate to increase and deepens myopia, simultaneously also can owing to set weaken produce outer squint to.

China utility model patent CN87208013U and CN2168268Y disclose " few eye health glasses " and " control myopia three is used glasses " respectively, the former by up and down two constitute, it last slice be concavees lens, to correct distant vision, its down sheet be convex lens and the inside prism of substrate than last slice positive 3D, replace eye to finish seeing adjusting when near with the convex lens of positive 3D, the inside prism of substrate makes sees that oblique light of going into two becomes the light of vertically going into two when near, to alleviate polymerization, but eyeglass is set in the picture frame up and down, in case the picture frame screw is loosening, eyeglass scatters and jeopardizes eyes; Do not have buffering between two eyeglasses and easily collapse brokenly, be not durable and easily hinder eyes; The slit that disconnection is arranged between two eyeglasses, attractive in appearance as the eyeglass of having gone bad.

Latter's " control myopia three is used glasses " is at complete sheet (10) bottom gummed or fuses small pieces (9), small pieces are+prism (seeing Fig. 1 and 2) of 1～3D convex lens and compound 3 Δs, more thick and heavy, outward appearance is not beautiful, and eyeglass (9 and 10) joint has the ditch crack easily to retain foul; The bifocal of upper and lower (9 and 10) often can not involutory pupil center, produces sense of discomfort when taking a fancy to apart from object by the optics separatrix when sight line moves up and down.

The purpose of this utility model be avoid the deficiencies in the prior art part and provide a kind of simple and clear efficient, safety is light, both artistic and practical, the Eye health glasses of prevention and treatment myopia.

The utility model include two by single transparent optical glass or transparent optical resin grind form, the cross section is half moon-shaped plated film or non-plated film monochromatic light lens, connect by the nose frame between these two monochromatic light lenses, respectively be provided with the mirror leg on its two outside or this two monochromatic light lenses are embedded in the frame, described two monochromatic light lenses are interior eccentric convex lens or outer eccentric concavees lens, and using the rib plating degree at position at it is that 1.5～8 Δ substrates are inside.

According to the long sight of people's optometry, myopia or astigmatic diopter with look closely to reach and regulate and collective ability, determine diopter of the present utility model and prism degree, adopt corresponding optical lens, to produce desirable strong eye effect.

Adopt interior eccentric convex lens for the patient who needs convex lens, then adopt outer eccentric concavees lens for the patient who needs concavees lens.According to GB10810-1996 neq ISO 8980-1:1996 standard, the definition of monochromatic light lens is to have the eyeglass (as concave-sphere, post mirror, goalpost mirror) of haplopia apart from ability, and monochromatic light lens of the present utility model adopts cylindrical lens or spherocylindrical lens then to be applicable to the patient who needs astigmatism.

Eccentric convex lens are formed with the prism 8 (seeing Fig. 5 and 6) that outer eccentric concavees lens all are equivalent to the inside different prism degrees of a lot of substrates in of the present utility model, use position 6 to have inside (direction of arrow among Fig. 5 and 6 is represented) prism degree of substrate of aequum at it, adjust eyeglass when joining mirror and use position 6 accurate involutory eye pupil 7 points.Eyeglass uses determining of position 6 prism degree: then adopt 1.5～4 Δ substrates inside for computation with mirror; Then adopt 2～6 Δ substrates inside for reading and writing with mirror; For then in the inside scope of 1.5-8 Δ substrate, adjusting the apolegamy use with regulating with the unusual person of consolidation function.

At present, above-mentioned all kinds of persons suffering from ocular disorders is prepared long sight, myopia or the astigmatic glasses of the corresponding number of degrees merely according to the optometry situation.Though look when far away clearly, looking still needs to regulate fully and gathers when near, therefore wears mirror and looks nearly thing time one and longly promptly produce tiredly, and makes myopia more and more darker.The utility model replaces human eye to look the major part adjusting and set of nearly thing with the diopter and the prism degree of its single vision lenses, changes the human eye light of the human eye light one-tenth of near objects than far object, thereby reduces near-sighted paathogenic factor greatly.

The utility model compared with prior art has following advantage:

1, single vision lenses of the present utility model is made with homogenous material, without any need for applying, composes fusion, and eyeglass is frivolous, and eyeglass does not have picture frame or is embedded in the cell mount, and outward appearance is simple and clear, attractive in appearance, light and handy, practical.

2, the monochromatic light glasses are single focus glasses, and the use position gets final product accurately and pupil is involutory as long as suitably adjust.

3, the utility model not only is fit to the normal person, also is fit to various ametropes, according to each one dioptric (long sight, myopia, astigmatism) situation, adopts the respective optical lens, determines diopter and prism degree, promptly produces desirable key eye effect.

4, the utility model has fatigue symptom or insufficiency person to regulating with set, also can suitably adjust diopter and prism degree, rescues, and eliminates symptom.

5, wear with behind the utility model, also visual far away, when looking, then can make image formation by rays at a distance before retina than the distant view thing, amphiblestroid picture is unclear, can force ciliary muscles relax, and accommodative myopia can be cured like this.

6, the alternative traditional presbyopic glasses of the utility model, because the elderly's adjusting power goes down, collective ability is also faded.Traditional presbyopic glasses only can help to regulate.The utility model not only can help to regulate and also can help set, wear mirror after read-write more comfortable.
