Abstract

The utility model belongs to cure and prevention technique for the ametropia of the eyes. The utility model has the technical scheme that the proposal to myopic treatment and prevention uses a compulsive hypermetropic method, and the proposal to hypermetropic treatment and prevention uses a compulsive myopic method. The half part of each of the lenses of the spectacles is a lighttight structure, the other half part is a euphotic structure, the lower half part of each of the lenses is a lighttight structure and the upper half part is flat lens or a concave lens structure with negative diopter or a convex lens structure with positive diopter. The structure proposed by the utility model has fine effects on curing and preventing the ametropia of the eyes.

Description

Be used for prevention and treat ametropic glasses

This utility model belongs to the not positive prevention of ophthalmic refractive, treatment technology, mainly proposes a kind of ametropic glasses that are used for preventing and treating.

Teen-age in recent years near-sighted sickness rate raises day by day, has a strong impact on teen-age growing up healthy and sound, and also becomes the unfavorable factor of the learning life that influences them and work and study in the future, and this phenomenon has caused the concern of the relevant department and the whole society.For the formation reason of myopia, the inventor thinks: 1, due to the changeableness of eyeball.The profile of lesser ring of Merkel cornea is an almost spherical, and its thickness has only 0.5mm.Its back to crystalline distance is 3.1mm, is the filling of aqueous humor institute entirely.Its pressure is 10～21mmHg under the normal condition.The thin soft back that adds of cornea is the aqueous humor that pressure is arranged.So see in the near process in adjusting, the curvature of contracted pupil and cornea is increased, this just must oppress aqueous humor and push forward, the curvature of cornea is increased more, the anteroposterior diameter of eyeball is justified and elongated to the point more that eyeball is become, after secular frequent reading and writing, only just formed and to have seen closely and can not see myopia far away.Lamplight brightness during its two reading learning is not enough or white light (daylight lamp) is dazzling, and contracted pupil and corneal curvature are increased, and this is circular and the optical axis is increased with regard to aqueous humor must being extruded make forward eyeball to become point.Concavees lens are to dwindle effect to what closely play, though so can see thing phase at a distance immediately clearly after putting on recessed near-sighted glasses, but reduce again at once and hope near vision, can only remove to see clearly in-plant writing with more approaching the mode literal and blink of frowning, and this will more elongate the anteroposterior diameter of eyeball, and the diopter of eye is more and more raise.The reason that hypermetropia forms is all to degenerate to soft unable stage because of muscle group, fascia inside and outside the eyeball, the increase of the obstruction of artery and vein blood vessel and blood vessel wall permeability, after causing that eyeball expands, make the lesser ring of Merkel corneal curvature reduce the back and can't see the oculopathy of fines phase nearby clearly.And be must be with shortening eyeball back/forth diameter, shortening the method for watching attentively that enlarge palpebral fissure apart, enlarge pupil for the prevention of myopia and treatment, then opposite for the prevention of hypermetropia with treatment.

The purpose of this utility model promptly is to propose a kind of ametropic glasses that prevent and treat, and makes it to ophthalmic refractive better therapeutic effect just not arranged, and ametropia is had preventive effect preferably.

The technical scheme that the utility model proposes is: treatment and prevention scheme to hypometropia are mandatory methods with hypermetropia, treatment and prevention scheme to the eyes hypermetropia then are mandatory methods with myopia, half one of its eyeglass of glasses that the utility model proposes thus is light tight structure, and half one is a translucent construction in addition.

According to this technical scheme:

The first half of eyeglass is not for there being dioptric flat mirror structure, and Lower Half is light tight structure, makes to go to read, watch attentively by glasses top, promptly adopts the method for hypermetropia, and this glasses are used to prevent the generation of hypometropia.

The first half of eyeglass is for having negative dioptric concavees lens structure, and Lower Half is light tight structure.The optical center of first half concavees lens is positioned at the center of whole eyeglass.This lens structure is used for the treatment to hypometropia.

The first half of eyeglass is light tight structure, and Lower Half is the convex lens structures that has positive diopter, is used for the treatment to the eyes hypermetropia, can mandatory method reading learning with myopia.

The first half of eyeglass is the convex lens structures that has positive diopter, and Lower Half is light tight structure, in order to cooperate with the hyperopic treatment mirror, prevents that the farsighted person from producing bad influence with the method for watching attentively of myopia to eyes for a long time.

The prophylactic treatment glasses that employing the utility model proposes, fundamentally change myope and farsighted person's the method for watching attentively, promptly force myopia with the method for watching attentively of hypermetropia, hypermetropia is with the near-sighted method of watching attentively, thereby near-sighted, farsighted person are had better therapeutic effect and preventive effect.What the utility model proposes is simple in structure and scientific and reasonable, has positive role for solving the ametropic prophylactic treatment of teenager.

Embodiment:

Accompanying drawing 1 is embodiment 1 structural representation.

Accompanying drawing 2 is embodiment 2 structural representations.

Accompanying drawing 3 is embodiment 3 structural representations.

Accompanying drawing 4 is embodiment 4 structural representations.

The accompanying drawing that provides with reference to embodiment 1-4 is further specified its structure:

As shown in Figure 1, the first half 2 of eyeglass 1 is not for there being dioptric flat mirror structure, and Lower Half 3 is light tight structure.The upper and lower part eyeglass can be the eyeglass that is made into integration, and promptly can be the flat mirror structure that is made into integration, and the Lower Half eyeglass is done light tight processing get final product.Also can adopt the special lens material, make the Lower Half eyeglass as broad as long with first half eyeglass in appearance, but be light tight structure actually.This lens structure is in order to play the effect of pre-myopia prevention.

As shown in Figure 2, the first half 5 of eyeglass 4 is for having negative dioptric concavees lens structure, and Lower Half 6 is light tight structure.Its optical center of the concavees lens of the first half is positioned at the center of full wafer eyeglass.It is used for the treatment to hypometropia.

As shown in Figure 3, the first half 8 of eyeglass 7 is light tight structure, and Lower Half 9 is for having the convex lens structures of positive diopter.Its optical center of the convex lens of Lower Half positive diopter is positioned at the center of eyeglass.It is used for the treatment to the low hypermetropia patient.

As shown in Figure 4, the first half 11 of eyeglass 10 is the convex lens structures of positive diopter, and its optical center is positioned at the center of eyeglass.Lower Half 12 is light tight structure.Its glasses with embodiment 3 cooperate, and are used for the treatment to the low hypermetropia patient equally.
