Abstract

The utility model discloses eyeglasses lenses. The eyeglasses lenses comprise lenses main bodies, wherein central optical regions are formed on the centers of the lenses main bodies; edge optical regions are formed outside the central optical regions; and the central optical regions are concave lenses. The eyeglasses lenses have the advantages that clear central vision is provided to a wearer by the central optical regions, and normal vision requirements of a patient with distant vision are ensured. Meanwhile, peripheral myopic defocus of the eyeballs of a patient with myopia are relieved by the edge optical regions, and irritant factors for worsening myopia are removed or relieved by the edge optical regions, thereby effectively delaying the worsening of the juvenile myopia.

Description

A kind of eyeglass
Technical field
The utility model relates to a kind of eyeglass.
Background technology
In order to obtain clearly central vision, the dioptric system of human eye must converge at the light of distant objects on the retina, if but eyeball is too crooked with respect to its outside surface oversize or eyeball for the focal length of axis oculi, thereby the parallel rays that causes distant objects to send (or reflection) has dropped on amphiblestroid front through the dioptric system refraction back focus of eyes, human eye just can not be seen object at a distance clearly, and it is ametropia that this has just formed Myopia.
The method of the myopia correction of current trend is a lot, but the whole bag of tricks all includes the defective that can't overcome separately: contact lens has the risk of corneal infection, and the long periods of wear somewhat expensive; There is larger spinoff in drug therapy; The excimer laser cornea refractive surgery treatment, although tool has certain effect on myopia correction, but make order aberrations obviously increase (home country's light: based on the vision correcting of wavefront aberration and the optical research of Extra Vision, Chinese science: 2007,5:595-604); Haplopia is corrected apart from eyeglass and is looked far away and look and all adopt same diopter when far away, increases the degree of fatigue of looking when near, increases myopic degree; Progressive multi-focus lens adopts progressive diopter from looking the far field near reading range, but only can myopia correction ametropia, the effectively intensification of retarding myopia.
Result of study according to U.S. Earl Smith professor, must take into account simultaneously the retinal periphery eyesight when heart eyesight under consideration during myopia correction, the zone keeps clear eyesight if foveal region of retina is looked nest, and peripheral retina maintenance is out of focus, can cause the elongated of eyeball and then cause myopia development.Fully confirmed the correctness of correlation theory about the independent studies report (Josh Wallman and Earl Smith) of chicken and monkey.Yet traditional myoporthosis eyeglass but can't be eliminated the stimulus of myopia development.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, provides a kind of and can effectively delay the out of focus eyeglass that adolescent myopia is deepened.
The utility model is achieved in that a kind of eyeglass, comprise the eyeglass body, it is characterized in that, Optical Region centered by the centre of described eyeglass body, the periphery of described central optical zone is until the marginal position of eyeglass body is the edge-light school district, described central optical zone is concavees lens, and the diopter of described edge-light school district increases progressively gradually to the diopter of central optical zone, incremental range is+and 0.50D~+ 3.00D.
Described central optical zone is divided into upper and lower two parts by horizontal axis, is two half-oval shaped, and wherein upside of ellipse is the glazing part, and lower semiellipse is lower light part; Described two semielliptical horizontal axis direction length are 15mm~20mm, and in the vertical axis direction, the glazing Partial Height is 4mm~5mm, and lower smooth Partial Height is 6mm~7mm, the diopter of described central optical zone be 0.00D~-8.00D.Described central optical zone provides clearly central vision for the wearer, guarantees A nearsighted person's the demand far away of looking.
The diopter of described edge-light school district slowly increases from edge to the diopter of lens edge with respect to central optical zone of described central optical zone, the scope that increases is+0.50D~+ 2.00D, its effect is the peripheral myopic out of focus of eliminating A nearsighted person's eyeball, thereby removes/alleviate the pungency factor of myopia development.
Central optical zone at eyeglass keeps radius-of-curvature relatively stable, near horizontal warp direction, keep the variation of radius-of-curvature evenly slow, thereby be implemented near horizontal warp direction surface astigmatism and central optical zone and maintain reduced levels, guarantee wearer's the clear and comparatively open visual angle of vision.
The beneficial effects of the utility model are: described central optical zone is traditional concavees lens design, and the central vision defective that is used for correcting the wearer is for it provides clearly central vision.The edge-light school district is distributed in the periphery of central optical zone, and for different rectification requirements, its peripheral edge Optical Region adopts the asymmetric design mode.Has lower surface astigmatism for central optical zone and along the peripheral edge Optical Region of horizontal warp direction.Can effectively delay adolescent myopia deepens.

Fig. 2 is the structural representation of the utility model embodiment.
Wherein: 1, eyeglass body; 2, central optical zone; 3, edge-light school district; 4, horizontal axis; 5, glazing part; 6, lower light part; 7, vertical axis.
Embodiment
According to Fig. 1, the utility model comprises eyeglass body 1, and Optical Region 2 centered by the centre of described eyeglass body 1, and the periphery of described central optical zone 2 is until the marginal position of eyeglass body 1 is edge-light school district 3, and described central optical zone 2 is concavees lens.Described central optical zone 2 is divided into upper and lower two parts by horizontal axis 4 with central optical zone 2, is two half-oval shaped, and wherein upside of ellipse is glazing part 5, and lower semiellipse is lower light part 6; Described two semielliptical horizontal axis 4 direction length are 15mm~20mm, and in vertical axis 7 directions, glazing part 4 highly is 4mm~5mm, and lower light part 5 highly is 6mm~7mm, the diopter of described central optical zone 2 be 0.00D~-8.00D.Described central optical zone 2 provides clearly central vision for the wearer, guarantees A nearsighted person's the demand far away of looking.The diopter of described edge-light school district 3 slowly increases from edge to the diopter of lens edge with respect to central optical zone 2 of described central optical zone, the scope that increases is+0.50D~+ 3.00D, preferably+0.50D~+ 2.00D, its effect is the peripheral myopic out of focus of eliminating A nearsighted person's eyeball, thereby removes/alleviate the pungency factor of myopia development.
The below is further elaborated the utility model according to specific embodiment.
Embodiment: according to Fig. 2, the glazing part 5 of central optical zone described in this example 2 is 4mm at the height of vertical axis direction, the height of lower light part 6 vertical axis 7 directions is 6mm, horizontal axis 4 direction length are 18 mm, the oblong fovea lens, diopter is-3.50 D, the diopter of described edge-light school district 3 is+2.00 D to the additional diopter of central optical zone 2, begin to deepen gradually all the other structures such as above-mentioned to the additional diopter in the edge of eyeglass body 1 from the periphery of central optical zone 2.
