Abstract
The utility model relates to a one-line bifocal myopia control lens. The one-line bifocal myopia control lens comprises a concave lens (1) and a prism (2), wherein the concave lens (1) is arranged in an upper half area; the prism (2) is arranged in a lower half area; the concave lens (1) and the prism (2) are different in diopters; the concave lens (1) and the prism (2) are integrated as a whole; a base of the prism (2) faces to a noise side; a junction line (3) between the concave lens (1) and the prism (2) is located in the center of the lens; the prism degree of the prism (2) is 6cm/m. The one-line bifocal myopia control lens is capable of loosening adjusting force and convergence power and reducing the degree of fatigue of two eyes for seeing near three linkages, thus avoiding the growth of the myopia.
Description
Technical field
The utility model relates to the two light myopia control prossives of an a kind of line.Belong to optometry and join mirror technology and medical health care products technical field.
Background technology
When a people is when due to age growth, eye adjusting power weakens, just need to be to depending on far away and depending on making closely respectively vision correction, at this moment often need to join two pair of glasses and wear respectively use, this is just very inconvenient, therefore produced two kinds of different refractive powers have been ground on same eyeglass, become the eyeglass in two regions, this eyeglass is just called two light microscopics.
Human eye is seeing time far away, and eyes are in relaxation state, and (beyond 5 meters) parallel rays at a distance sees through ocular focusing on the retina of eyeground, thereby sees object clearly by brain imaging.
Eyes are seen near time in running order: 1, the work of intraocular flesh makes crystalline lens become protruding (adjustings), 2, extraocular muscle work makes to gather in eyes sight line aim at the mark (set); 3, papillary sphincter muscle work makes myosis, and above state is referred to as " seeing nearly three interlocks " on optometry.
But along with the develop rapidly of modern society, make people see that near probability and time are more and more, the time that namely eyes " are seen nearly three interlocks " is more and more, and eyes cause kopiopia in nervous duty for a long time, thereby cause axial growth, finally can cause myopia to increase.
A traditional line Bifocal lenses is to aim at presbyopia on a pair of glasses, to see far simultaneously, see the different diopter design of nearly needs.Presbyopia is seen nearly adjusting power deficiency because the decline of intra-ocular lens adjusting power causes, so the two light of design one line sees that near region (bottom half) arranges convex lens and supplements not enough adjusting power, this kind of structure is seeing when near, be equivalent to be with a pair " presbyopic glasses ", only have convex lens to work, the adjusting in real reduction " seeing nearly three interlocks " and congregation zone be not to the fatigue of eyes, and the myopia of eyes still can increase.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of pair of light myopia control prossive is provided, and this eyeglass can effectively reduce the fatigue of eyes, has avoided bathomorphic growth.
The purpose of this utility model is achieved in that
The two light myopia control prossives of an a kind of line, be characterized in: the concavees lens of upper half and the prism that is positioned at bottom half, described bottom half adds light+3.0 diopter under being, described concavees lens and prism combine together, the substrate of described prism is towards nasal side, the handing-over line of described concavees lens and prism is positioned at eyeglass central authorities, and the prism degree of described prism is 6 cm/m.
The two light myopia control prossives of an a kind of line of the utility model, when assembling, handing-over line 2mm under pupil.
Compared with prior art, the beneficial effects of the utility model are:
The two light myopia control prossives of an a kind of line of the utility model, utilize eyeglass bottom half under add light+3.0 diopter (D) and can compensate for 100% the required adjusting power of eyes, utilizing base-in prism degree is that the prism of 6 cm/m can be offset and loosened set, wherein retain 1/3 convergence power, can more be conducive to prevent the outer oblique growth of eyes recessiveness.Therefore utilize eyeglass of the present utility model just can loosen adjusting power, convergence power, reduce the degree of fatigue that eyes " are seen nearly three interlocks ", thereby avoided bathomorphic growth.

Handing-over line 3.
Embodiment
Relate to the two light myopia control prossives of an a kind of line referring to Fig. 1-4 the utility model, it comprises the concavees lens 1 of upper half and is positioned at the prism 2 of bottom half, described bottom half adds light+3.0 diopter (D) under being, described concavees lens 1 and prism 2 combine together, the substrate of described prism 2 is towards nasal side (end, is inside), the handing-over line 3 of described concavees lens 1 and prism 2 is positioned at eyeglass central authorities, and the prism degree (△) of described prism 2 is 6 cm/m.
Wherein, in eyeglass when assembling, joins line 3 and is located at 2mm place under pupil, so effectively guarantees to see that the visual field when near is in control zone.
Principle of work: eyes interpupillary distance 60mm, in the time seeing nearly 33cm target, the adjusting power of need employ+3.0 diopters of eyes (D), the convergence power (simple eye prism degree is 9 cm/m) of 18 cm/m prism degrees, just can reach eyes relaxation state (pleasing to the eye light=parallel rays).The utility model, seeing that when near, simple eye prism degree is 6cm/m, has loosened 67% convergence power, has substantially reached relaxation state (pleasing to the eye light=parallel rays), wherein retains 1/3 convergence power, can more be conducive to prevent the outer oblique growth of eyes recessiveness; Because the bottom half of eyeglass adds light+3.0 diopter (D) under being, therefore offset eyes required+the adjusting power (offsetting 100%) of 3.0D.
The utility model is seen when near at eyes, utilize eyeglass bottom half under add light+3.0 diopter (D) and can compensate for adjusting power, utilizing base-in prism degree is that the prism of 6 cm/m can loosen 67% the required convergence power of eyes, therefore the utility model can loosen adjusting power, convergence power, reduce the degree of fatigue that eyes " are seen nearly three interlocks ", thereby avoided bathomorphic growth.
Claims (2)
1. the two light myopia control prossives of line, it is characterized in that: described eyeglass comprises the concavees lens (1) of upper half and is positioned at the prism (2) of bottom half, described bottom half adds light+3.0 diopter under being, described concavees lens (1) and prism (2) combine together, the substrate of described prism (2) is towards nasal side, the handing-over line (3) of described concavees lens (1) and prism (2) is positioned at eyeglass central authorities, and the prism degree of described prism (2) is 6 cm/m.
