Abstract
The utility model relates to a pair of full-view arc-top bifocal myopia control eyeglasses. In the eyeglasses, the diameter of a sub lens is set to 32 mm to 70 mm, so that visual field achieves full coverage when the eyeglasses are used for myopia; the distance between the vertex of the sub lens and the optical center of a main lens is set to 1 mm to 3 mm; and due to the higher position of the sub lens, the adverse effect on the effect of a prism with a downward substrate at the lower part of the main lens is reduced. Due to leveler arc lines at the upper part of the sub lens, comfort is also added when the eyeglasses are used for the myopia. By using the eyeglasses, both effects of clear hyperopia areas and scieropia treatment carried out to pseudo myopia are achieved and the growth of true myopia is effectively controlled.
Description
Technical field
The utility model relates to the bathomorphic device of a kind of control, especially can myopia correction, prevention and control myopia increases, and the characteristic glasses of treatment pseudo-myopia.
Background technology
The adolescent myopia problem more and more is social concerns in recent years, and many optics control products arise at the historic moment, and have their own characteristics each, and also obtain certain achievement.But also there are many uncomfortable, unfavorable problems of effect of wearing.With regard to two light microscopics, famous ophthalmologist, oculist, preceding group leader Mr. Xu Guangdi of Ministry of Education's whole nation myopia of student eye control expert's guidance group, show in " ophthalmology dioptrics " book at him and to point out: " with the pre-myopia prevention of bifocal lens, through observe for many years think can control true myopia really ".But in actual practice, also there are three problems in existing pair of light microscopic, the one, sub-optic diameter (26-28mm) less than normal closely uses visual field coverage rate little, produce sense of discomfort and bring some visual fatigues, the 2nd, sub-eyeglass summit has increased the downward prism degree in the end in time light apart from last photocentre 5-6mm, especially the unequal user of eyes diopter is brought more adverse effect, the 3rd, the camber line bending of sub-eyeglass summit is bigger, also produces uncomfortable property.More than 3 all can produce detrimental effect to the effect of myopia control.After changing the two light in arc top into, look and realized the full visual field when near, other two weak points also have clear improvement.
Summary of the invention:
The utility model is at the deficiency of existing control myopia and glasses for myoporthosis, particularly existing more existing disadvantages of bifocals, the reconstruction of the improvement of proposition form and diopter ADD utilization system, become arc top, the full visual field two light myopia control mirror, to be fit to higher requirement in the work of adolescent student control myopia.The utility model is because the increasing of sub-optic diameter, increased look nearly reading, the comfort level of eyes when writing, effectively alleviated kopiopia.Rebuild the utilization system of diopter ADD of nearly time spent of glasses simultaneously, the geometrical property that makes the pleasing to the eye light of nearly usefulness has been controlled the intensification of the near-sighted number of degrees better near the state of seeing when far away.The utility model adopts following technical scheme:
One, primary mirror sheet diopter 0.00DS～-15.00DS
Two, sub-optic diameter is less than 70mm greater than 32mm
Three, the last photocentre 1mm-3mm of sub-eyeglass summit distance
Four, sub-eyeglass diopter+2.00～-13.50DS
But five, sub-eyeglass and primary mirror sheet combined column mirror all.
Description of drawings:
Fig. 1 is arc top, the full visual field of the utility model two light myopia control glasses front views.
Fig. 2 and Fig. 3 are used lens structure size synoptic diagram.
Fig. 4 is this eyeglass side view.
1 mirror holder, 2 Jing Quan, 3 primary mirror sheets, 4 sub-eyeglasses, 5 primary mirror sheet photocentres, 6 sub-eyeglass summits, 7 sub-optic diameter among the figure.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the three-dimensional front view of the utility model, its mirror circle 2 height are greater than 26mm, and following spire point 6 is at Jing Quan half place highly, eyes are seen realized the full visual field when near, particularly descend the light visual field doubly, increased substantially the comfort level of looking when near than the big 2-3 of common double optical glasses.
Fig. 2 and Fig. 3 are the main part of the utility model-two light microscopic eyeglasses in arc top, the full visual field.
The utility model primary mirror sheet 3 luminosity reduce about 0.50D by the near-sighted number of degrees to be selected for use, and when wearing about one month, because eyes are subjected to the treatment and the protection of these glasses, it is just in time suitable that the near-sighted number of degrees generally reduce 0.50D.
Fig. 4 is that side view, its lens surface of the utility model eyeglass is level and smooth, attractive in appearance.
The selection of the sub-eyeglass 4 of the utility model will according to the wearer actual with eye distance from, be accustomed to eye, parameters such as eye position, adjusting power and height are determined, ADD is generally within+1.50D-+4.00D scope, the geometrical property of pleasing to the eye light is met substantially see the state when far away, effectively control the intensification of the near-sighted number of degrees.
The utility model has realized seeing visual field all standing when near because sub-optic diameter 7 is increased to 32-70mm (common just 26-28mm), for eyes created one more comfortable environment to alleviate kopiopia.Because the summit of sub-eyeglass so the downward harmful prism composition of substrate obviously reduces on sub-eyeglass 4, further alleviated the fatigue of eye near last photocentre 5 places again in 60 minutes.Simultaneously the top camber line flexibility of sub-eyeglass 4 reduces and has also increased the comfortableness of looking when near.
Realized efficient control by above measure, compared that its following additional optical ADD has mandatory, so better effects if with the progressive multi-focal mirror to myopia.
Presbyopia also increases many comfortablenesses as mentioned above when adopting the two light microscopic of this form.
