Description
Technical field
The utility model relates to the near-sighted prevention and control mirror technical field of eyes, particularly relates to a kind of myopia progression controlling periphery out of focus and controls glasses.
Background technology
Myopia, refers to that target image at a distance focuses on retina front, thus causes distant vision fuzzy, is a global eyesight difficult problem, in the crowd of all age levels, all nationalitys, all can occurs this visual problem.
There are some researches prove that peripheral retina long sight out of focus and myopia degree are constantly deepened to have close relationship, long sight out of focus on peripheral retina has promoted the Gabor transform of eyeball, myopia degree is deepened, and the Myopia out of focus of peripheral retina can reduce the elongated speed of axis oculi, control, slow down the development of myopia.
Prove through correlative study, traditional eyesight solution all focuses on control center's eyesight, and object is just to provide good central vision.But although traditional single vision lenses can correct central vision, its periphery can be made to project to retina rear.Retina will be impelled like this to extend backward, accelerate the speed that axis oculi is elongated.This also just explains, and why some children myopia degree after wearing single vision lenses increases all the more fast.Up-to-date research has changed the understanding for myopia: the mode of correcting central vision simultaneously and controlling peripheral retina long sight out of focus is only the most effective way controlling and slow down myopia progression, and vision and myopic optical defocus are all reduce the powerful expulsive force that eyeball increases clearly.
Existing periphery out of focus controls eyeglass Shortcomings in central field of vision scope and the property worn, accurately do not consider to make the optimum field scope in vision correction district of frame eyeglasses rear center and the area ratio of shape and rectification district, center and periphery out of focus control zone, do not consider that lens periphery light refraction that picture frame periphery printing opacity causes is on the impact of effect, periphery out of focus can not be reached and control and the best resultant effect of the property worn yet.Prior art selects for the area of rectification district, center and periphery out of focus control zone and ratio does not have clear and definite standard, and area is too small, then visual field deficiency, impact is worn, the area in rectification district, center is excessive, then can not ensure that eyeglass has enough periphery out of focus control areas, not have optimum efficiency.The shape in the rectification district, center of prior art mostly is circular, as patent CN201020253877.9.And the human eye angular range (+25 ° ~+30 °) that level is converge like the spokes of a wheel at the hub when looking thing is much larger than the angle (2 △-4 △) of vertical direction, therefore circle be not meet human eye engineering science and people soon far away, when seeing near converge like the spokes of a wheel at the hub, separately with the optimal selection of the positive permelting such as vertical as scope rule, circle takies too much area in vertical direction simultaneously, have impact on the control effects of periphery out of focus.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in the figure: a kind of myopia progression controlling periphery out of focus controls glasses, hereinafter referred to as this glasses.This glasses comprise picture frame 2, temple 1 and eyeglass 3, and eyeglass 3 is Shuan Guang district eyeglass, and eyeglass 3 is divided into eyeglass central optical zone 5 and lens periphery Optical Region 4, and eyeglass central optical zone 5 is less than 1/2 with the area ratio of lens periphery Optical Region 4; Eyeglass central optical zone 5 is positioned at eyeglass central part, is prepared as oval concavees lens, and power range is-20D ~ 0D, and oval minor axis length scope is 15mm ~ 45mm, and long axis length scope is 18mm ~ 45mm, and major axis is positioned at horizontal direction.Lens periphery Optical Region 4 is positioned at lens periphery position, is prepared as convex lens sheet, and power range is+1D ~+4D; Preferably preparing power range is+1.5D ~+3D; Oval concavees lens overlap with the optical centre of convex lens; The junction of eyeglass central optical zone 5 and lens periphery Optical Region 4 is gradually Zoom structure or notch cuttype Zoom structure.The frame of picture frame 2 is full frame, and color is lighttight dark color.
After deliberation: the diopter Φ of lens periphery Optical Region 4
1the diopter Φ of (being more than or equal to 0D) and eyeglass central optical zone 5
2the pass of (being less than or equal to 0D) is: Φ
1=+4D+a × Φ
2, a is coefficient; Span is :-3D≤Φ
2during≤0D, 0.5≤a≤0.7;-6D≤Φ
2during <-3D, 0.3≤a≤0.5; Φ
2during <-6D, 0.1≤a≤0.4.This glasses are more easily prepared.
This glasses, lens periphery Optical Region is positioned at lens periphery position, is prepared as convex lens sheet, for controlling retinal periphery long sight out of focus, controls myopia progression.Eyeglass central optical zone is positioned at eyeglass central part, is prepared as oval concavees lens, ametropia for correcting retinal centre, provides good central vision; According to human eye retina's central authorities' macular area and the Position Design eyeglass central optical zone of the non-macular area of periphery and the area ratio in peripheral optical district, region for eyeglass utilizes more scientific and reasonable, oval concavees lens overlap with surrounding zone convex lens optical centre, on mirror holder is selected, select the lighttight full frame design of black, effectively can prevent the impact of astigmatism on control effect of lens periphery.After frame eyeglasses made by above-mentioned eyeglass and special mirror holder; central optical zone adopts elliptical shape; more meet human eye shape, its shape and size design taken into full account people soon far away, when seeing near converge like the spokes of a wheel at the hub, separately with the positive permelting image angle degree scope such as vertical, meet visual field demand during people's normal activity.The problem that the slight dizziness that may occur when not wearing progressive lenses, space sense change, change to the Distance Judgment of object, depth preception.There is better myopia progression control effects compared to existing technology.The teenager being more suitable for myopia wears.
