Description
Technical field
The utility model relates to the near-sighted prevention and control mirror technical field of eyes, particularly relates to the near-sighted prevention and control glasses of a kind of zonal control central vision and peripheral visual acuity.
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 allowed to have projected to retina rear, cause the long sight out of focus of peripheral retinal region.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.
The retina of human eye is divided into central field of vision district and peripheral visual field district, has different optic nerve cell categories, is responsible for the imaging of human eye central field of vision and peripheral visual field respectively.According to correlative study, human eye retina's central field of vision district accounts for human eye retina's 1/3.The glasses of existing zonal control central vision and peripheral visual acuity are not accurately considered to make the area ratio that district and periphery out of focus control zone are corrected by frame eyeglasses rear center, therefore can not accurate corresponding amphiblestroid correlation function district, do not consider that lens periphery light refraction that picture frame periphery printing opacity causes is on the impact of out of focus control effects, can not reach best near-sighted control effect effect yet.Prior art selects for the area of rectification district, center and periphery out of focus control zone and ratio does not still have clear and definite standard, the eyeglass total area size of the frame eyeglasses that applicable teenager wears is all in certain limited field, the area that central vision corrects district is too small, then the visual field is not enough, impact is worn, its area is excessive, then can not ensure that eyeglass has enough periphery out of focus control areas, not have optimum efficiency.

Further technical scheme is, the optical centre of described eyeglass is on picture frame geometric center, and difference in height is more than or equal to 0mm and is less than or equal to 3mm.
Further technical scheme is, described eyeglass central optical zone and the junction of lens periphery Optical Region are gradually Zoom structure or notch cuttype Zoom structure.
Further technical scheme is, the preferred ratio of the area C of the area B lens periphery Optical Region of described eyeglass central optical zone is B/C=0.5.
Further technical scheme is also, the frame of described picture frame is full frame, and color is lighttight dark color.
The beneficial effect adopting technique scheme to produce is:
The utility model eyeglass central optical zone is prepared as concavees lens, provides clear sharp keen central vision.According to correlative study result, the area ratio of retinal centre macular area and the non-macular area of periphery is about about 1/2, 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, the space utilization for eyeglass is more scientific and reasonable.The optical centre that mirror is deceived overlaps with the geometric center of mirror holder or higher than mirror holder geometric center, the optical centre of eyeglass can be allowed when wearing more to mate pupil center.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.Therefore the utility model has better myopia progression control effects compared to existing technology, and the teenager being applicable to myopia wears.
