Abstract
Short-sight progressive defocus correcting glasses belong to health care glasses. The prior-art short-sight glasses can not correct hyperopic defocus at the periphery of a retina, and therefore diopter development of myopic eye can not be controlled. The glasses provided by the utility model are composed of a glasses frame, glass legs and lens. The utility model is technically characterized in that: each lens is prepared to be divided to a central defocus area, a defocus middle area and a peripheral defocus area; or a near viewing area is prepared at the peripheral part of a lens below the central defocus area; the central defocus area of the lens corrects the central defocus of the retina; the near viewing area of the lens alleviates near viewing adjustment load and convergence power of the eye; and the peripheral defocus area corrects the hyperopic defocus at the periphery of a retina, and the defocus middle area of the lens reduces diopter difference jump phenomenon between the central defocus area of the lens and the peripheral defocus area. The glasses are particularly suitable for wearing by the teenagers, can effectively correct myopic eye and controls diopter development of myopic eye.
Description
Technical field
The utility model relates to a kind of glasses for myoporthosis, specifically, relate to the progressive out of focus correcting spectacle lens of a kind of myopia, more particularly, correct retinal centre out of focus, peripheral out of focus district and correct refractive diopter ladder difference jump phenomena, near reading range that retinal periphery out of focus, out of focus mesozone reduce central out of focus district and peripheral out of focus district and alleviate and look nearly an adjusting load and a convergence power in the eyeglass of this glasses central authorities out of focus district.
Background technology
Eyeball has emmetropization active adjustment process, relies on focusing growth, especially the optics out of focus at retinal periphery position (optical defocus) of vision.The optics out of focus at retinal periphery position drops on before and after the retina according to focus, according to the ophthalmic dioptrics notion, with the latter that focus drops on the retinal periphery position, is called retinal periphery long sight out of focus (hyperopic defocus); Focus is dropped on the former of retinal periphery position, be called retinal periphery myopia out of focus (myopic defocus).Retinal periphery long sight out of focus induces eyeball to grow backward, forms myopia or promotes the myopia number of degrees to increase.Retinal periphery myopia out of focus delays eyeball and grows backward, and the control myopia number of degrees increase.Modern medicine study is thought, near work makes object focus in rear, retinal periphery position over a long time, forms retinal periphery long sight out of focus, disturb the shape of eyes to feel, induce eyeball to prolong backward, thereby cause myopia or promote the myopia number of degrees to increase.Research thinks that also existing monochromatic light concave lens, two light concave lens, progressive additional concave lens and compound prism concave lens only can be corrected the retinal centre out of focus, can not correct retinal periphery long sight out of focus, so the myopia number of degrees increase constantly.Correct retinal periphery long sight out of focus or manually form retinal periphery myopia out of focus, can effectively control or slow down the myopia number of degrees increases.
