Abstract
The fact that the conventional spectacles for myopia can not correct peripheral defocus of retina is the main cause increasing the degree of myopia. The utility model provides double-layered spectacles for correcting peripheral defocus of retina; the double-layered spectacles comprise main spectacles and additional spectacles; the central optic zone of each main lens is designed to be minus 0.50 DS to minus 7.00 DS, and the peripheral optic zone of the main lens adopts a plano lens; and the central optic zone of an additional lens adopts a plano lens or a lens with a round notch, and the peripheral optic zone of each additional lens is designed to be plus 0.50 DS to plus 2.00 DS. The double-layered spectacles for correcting peripheral defocus of retina has the advantages as follows: the main spectacles are worn to correct the center defocus of myopia and improve the distant vision; the central optic zones of the lenses are 15 mm to 45 mm in diameter, so that requirement of visual field in normal life can be met; and convex lenses at the peripheries of the lenses can correct the peripheral huperopic defocus of retina, so that myopic eye can be prevented effectively and the increasing of degree of myopia can be controlled.
Description
Technical field
The utility model relates to a kind of myopia correcting spectacle lens, more particularly, relates to a kind of Two-layer spectacle of correcting the retinal periphery out of focus.
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 peripheral position retina, be called out of focus behind the retinal periphery optics, be also referred to as retinal periphery long sight out of focus (hyperopic defocus); Focus is dropped on the former of peripheral position retina, be called out of focus before the retinal periphery optics, be also referred to as retinal periphery myopia out of focus (myopicdefocus).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 thinks that near work makes object focus in retina rear, peripheral position over a long time, forms retinal periphery long sight out of focus, disturbs the shape of eyes to feel, induce eyeball to prolong backward, thereby causes myopia or increase the myopia number of degrees.Research thinks that also existing myopia eyeglass 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 increases constantly.Correct retinal periphery long sight out of focus or manually form retinal periphery myopia out of focus, can effectively prevent myopia to take place or the increase of the control myopia number of degrees.At present existing myopia rectification, prevention and treatment problem are still the great technical barrier of international medical community.
