Description
Technical field
The utility model relates to the optometric technology field, specifically, relates to a kind of eyeglass that overlays that sticks on correction of myopia on spectacle lenses or farsightedness retinal peripheral defocusing.
Background technology
Periphery out of focus theory is thought: conventional myopic eye spectacle lenses central part is identical dioptric character or refractive diopter concace mirror lens with peripheral position, central part is when correcting the retinal centre out of focus, the periphery position increases retinal periphery long sight out of focus, induces eyeball to grow backward, promote the myopia number of degrees to increase.Tradition farsightedness spectacle lenses central part is identical dioptric character or refractive diopter convex lens sheet with peripheral position, central part is when correcting the retinal centre out of focus, the periphery position increases retinal periphery Myopia out of focus, stop eyeball and grow backward, delay eyeball emmetropization process, this is the glasses sources paathogenic factor of conventional frame lens, the root that conventional myopic glasses or spectacles for long sight are worn worse and worse.
Periphery out of focus lens is that eyeglass central part and peripheral position are designed to be not identical dioptric character or different refractive diopter eyeglass, and peripheral position is designed to as correcting the eyeglass of retinal periphery long sight out of focus or Myopia out of focus.Periphery out of focus lens is a revolution of spectacles, and conventional myopic eye spectacle lenses faces update trend.Existing peripheral out of focus lens technology is: China Patent No.: 2008801159183, patent name: ophthalmic lens element, disclose a kind of myopia periphery out of focus lens of horizontal ellipse central optical zone, this technology is released first peripheral out of focus spectacle lenses of the whole world by Ka Er Zeiss optics, and commodity Zeiss by name becomes permanently happy (myovision) lens; Another China Patent No.: 2006800441239, patent name: be used for the eyeglass of myopia correction, disclose a kind of myopia periphery out of focus lens of positive circular central optical zone.Above-mentioned two patented technologies become permanently happy lens to make outstanding contribution to mankind children and juvenile shortsightedness with Zeiss, but, above-mentioned two patented technologies have been ignored eye and have been looked far away and look nearly " vertical field of view " scope when design, the preceding paragraph patented technology is horizontal oval-shaped " horizontal field of view ", and consequent patented technology is just as " horizontal field of view " of glaucoma " tubular visual field ".Eye is mainly look far away and look near, and especially student's eyes of upper class hour move up and down to complete and look at a distance blackboard and look nearby books or write.The design of progressive additional lens is also " vertically looking passage ", also proves central optical zone and should be designed to " vertical field of view ".Periphery out of focus lens will meet two heavy indexs when design: the one, enough large regional retinal centre out of focus of correcting are arranged, satisfying specifically eye looks far away and looks near field range, i.e. " vertical field of view " scope, another is to have enough large zone correct retinal peripheral defocusing.
Overlay eyeglass (press-on lens) and be the flexible ametropia lens of the film-form that sticks on the frame-generic lens, overlay eyeglass and overlay concace mirror lens, overlay three kinds of convex lens sheet and pressing triple prism sheets.The concace mirror lens that overlays that U.S. 3m company sells has 14 power lens, and overlaying convex lens sheet has 16 power lens, and the pressing triple prism sheet has 18 power lens.

4, central optical zone prepares the not identical convex lens sheet of radius-of-curvature with peripheral Optical Region, and the central optical zone refractive diopter is greater than the eyeglass that overlays of peripheral Optical Region refractive diopter, between the poor reduction of peripheral Optical Region refractive diopter 1.00DS～3.00DS.
Bonding method: this eyeglass that overlays is according to clinical rectification purpose difference, be pasted on spectacle lenses in individual layer spectacle-frame or Two-layer spectacle primary frame or Two-layer spectacle supplementary frame overlaying eyeglass, spectacle lenses can be concace mirror lens, convex lens sheet or plano lens.
The eyeglass principle: the utility model is to utilize to overlay eyeglass and have softness, transparent, dioptric and paste functionality, stick on spectacle lenses, by overlaying the refractive diopter combination principle of eyeglass and spectacle lenses, create a kind of novel combination type periphery out of focus glasses.This vertical diameter line that overlays the eyeglass central optical zone is longer than horizontal radial line, more meets eye and looks far away and look near physiological optics visual field needs.This lens periphery Optical Region that overlays designs at least from optical centre (OC) along upside radial line (RU), nasal side radial line (RN), temporo side radial line (RT) 15mm～20mm place, at least occupy the zone, 270 °, position angle of circumference at lens periphery position, convex lens sheet, concace mirror lens or the plano lens of retinal peripheral defocusing corrected in preparation, still can effectively correct retinal peripheral defocusing.This " vertical field of view " central optical zone overlay eyeglass, both provided and enough looked greatly a myopia scope, satisfying again has that enough large to correct retinal peripheral defocusing regional, central optical zone and peripheral Optical Region principle of mutual when having accomplished design.The peripheral out of focus of " vertical field of view " of the present utility model central optical zone overlays eyeglass, has overcome " horizontal field of view " of existing peripheral out of focus spectacle lenses or the technological deficiency that has tunnel vision of " tubulose visual field ", and a kind of novel eyeglass that overlays is provided again.This eyeglass that overlays, having kept the conventional frame lens looks rectification retinal centre out of focus far away, improves distant vision, the broad advantage in the eyeglass visual field, overlay lens periphery position rectification retinal peripheral defocusing, the retarding myopia eyeball increases, promote long sight eyeball emmetropization, effectively prevent and treat myopia or farsightedness.
Usable range: this full out of focus overlays eyeglass, and main adaptation population is that between 6 years old～18 years old, children and juvenile shortsightedness person or farsightedness are worn, and also adapts to the age to develop at a too fast speed or hyperpresbyopia eye person greater than 18 years old myopia number of degrees.
