Abstract
A ring covering type corneal contact lens capable of changing the diameter of a transparent area under different intensity rays relates to a corneal contact lens, and aims to solve the problem that the diameter of the central pin hole of the prior pin hole imaging contact lens is inadaptable to different human eye's treatment to light reflection. The light-proof area in the utility model adopts aring-shaped structure and is arranged on the outer side of a transparent area, and a color change area adopts a ring-shaped structure and is arranged between the transparent area and the light-proof area. The utility model ensures that the color change area is dark colored under strong light if the diameter of a pupilla is the same as that of the transparent area, thereby having no influences on the pupilla, and even the color change area shallows or is colorless under dark light, the influences on the pupilla is still small. If the diameter of the pupilla is larger than that of the transparent area, the color change area is dark colored under strong light, the transparent area plays a certain restriction on slackness of pupilla ciliary muscle, and even the color change area shallows or iscolorless under dark light, the utility model is adaptable to the adjustment to large pupilla ciliaris.
Description
Technical field
The utility model relates to a kind of contact lens (contact lenses).
Background technology
China Patent No. is ZL98236277.3, Granted publication day is on September 8th, 1999, Granted publication number is CN2337581Y, name is called the utility model patent of " the pinhole imaging system contact lenses that are used for the treatment of pseudo-myopia ", its disclosed pinhole imaging system contact lenses itself can not be treated pseudo-myopia, but after the patient has used the ciliary muscle relaxation agent to carry out " mydriasis ", put on the pinhole imaging system contact lenses and be used for overcoming the bad light reaction that mydriasis causes, as blurred vision, photophobia etc., put on this pinhole imaging system contact lenses and when cooperating ciliary muscle relaxation agent treatment pseudo-myopia, do not influence life, study and work is a kind of instrument of supplemental treatment pseudo-myopia.The center of these pinhole imaging system contact lenses has the aperture that a diameter is 1～4mm, described aperture is used to retrain the degree of relaxation of ciliary muscle, but the pupil size of human eye is different (referring under identical light intensity condition), generally believe according to ophthalmology educational circles: generally (Chinese patent application number is 200780016489.X to the pupil diameter of human eye between 2.5～4.0mm, open day is on May 20th, 2009, publication number is CN101438203A, the patent application document that name is called the multifocal contact lenses of pupil apodization " utilize design " discloses a kind of dimensional measurement data of pupil, they think that effective pupil diameter is between 1.93～4.94mm, see the disclosure instructions the 7th page), therefore, the central small hole of pinhole imaging system contact lenses is made the demand that much diameters could adapt to the pupil size of different human eyes, always can not make tens twenties specifications, increase cost on the one hand, be not easy to management, also can make troubles on the other hand to joining mirror.
The utility model content
The purpose of this utility model is to fix for the central small hole diameter that solves existing pinhole imaging system contact lenses, the pupil that can not adapt to different human eyes is treated the problem of light reflection, and a kind of following ring screening type contact lens that changes the clear area diameter of light of varying strength is provided.The utility model comprises eyeglass, eyeglass is made up of lightproof area, color change interval and transparent region, transparent region is arranged on the central area of eyeglass, the diameter of transparent region is 1.8～3.2mm, lightproof area is the loop configuration and the outside that is arranged on transparent region, color change interval be loop configuration and be arranged on transparent region and lightproof area between, the internal diameter of color change interval is 1.8～3.2mm, the external diameter of color change interval is 4.8～5mm.
The beneficial effects of the utility model: contact lens of the present utility model, between the transparent region of eyeglass and lightproof area, be provided with color change interval, the diameter of color change interval is within the scope of the pupil diameter size of human eye.Wear contact lens of the present utility model, if the diameter of pupil and transparent region diameter is big or small identical, color change interval is dark under high light, to not influence of pupil, though it is color change interval shoals or be colourless under half-light, at this moment, also little to the influence of pupil because light is darker.If the diameter of pupil is greater than the diameter of transparent region, color change interval is dark under high light, though color change interval shoals or be colourless under half-light, at this moment can adapt to the vision requirement under high light and the half-light.The utility model not only can adapt to the difference of the pupil diameter size of human eye, and can correct incorrect reading and writing posture after cooperating the ciliary muscle relaxation agent, treats pseudo-myopia, alleviates true and false mixed myopia, limits true myopia.
