Abstract
The utility model relates to an optical lens, in particular to a lens for prevention, correction and treatment of myopia, which comprises a main lens and a sub-lens. The main lens adopts a concave lens, and the sub-lens adopts a triple prism. The lens is characterized in that the sub-lens is arranged on the concave surface of the main lens, is integrated with the main lens, and is circular or is provided with a square upper part and a circular lower part. Since the triple prism is arranged on the concave surface of the concave lens in the structure of the lens for treatment of the myopia, the processing of the existing light diffusion surface through a cylindrical diamond grinding wheel is facilitated for production of the lens, the occurrence rate of defective work pieces is reduced, the cost of mass production is decreased, and good use effect is achieved. Moreover, the lens is convenient and easy to use in long-distance and short-distance viewing.
Description
One, technical field:
The utility model is a kind of optical mirror slip, particularly a kind ofly is used to prevent the bathomorphic eyeglass of corrective therapy.
Two, background technology:
Have a kind of in the prior art by wearing the method for convex lens eyeglass treatment adolescent myopia, its principle is to force eye's lens to be shunk to the opposite direction of myopia by the convex lens imaging, thereby reach therapeutic purposes, Chinese patent discloses the bathomorphic eyeglass of treatment of several employing concavees lens and prism combination, the lens structure of these technical schemes all is that primary mirror is common concave lens, is suitable for seeing correcting defects of vision when far away; See light substitutes eyes by sub-mirror when near and regulate, can prevent that myopia from deepening, but because structural design is unreasonable, its result of treatment is not ideal enough, and wherein prism is arranged on the convex surface of concavees lens more, by existing optics process equipment, the manufacturing process cost is higher, and difficulty of processing is big.
Three, summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of result of use obvious, handling ease, the bathomorphic eyeglass of treatment that cost is relatively low.
Technical scheme:
The bathomorphic eyeglass of a kind of treatment comprises primary mirror sheet and sub-eyeglass, and the primary mirror sheet is concavees lens, and sub-eyeglass is a prism, it is characterized in that: described sub-eyeglass is positioned at the concave surface of primary mirror sheet, and sub-eyeglass and primary mirror sheet are structure as a whole.
Described sub-eyeglass is circular.
Described sub-eyeglass is a square top and round bottom shape.
The beneficial effects of the utility model:
1, the bathomorphic eyeglass of treatment of the present utility model is arranged at the concave surface of concavees lens with prism, has made things convenient for existing astigmatic face to adopt tubular diamond-impregnated wheel machining lens, has reduced the occurrence rate of inferior workpiece, reduces mass production cost;
2, the bathomorphic eyeglass of treatment of the present utility model is arranged at the concave surface of concavees lens with prism, and result of use is good, and is convenient easy-to-use when watching at a distance and closely watch.
