Definitions
- the present invention relates to high refractive index plastic lenses. More specifically, the present invention relates to a plastic lens for an endoscope with a refractive index ( ⁇ ) of Z ⁇ or more. Background technology
- a plastic lens for an ophthalmoscope is manufactured by casting and polymerizing. These plastic lenses are lighter, safer and more dyeable than conventional inorganic glass lenses (Kraungara glass lenses). Although it is excellent in terms of chromaticity, it has a refractive index () of about / 0 and a refractive index of about /.S23, which is a conventional inorganic glass lens. Compared with the (Range glass lens), there is a drawback that the center thickness and the edge thickness are large, and in order to improve such a defect, a high bending strength is required.
- a high refractive index plastic is obtained by copolymerizing a monomer for producing a high refractive index polymer such as a CR-monomer.
- a method for obtaining the above has conventionally been known.
- the physical and chemical properties of the obtained polymer can be obtained not only by simply increasing the refractive index.
- O-Pensinol methacrylate Clear index is LS 0-J even in the i-system. It can be changed to about S ⁇ , but the surface hardness becomes much worse, and glass coating by vacuum deposition also becomes impossible. . Also, depending on the amount of the benzyl metal creature used, the product may be cloudy, which is not desirable for an ophthalmic lens. become
- the inventors of the present invention have made intensive studies to remedy the above-mentioned drawbacks, and as a result, have found that: In the specific composition region of the ternary copolymer of the plate, it was cloudy (above the refractive index / J " ⁇ ), and no striae was observed. As a lens for ophthalmic use, it was found that a high-refractive-index plastic lens with good physical and chemical properties could be obtained. Has been reached o
- the purpose of the present invention is to prevent the purpose of the present invention, and to provide a high refractive index (3 ⁇ 4 / or more) having no striae and excellent physical and chemical properties. It is to provide a plastic lens.
- the present invention is based on the following specifications: ethylene glycol, bisulfur carbonate, benzene methacrylate crelet, and jarino resolute. It relates to a high refractive index plastic lens, which is characterized by having a refractive index above / ⁇ ⁇ consisting of a copolymer of .
- the preferred amount of CR-used in the present invention is ⁇ heavy, and the preferred amount of benzylmethacrylate is ⁇ ⁇ 0 weight, The preferred use amount of gallary resin is 90 to 20 weight.
- Etc. is improved, but the refractive index becomes less than 3 ⁇ , and at the same time, the striae can be recognized in the lens as well as the striae. I don't like it as a lens. Below the weight, physical and chemical quality is poor, moldability is poor, and there is a problem in practicality. If the amount of benzylmethacrylate used exceeds ⁇ 0 weight, cloudiness and striae will be recognized, and the morphogenesis is abnormal. It is not good or bad. The usage of the jelly isolate rate is heavy. Beyond this, the physical and chemical properties are poor, and the moldability is poor, and
- a mixture of benzene methacrylate, garnet oleosolate, and a polymerization initiator is made of glass monolith and resin. It can be obtained by pouring into a mirror mold assembled by a gasket and hardening using means such as heating or UV irradiation. .
- the high refractive index plastic lens of the present invention is cloudy, has no striae, has good moldability, and simply has a high refractive index. This is different from the conventional plastic lens.
- the high refractive index plastic lenses of the present invention which are superior in all aspects of optical properties, chemical properties, physical properties and moldability, are specially formulated. It is also a preferred plastic lens for eyeglasses.
