METHOD OF MANUFACTURE OF THE PLASTIC LENSES AND THE PLASTIC LENS Russian patent published in 2006 - IPC B29D11/00 G02B11/04 G02C7/04 C08G75/06 C08L81/04 

FIELD: medical industry; method of manufacture of the plastic lenses and the plastic lens.

SUBSTANCE: the invention is pertaining to the field of medical industry, in particular, to the method of manufacture of the plastic lenses, which may be used in the capacity of glasses plastic lenses. The method of manufacture of the plastic lens includes the phase of polymerization of the mixture (1) of the prepolymer produced by mixing and interaction of sulfur taken in the amount from 0.1 mass % up to 10 mass % counting upon the total amount of the mixture and containing the epithio-group compound, (2) of polyisocyanate compound and (3) polythiol compound. The invention also presents the lenses manufactured by the given method. The technical result of the invention is production of the plastic lenses with the high index of diffraction, the high Abbe number and the high mechanical strength.

EFFECT: the invention ensures production of the plastic lenses with the high index of diffraction, the high Abbe number and the high mechanical strength.
