FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, particularly to ophthalmology, namely: to antibacterial lenses containing metals, as well as to methods for producing them. The method for producing an antibacterial lens containing a metal salt involves the stages: (a) preparation of a hard lens by a salt precursor, as well as (b) preparation of the lens produced at the stage (a) by a disperse additive specified in a group consisting of polyvinylpyrrolidone, polyvinyl alcohol, glycerol and polyethylene oxide, and a metal-containing agent specified in a group consisting of silver tetrafluoroborate, silver sulphate, zinc acetate, zinc sulphate, copper acetate, copper sulphate, silver nitrate, manganese sulphide, zinc oxide, zinc sulphide, copper sulphide, copper phosphate, silver nitrate, silver sulphate, silver iodate, silver carbonate, silver phosphate, silver sulphide, silver chloride, silver chloride, silver bromide, silver iodide and silver oxide. The other method for producing involves the stages (a) of preparation of a hard lens by a metal-containing agent, and a disperse agent, (b) preparation of the lens prepared at the stage (a) by a salt precursor. The antibacterial lens containing the metal salt is produced by said methods.

EFFECT: group of inventions provides producing the lenses with a decreased degree of opacity.
