LENS CONTAINING LOW-MOLECULAR AND HIGH-MOLECULAR WEIGHT POLYAMIDES Russian patent published in 2017 - IPC B29D11/00 G02B1/04 

FIELD: physics.

SUBSTANCE: method comprises dosed supply into the reaction mixture mould containing a silicone component, a low-molecular weight polyamide having no reactive group, having a weight-average molecular weight of less than 200,000, a high-molecular weight polyamide having a weight-average molecular weight of more than 200,000 and less than about 15 wt % of diluent, curing the reaction mixture inside the mould to form a contact lens, liquid-free removing the contact lens from the mould, and extracting the contact lens using aqueous solutions.

EFFECT: obtaining a contact lens with increased comfort and wettability.
