Abstract

The present invention relates to a contact lens formed from components including (i) at least one silicone component (ii) at least one low molecular weight polyamide having a weight average molecular weight of less than 200 ,000, and (iii) at least one high molecular weight polyamide having a weight average molecular weight of greater than 200 ,000, wherein the low molecular weight polyamide does not contain a reactive group.
