Abstract
The purpose of the present invention is to provide: a functional polymer gel which is able to be practically used as an ocular lens having excellent transparency and mechanical strength by uniformly dispersing organic nanotubes in a polymer gel without the formation of agglomerates of the organic nanotubes in the case where the organic nanotubes are complexed into the polymer gel; and a method for producing this functional polymer gel. The above-mentioned purpose is achieved by: a functional polymer gel which is characterized by containing organic nanotubes and having a light transmittance of 80% or more; and a method for producing this functional polymer gel.
