Abstract:
Provided is an ophthalmic lens, from which the elution of a coloring agent can be prevented effectively even when the ophthalmic lens is produced by polymerizing a polymerizable composition containing the coloring agent or when the ophthalmic lens is produced by printing an ink composition containing the coloring agent on a lens precursor by a known printing technique such as an inkjet printing method to allow the coloring agent to penetrate into the lens precursor. The ophthalmic lens is produced using a non-polymerizable compound represented by a specific structural formula as a coloring agent.
