Abstract: The composite ophthalmic lens (1) comprises a first layer (2), at least 200 micrometers thick, forming a front part of said lens, of a first polymeric material of refractive index higher than or equal to 1.60 and having a front face (4) constituting a front optical surface S1, and a second layer (3), at least 200 micrometers thick, of a second polymeric material forming a rear part of said lens and having a rear face (6) constituting a rear optical surface S2, the interface (5) between these two layers constituting an optical surface S3 parallel to the rear optical surface S2.
