1. An ophthalmic lens, comprising:
at least one polymerized lens substrate including at least one thermoset monomer;
a functional component including at least one thermoplastic layer, a surface of the at least one thermoplastic layer facing the polymerized lens substrate; and
a primer coating deposited onto the surface of the at least one thermoplastic layer facing the polymerized lens substrate;
wherein the primer coating includes
at least one first reactive monomer including a reactive acrylic group,
at least one second reactive monomer, and
at least one photoactive catalyst;
wherein the at least one first reactive monomer of the primer coating is an acrylic monomer or a mixture of acrylic monomers;
wherein the at least one first reactive monomer of the primer coating is capable of reacting with the lens substrate monomer; and
wherein the at least one second reactive monomer of the primer coating is an alkoxysilane.
