    Abstract: The method involves preparing a transparent print primer comprising a binder constituted by a colloidal silicon dioxide for increasing diffusion of ink in an aqueous dispersion of polymer, and an absorbing polymer for increasing absorption of ink in the dispersion. The primer is deposited on a face of a plastic substrate of ophthalmic lens for forming a film. The primer is dried and printed using an inkjet printer, and the ink is dried. An independent claim is also included for an ophthalmic lens colored by a coloring method.
