The ophthalmic lens (1) further comprises a unique lens identification code which is arranged in the peripheral zone (3) of one of said front and rear surfaces. The unique lens identification code has the form of an N×M dot matrix (5) comprising N rows and M columns of matrix elements (50), and the N×M dot matrix (5) represents a binary code.
