A multifocal lens device (10) comprising: a lens body (12) that is formed with a plurality of concentric annular zones (14) having surfaces separated by inclined sections (16) having surfaces, wherein said surfaces of the aforementioned concentric zones (14) effect both the diffraction and the refraction of the incident light, while said surfaces of said sections (16) are adequately empty of any diffractive or refractive power; and wherein at least one zone (24) of said plurality of concentric zones (14) has a diffraction pattern formed on a respective surface (24), such that a diffractive power of said surface (24) gradually decreases through said surface (24).
