A narrow profile, glare reducing, refractive mono-focal intraocular lens is described that comprises an optic having an anterior surface and a posterior surface and an optical axis. One of the anterior and posterior surfaces is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power that is preferably outside the −5 to +5 diopter range. A transition zone between the two imaging zones preferably has a continuously variable surface curvature that reduces both indirect glare (caused by light refraction) and direct glare (caused by light diffraction) in an individual's eye in which the intraocular lens is implanted. The transition zone surface may alternatively be continuously curved or variably curved to reduce direct glare and indirect glare, respectively. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye.
