Abstract
An ophthalmic lens includes an optical zone having a center and a spaced-apart periphery. The optical zone has a first corrective power range in a first region and a second corrective power range in an annular region surrounding the first optical zone. The second corrective power is corrective of spherical aberration of an eye. The optical zone has a power profile that gradually changes from the first corrective power to the second corrective power. A central progressive zone that provides intermediate vision correction may be applied to a central region of the lens. The progressive zone has a diameter that is less than or equal to the diameter of an aperture of a pupil when subjected to bright light.
