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.

Abstract: The present invention is related to a contact lens for correcting severe spherical aberration. The contact lens of the invention comprises an anterior surface having a first optical zone and an opposite posterior surface having a second optical zone. The first optical zone is defined by a mathematical function including a conic term and at least one 4th or higher order mathematic term. The first optical zone, in combination with the second optical zone, provides a power profile in which the optical power of the lens decreases outwardly from the optical axis to the outer periphery such that the optical power at a 6 mm diameter is from about 1 to 5 diopters smaller than a manifest refractive power for an eye. The present invention also provides a series of contact lenses and a method for making contact lenses of the invention.
