Claims25
An ophthalmic lens comprising a convex surface and a concave surface
- wherein
- one of said surfaces comprises a center zone having distance spherical and cylinder optical power and
- at least one concentric annular ring having optical power selected from one member of the group consisting of
- (a) a distance spherical and cylinder optical power,
- (b) a near optical power, and
- (c) a distance spherical optical power.
A method for correcting the vision of an astigmatic presbyope comprising the step of providing a pair of ophthalmic lenses where each ophthalmic lens comprises a convex surface and a concave surface
- wherein
- one of said surfaces comprises a center zone having distance spherical and cylinder optical power and
- at least one concentric annular ring having optical power selected from one member of the group consisting of
- (a) a distance spherical and cylinder optical power,
- (b) a near optical power, and
