Claims15
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
- said surface further comprises one concentric annular ring having non-cylinder near 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
- said surface further comprises one concentric annular ring having non-cylinder near spherical optical power.
A method of designing a lens for the correction of astigmatic presbyopes comprising designing 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
- said surface further comprises one concentric annular ring having non-cylinder near spherical optical power.
