The invention provides ophthalmic lenses useful in preventing myopia progression. The lenses of the invention provide substantially constant distance vision power zone in the center of the optic zone surrounded by a zone that provides positive longitudinal spherical aberration.
Claims18
An ophthalmic lens, comprising an optic zone comprising a central zone having substantially constant distance vision power and at least a first annular zone concentric with the central zone and having positive longitudinal spherical aberration.
An contact lens, comprising an optic zone comprising a central zone having substantially constant distance vision power and at least a first annular zone concentric with the central zone and having positive longitudinal spherical aberration, wherein the distance vision power is overcorrected by about 0.25 to about 1.00 diopters.
An ophthalmic lens, comprising an optic zone having a substantially constant distance vision power at the centermost portion of the optic zone and at least a first peripheral region to the distance vision power having positive longitudinal spherical aberration.
A method of preventing myopia, comprising the step of providing an ophthalmic lens comprising an optic zone comprising a central zone having substantially constant distance vision power and at least a first annular zone concentric with the central zone and having positive longitudinal spherical aberration.
A method of preventing myopia, comprising the step of providing an contact lens, comprising an optic zone comprising a central zone having substantially constant distance vision power and at least a first annular zone concentric with the central zone and having positive longitudinal spherical aberration, wherein the distance vision power is overcorrected by about 0.25 to about 1.00 diopters.
