Abstract
Contact lenses incorporating asymmetric radial power profiles that increase the radial dioptric power from the center to the margin of the optical zone of the lenses may be utilized to prevent and/or slow myopia progression. The power profiles vary along different meridians.
Claims12
An ophthalmic lens for at least one of slowing, retarding or preventing myopia progression, the ophthalmic lens comprising:
- an optic zone configured with a positive asymmetric aberration for creating a physiological effect on the eye, the positive asymmetric aberration including asymmetric radial power profiles with increasing dioptric power from a center to a margin of the optic zone and wherein the asymmetric radial power profiles are variable along different radial meridians;
- and
- a peripheral zone surrounding the optic zone.
A method for at least one of slowing, retarding or preventing myopia progression by altering the focus of the eye by a direction and degree to alter the growth of the eye, the method comprising introducing asymmetric radial power profiles with increasing dioptric power from a center to a margin of an optical zone of an ophthalmic lens and varying the asymmetric radial power profiles along different radial meridians.
