Abstract

Contact lenses incorporate high plus or add power profiles that at least one of slow, retard or preventing myopia progression and minimize halo effect. The lens includes a center zone with a negative power for myopic vision correction; and at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile that increases from an outer margin of the center zone to a positive power within the at least one treatment zone of greater than +5.00 D.

Claims (8)

1. An ophthalmic lens configured for at least one of slowing, retarding or preventing myopia progression and minimizing halo effect, the ophthalmic lens to be worn on an eye of a patient for correcting a refractive error comprising:

a center zone with a negative power for myopic vision correction while worn on eye; and

at least one treatment zone surrounding the center zone, said at least one treatment zone having a power profile that only increases continuously and gradually from an outer margin of the center zone, corresponding to a radius of 2 mm, to a positive power within at an outer margin of the at least one treatment zone of greater than +5.0 D at a distance of between 3.0 mm and 4.5 mm from a center of the ophthalmic lens and then remains constant to a margin of an optic zone, wherein the power profile is tailorable to a pupil size of a patient, wherein the outer margin of the center zone has a radius of 2 mm from a center of the ophthalmic lens and the at least one treatment zone has an outer margin of between 3.0 mm to 4.5 mm from the center of the ophthalmic lens.

2. The ophthalmic lens according to claim 1 , where the at least one treatment zone has a positive power from about +5.0 D to about +15 D.

3. The ophthalmic lens according to claim 1 , wherein the at least one treatment zone has an outer margin at about 4.5 mm from a center of the lens.

4. The ophthalmic lens according to claim 1 , wherein a halo effect at a black/white edge is minimized.

5. The ophthalmic lens according to claim 1 , wherein the ophthalmic lenses comprises a contact lens.

6. The ophthalmic according to claim 1 , further comprising one or more stabilization mechanisms.
