Ophthalmic lens with an optically non-coaxial zone for myopia control

1. An ophthalmic lens for at least one of slowing, retarding or preventing myopia progression of a wearer, the ophthalmic lens comprising:

a center zone centered around an optical axis, said center zone having a negative power for myopic vision correction of said wearer; and

at least one treatment zone surrounding the center zone and disposed radially outward from the center zone, and centered around the optical axis, the at least one treatment zone having an ADD power relative to the center zone,

wherein the at least one treatment zone has a surface shape derived from a portion of a torus wherein the surface shape is configured to direct light passing therethrough to form a continuous focal ring positioned in front of the retina of the wearer and around the optical axis, and wherein the surface shape of the at least one treatment zone forms a continuous surface with the center zone.

2. The ophthalmic lens of claim 1 , wherein the portion of the generally toroidal shape may be derived from a torus (e.g., a spheroidal torus), after making a slice in the shape of the surface of a right circular cone through the surface of the spheroidal torus wherein the principal axis of the cone is coincident with the axis of rotation about which the torus is generated.

3. The ophthalmic lens according to claim 1 , wherein the at least one treatment zone is configured to minimize generation of a focal point behind a retinal plane of the eye of a wearer.

4. The ophthalmic lens according to claim 1 , further comprising a transition zone disposed between then center zone and the at least one treatment zone such that the at least one treatment zone, the transition zone, and the center zone form a continuous surface.

5. The ophthalmic lens according to claim 1 , wherein the at least one treatment zone comprises an ADD power relative to the myopia correction power of greater than +5.00 D.

6. The ophthalmic lens according to claim 1 , wherein the at least one treatment zone comprises an optical power from about −10.00 D to about +15.00 D.

7. The ophthalmic lens according to claim 1 , wherein a diameter of the center zone is about 2 mm to about 7 mm.

8. 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.

9. The ophthalmic lens according to claim 1 , wherein a halo effect is minimized.

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

11. The ophthalmic lens according to claim 1 , wherein the ophthalmic lens comprises a spectacle lens.

12. The ophthalmic lens according to claim 1 , wherein the ophthalmic lens comprises an intraocular lens, a corneal inlay, or a corneal onlay.

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

14. The ophthalmic lens according to claim 1 , comprising:

wherein the at least one treatment zone further comprises a tilt angle configured to direct an innermost ray relative to a cross section of the treatment zone to cross the optical axis at a point that is at or anterior to a retinal plane of a wearer of the ophthalmic lens.

15. The ophthalmic lens according to claim 14 , wherein the tilt angle is configured to direct the innermost ray to cross the optical axis at a point between the retinal plane and a point on the optical axis that represents a coincident point focus of the treatment zone.

16. The ophthalmic lens according to claim 14 , wherein the tilt angle is dependent upon an optical power of the treatment zone.
