High plus treatment zone lens design and method for preventing and/or slowing myopia progression
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.
1. A method for at least one of slowing, retarding or preventing myopia progression of an eye by:
providing an ophthalmic lens having a center zone with a negative power for myopic vision correction and at least one treatment zone surrounding the center zone, said at least one treatment zone having a power profile that increases continuously and smoothly from an outer margin of the center zone, corresponding to a radius of 2 mm, to a positive power within the at least one treatment zone of greater than +5.00 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; thereby altering growth of the eye.
2. The method according to claim 1 , wherein a halo effect at a black/white edge is minimized.
3. The method according to claim 1 , wherein the ophthalmic lens is configured as a contact lens.
4. The method according to claim 1 , further comprising adding one or more stabilization mechanisms to the lens.
