Abstract
Disclosed herein is a contact lens comprising a an optic zone formed on a lens portion of the contact lens, the optic zone having a single power or multiple powers, and one or more transition zones between the one or more of the powers. The contact lens can also include a rear surface configured to center the contact lens on the cornea of the patient. In some instances, the contact lens may include a lenticular located in the superior portion of the contact lens, wherein the contact lens attaches to an upper eyelid of a wearer by the lenticular interacting with an upper tarsal plate of the upper eyelid of a wearer, said interaction causing the contact lens to translate upwards in downgaze.
Claims31
A contact lens comprising:
- a superior portion of the contact lens;
- an inferior portion of the contact lens;
- a lens portion;
- a lenticular located in the superior portion of the contact lens, wherein the contact lens attaches to an upper eyelid of a wearer by the lenticular interacting with an upper tarsal plate of the upper eyelid of a wearer, said interaction causing the contact lens to translate upwards in downgaze;
- and
- an optic zone formed on the lens portion of the contact lens, the optic zone having multiple powers, and one or more transition zones between one or more of the powers.

A method of making a contact lens comprising:
- forming a lenticular located in a superior portion of the contact lens, wherein the lenticular is formed to attach to an upper eyelid of a wearer by the lenticular interacting with an upper tarsal plate of the upper eyelid of a wearer, said interaction causing the contact lens to translate upwards in downgaze;
- and
- forming an optic zone on a lens portion of the contact lens, the optic zone having multiple powers, and a transition zone between one or more of the powers.

A contact lens comprising:
- a superior portion of the contact lens;
- an inferior portion of the contact lens;
- a lens portion;
- and
- an optic zone formed on the lens portion of the contact lens, the optic zone having multiple powers, and a transition zone between one or more of the powers,
- wherein the multiple powers of the optic zone comprise a first optical power, a second optical power, and an optional third optical power,
- wherein the first optical power comprises a distance optical region, the second optical power comprises a near optical region, and the optional third optical power comprises an intermediate or progressive addition optical region, and
- wherein the distance optical region comprises a minus-shaped distance (thicker edge and thinner center) optical zone and the near optical region, and/or the intermediate and/or progressive addition optical region comprises an optical axis that is rotated downward and an optical axis of the distance optical region is also rotated downward.
