Abstract
Disclosed herein is a contact lens comprising a lenticular in a 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 allows the contact lens to translate upwards in downgaze and maintain rotational stability. By having rotational stability and translation, a contact lens having a progressive addition optic zone is provided.
Claims32
A contact lens comprising:
- a superior portion of the contact lens;
- an inferior portion of the contact lens;
- a progressive addition optical zone;
- and
- 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 allows the contact lens to translate upwards in downgaze, and
- wherein Zernike coefficients are developed for the optical zone, and said Zernike coefficients are used to determine surface curvatures, spherical powers, and astigmatic powers of the optical zone.
