Abstract
Disclosed herein is a contact lens. Some disclosed embodiments comprise a lenticular aspect. In some instances the lenticular aspect varies in at least one of thickness, distance from the edge of the contact lens, or lenticular height along its length. In one aspect, a superior portion of the lenticular aspect attaches to an upper eyelid of a wearer by at least a portion of the lenticular aspect interacting with an upper tarsal plate of the upper eyelid of a wearer.
Claims24
A contact lens comprising:
- a superior portion of the contact lens;
- an inferior portion of the contact lens;
- a lens portion;
- an edge extending a circumference of the contact lens;
- and
- a lenticular aspect having a length and extending the circumference of the contact lens, wherein the lenticular aspect has dimensions of a thickness, a distance from the edge, and a lenticular height, wherein each of the dimensions of the lenticular aspect vary along the length of the lenticular aspect;
- and
- wherein at least a portion of the lenticular aspect is shaped to interact with an upper tarsal plate of an upper eyelid of a wearer, said interaction translating the contact lens upwards in a downgaze of the wearer or holding the contact lens in an upwards position as a wearer's eye moves downwards behind the contact lens.
