Abstract
Ophthalmic lenses are described herein. An example ophthalmic lens may comprise a first surface. The example ophthalmic lens may comprise a second surface disposed opposite the first surface and defining a volume of lens material therebetween. A thickness profile of the volume of lens material may be derived from one or more eyelid profiles such that a thickness gradient of the volume of lens material is oriented to be substantially orthogonal to a target eyelid margin shape.
Claims25
A method comprising:
- determining one or more eyelid profiles associated with one or more eyelids;
- determining, based on the one or more eyelid profiles, a target eyelid margin shape;
- forming, based on at least the target eyelid margin shape, an ophthalmic lens comprising a first surface and a second surface disposed opposite the first surface and defining a volume of lens material therebetween,
- wherein a thickness profile of the volume of lens material is derived from the one or more eyelid profiles such that a thickness gradient of at least a portion of the volume of lens material is oriented to be substantially orthogonal to the target eyelid margin shape.
