Abstract
Disclosed is a method, for example implemented by a computer, for determining the shape of a nose pad, to be part of an ophthalmic lens intended to be worn by a wearer, the method including: receiving lens shape data relating at least to the shape of an ophthalmic lens; receiving morphology data relating at least to the morphology of the nose of the wearer; and determining the shape of the nose pad intended to be part of the ophthalmic lens intended to be worn by the wearer based at least on the lens shape data and morphology data.

A method for determining a shape of a nose pad to be part of an optimized ophthalmic lens configured to be worn by a wearer, the method comprising:
- receiving initial lens shape data relating at least to a shape of an initial ophthalmic lens free of an initial nose pad;
- receiving morphology data relating at least to a morphology of the nose of the wearer;
- determining the shape of the nose pad configured to be part of the optimized ophthalmic lens configured to be worn by the wearer based at least on the initial lens shape data and morphology data;
- and
- determining an optimized ophthalmic lens shape of the optimized ophthalmic lens based on the initial lens shape data of the initial ophthalmic lens free of the initial nose pad, the optimized ophthalmic lens comprising the nose pad.
An optimized ophthalmic lens configured to be worn by a wearer, the optimized ophthalmic lens comprising:
- a protruding portion forming a nose pad, the protruding portion having a shape defined based on at least wearer morphologic data relating at least to the morphology of the nose of the wearer and initial lens shape data of an initial ophthalmic lens free of an initial nose pad.
A nose pad configured to be formed directly on an optimized ophthalmic lens configured to be worn by a wearer, wherein the nose pad is determined based at least on a wearer morphology data and initial lens shape data of an initial ophthalmic lens free of an initial nose pad.
