Abstract
One embodiment of an ocular lens includes a lens body configured to contact an eye where the lens body has an optic zone shaped to direct central light towards a central focal point of a central region of a retina of the eye. At least one optic feature of the lens body has a characteristic that directs peripheral light off axis into the eye away from the central region of the retina. Another embodiment of an ocular lens has at least one isolated feature of the lens body that has a characteristic of directing peripheral light off axis into the eye away from the central region of the retina. Methods of making contact lenses include forming the features during the manufacturing process.

An ocular lens, comprising:
- a lens body, the lens body including an optic zone shaped to direct central light towards a central focal point of a central region of a retina of an eye when disposed relative to the eye, and
- a semi-spherical or hexagonal optic feature protruding from the lens body defined outside the optic zone on the lens body that directs peripheral light into the eye away from the central region of the retina when the lens body is disposed relative to the eye, wherein the semi-spherical or hexagonal optic feature further causes the peripheral light directed away from the central region of the retina to have a focal point in front of the retina.
An ocular lens, comprising:
- a lens body, the lens body including an optic zone shaped to direct central light towards a central focal point of a central region of a retina of an eye when disposed relative to the eye, and
- at least one isolated semi-spherical or hexagonal feature protruding from the lens body defined outside the optic zone on the lens body that directs peripheral light into the eye away from the central region of the retina when the lens body is disposed relative to the eye, wherein the isolated semi-spherical or hexagonal feature further causes the peripheral light directed away from the central region of the retina to have a focal point not on the retina.
