Contact lens

1. A contact lens comprising:

a contact surface configured to contact an eye of a user;

an outside surface opposite the contact surface;

a first orientation indicia that is visually detectable; and

a second orientation indicia that is visually detectable, the second orientation indicia positioned on the contact lens relative to the first orientation indicia in a predetermined relationship indicative of an orientation of the contact lens;

wherein except for the second orientation indicia the contact lens comprises a geometric shape, and the second orientation indicia comprises one of an aperture within the geometric shape, a protrusion extending along the contact surface beyond the geometric shape, and a cutout, and

wherein the second orientation indicia is circumferentially offset from the first orientation indicia.

2. A contact lens as in claim 1 , wherein the first orientation indicia comprises one of an aperture, a protrusion extending along the contact surface, and a cutout.

3. A method of making a contact lens, the method comprising:

providing a first orientation indicia on the contact lens, the first orientation indicia being visually detectable;

defining a predetermined relationship indicative of an orientation of the contact lens; and

providing a second orientation indicia on the contact lens based on the predetermined relationship, the second orientation indicia being visually detectable and circumferentially offset from the first orientation indicia;

wherein except for the second orientation indicia the contact lens comprises a geometric shape, and the second orientation indicia comprises one of an aperture within the geometric shape, a protrusion extending along the contact surface beyond the geometric shape, and a cutout.

4. A method as in claim 3 , wherein the first orientation indicia comprises one of an aperture, a protrusion extending along the contact surface, and a cutout.

5. A method of placing a contact lens, the method comprising:

obtaining a contact lens having a contact surface, an outside surface opposite the contact surface, a first orientation indicia that is visually detectable, and a second orientation indicia that is visually detectable and circumferentially offset from the first orientation indicia, wherein except for the second orientation indicia the contact lens comprises a geometric shape, and the second orientation indicia comprises one of an aperture within the geometric shape, a protrusion extending along the contact surface beyond the geometric shape, and a cutout;

sensing the second orientation indicia;

sensing the presence or absence of the first orientation indicia at a position indicative of a proper orientation of the contact lens;

if the first orientation indicia is present, placing the contact lens on the eye; and

if the first orientation indicia is absent, reversing the orientation of the contact lens and then placing the contact lens on the eye.

6. A method as in claim 5 , wherein the first orientation indicia comprises one of an aperture, a protrusion extending along the contact surface, and a cutout.
