6. The optical device of claim 1 , wherein the fan-shaped active area is configured to provide an area- or sector-specific supplemental lens/optic that operates in conjunction with the optical element or system.
7. The optical device of claim 1 , wherein the fan-shaped active area includes one or more refractive optics or optical elements.
8. The optical device of claim 1 , wherein the fan-shaped active area includes one or more diffractive optics or optical elements.
9. The optical device of claim 1 , wherein the fan-shaped optic is provided in the form of and/or includes at least a portion of an intraocular lens (IOL).
10. The optical device of claim 1 , wherein the fan-shaped active area includes or is provided with edge or side portions configured and/or treated to effect blocking or diffusion of light.
11. The optical device of claim 10 , wherein the edge or side portions include a light absorbing surface layer.
12. The optical device of claim 10 , wherein the edge or side portions include a surface treatment applied or provided such that gloss expressed at the edge or side portions is less than a gloss unit (GU) value or values specified in respect to the edge or side portions.
13. The optical device of claim 10 , wherein the edge or side portions include a surface finish applied or provided such that surface roughness at the edge or side portions has peak-valley height values of 7-15 microns.
14. The optical device of claim 10 , wherein the edge or side portions include nano-structures that have nano-tips or cones.
15. The optical device of claim 10 , wherein the edge or side portions include nano-structures that are cone-shaped or approximately cone-shaped, the nano-structures being 100-300 nm in base diameter and 1000-16000 nm in height.
16. The optical device of claim 10 , wherein the edge or side portions include nano-structures, the nano-structures including: nano-tips, nano-arrays, aperiodic or other arrays of nano-structures, antireflection structures, biomimetic structures, or a combination or combinations thereof.
17. The optical device of claim 1 , wherein the optical device further comprises:
one or more clip, claw, anchor, haptic or support structure.
18. An optical device, comprising:
a partial or incomplete optic configured operatively as an add-on for an optical element or system, the partial or incomplete optic having an active area configured in relation to the optical element or system such that the partial or incomplete optic controls or changes foci of light incident upon or provided to the active area, but does not control or change foci of light bypassing optically relevant portions of the partial or incomplete optic;
an opening that is adjacent to and/or not overlapping the active area;
a circumferential ring that defines a portion of the opening; and
a haptic or support secured to and configured to provide structural support at and about an entire periphery of the circumferential ring to prevent bending of the circumferential ring adjacent to the opening when arms of the haptic or support are compressed.
19. The optical device of claim 18 , wherein the partial or incomplete optic and the circumferential ring are made of a first material, and the haptic or support includes one or more periphery support/interface structures made of a second material that is harder than the first material.
20. An optical device, comprising:
a partial or incomplete optic configured operatively as an add-on for an optical element or system, the partial or incomplete optic having an active area configured in relation to the optical element or system such that the partial or incomplete optic controls or changes foci of light incident upon or provided to the active area, but does not control or change foci of light bypassing optically relevant portions of the partial or incomplete optic;
an opening that is adjacent to and/or not overlapping the active area;
a circumferential ring that defines a portion of the opening; and
a haptic or support secured to and configured to provide structural support at periphery portions of the circumferential ring to prevent bending of the circumferential ring when arms of the haptic or support are compressed.
21. The optical device of claim 20 , wherein the partial or incomplete optic and the circumferential ring are made of a first material, and the haptic or support includes periphery support/interface structures made of a second material that is harder than the first material.
22. The optical device of claim 20 , wherein the haptic or support includes periphery support/interface structures that are symmetrically configured in relation to one or more boundaries of the partial or incomplete optic.
23. The optical device of claim 20 , wherein the haptic or support includes periphery support/interface structures that are symmetrically configured in relation to the opening.
24. The optical device of claim 20 , wherein the haptic or support includes periphery support/interface structures that are not directly connected to other periphery portions of the circumferential ring and configured such that the optical device is foldable at said other periphery portions.
25. The optical device of claim 20 , wherein the haptic or support includes periphery support/interface structures that are configured at opposite sides of the optical device in relation to portions of the optical device at which the optical device is foldable.
26. The optical device of claim 20 , wherein the periphery portions are at opposing sides of the circumferential ring and approximately equidistant from an axis intersecting portions of the optical device at which the optical device is foldable.
