Micro fenestrated contact lens
A sclera or contact lens with an image of an eye that is fenestrated, or uniformly speckled with many sub-millimeter sized transparent regions or holes, is disclosed. The micro fenestrated contact lens can be worn on a strabismic, or misaligned, eye so that its image is aligned with the wearer's dominant eye. The fenestrations allow the wearer to see through the opaque or translucent image printed on the contact lens, thus allowing binocular vision even though his or her strabismic eye is covered.
1. A contact lens apparatus for cosmetically improving strabismus comprising:
a contact lens body;
a fenestrated printing on the contact lens body, the fenestrated printing continuously spanning at least 10 millimeters (mm) in diameter, the fenestrated printing depicting a pupil, an iris, and portions of conjunctiva and portions of a sclera, the fenestrated printing uniformly interspersed throughout an entirety of the fenestrated printing with an array of transparent fenestrations, each transparent fenestration having a maximum dimension of 300 microns (μm),
wherein the fenestrated printing is configured to camouflage a wearer's strabismic pupil and iris, and the transparent fenestrations are dimensioned and spaced to allow partial vision through the fenestrated printing.
2. The apparatus of claim 1 wherein a spacing of the array of transparent fenestrations bears a transparent-to-opaque ratio for the fenestrated printing of less than 1.5:1.
3. The apparatus of claim 1 wherein portions of the conjunctiva and sclera depicted by the fenestrated printing extend at least 2 mm from the depiction of the iris, thereby being configured to cover at least a portion of a deviated iris of a wearer.
4. The apparatus of claim 1 wherein whitish portions of the sclera depicted by the fenestrated printing extend to a diameter of at least 12 mm.
5. The apparatus of claim 1 wherein whitish portions of the sclera depicted by the fenestrated printing are not symmetric around the depiction of the iris.
6. The apparatus of claim 1 wherein shapes and/or sizes of the fenestrations vary randomly or regionally.
7. The apparatus of claim 1 wherein the maximum dimension of the fenestrations is between 100 μm and 200 μm.
8. The apparatus of claim 1 wherein the depiction of the pupil, iris, and portions of the conjunctiva and sclera are from a photograph.
9. The apparatus of claim 8 wherein the photograph is of an eye of an intended wearer.
10. The apparatus of claim 1 wherein the fenestrated printing is opaque or translucent except for the fenestrations.
11. The apparatus of claim 1 wherein the fenestrations are holes through the contact lens body.
12. The apparatus of claim 1 wherein the fenestrations are polygons or circles.
13. The apparatus of claim 1 wherein the contact lens body comprises polymacron or is a rigid, scleral lens.
