TELESCOPIC CONTACT LENS
First Claim
1. A contact lens, comprising:
- a lens assembly structured to include a central aperture formed of a material capable of transmitting light through the central aperture to enter an eye behind the lens assembly as a first optical imaging device for forming images in the eye, an annular aperture separated from and enclosing the central aperture to receive light outside the central aperture, and an annular optical element coupled to the annular aperture to receive light from the annular aperture and to guide the received light along a folded optical path to enter the eye as a second optical imaging device for forming images in the eye that are optically different from images formed through the central aperture; and
a soft lens skirt formed outside the lens assembly to form contact with the eye.

Abstract
Techniques, systems and apparatus are described for implementing a telescopic contact lens. In one aspect, a telescopic contact lens includes an inner lens including optical apertures and aspheric reflectors, an outer lens of a biocompatible material, and a switching device that rapidly switches between normal and telescopic vision. The optical apertures of the inner lens includes a center aperture that allows light to pass through for normal vision and an annular aperture located on the periphery of the inner lens that allows light to enter for telescopic vision, The aspheric reflectors are configured between the annular aperture and the center aperture to reflect the light and magnify a visual image for telescopic vision.

14. A method for using a contact lens to form images in an eye, comprising:
-
using a central aperture of the contact lens as a first optical imaging device to form images in the eye in a first vision; using an annular aperture of the contact lens, that is separated from and encloses the central aperture, to receive light outside the central aperture, to guide the received light along a folded optical path to enter the eye as a second optical imaging device to form images in the eye in a second vision that is optically different from the first vision; and switching on and off the central aperture and the annular aperture, one aperture at a time, to form images in the first and second visions in the eye. - View Dependent Claims (15, 16)

17. A contact lens, comprising:
-
a lens assembly structured to include a central aperture formed of a material capable of transmitting light through the central aperture to enter an eye behind the lens assembly as a first optical imaging device for forming images in the eye; an annular aperture formed in the lens assembly, that is separated from and encloses the central aperture, to receive light outside the central aperture, and to guide the received light along a folded optical path to enter the eye as a second optical imaging device for forming images in the eye that are optically different from images formed through the central aperture; a central aperture shutter that shuts or opens the central aperture; an annular aperture shutter that shuts or opens the annular aperture; and an aperture control that operates one of the central aperture and the annular aperture to receive light for forming images in the eye while shutting down the other one of the central aperture and the annular aperture not to receive light. - View Dependent Claims (18, 19, 20, 21, 22)

32. A contact lens, comprising:
-
an inner lens including two or more optical apertures and optical reflectors, wherein the two or more optical apertures include a central optical aperture located in the center of the inner lens that receives light and directs received light onto a central region of a retina of an eye for normal vision and an annular optical aperture located on a periphery of the inner lens that receives light and directs received light along a folded optical path formed by the optical reflectors to magnify an image in the received light onto a peripheral region of the retina for a telescopic vision, and wherein the optical reflectors are arranged in a region between the annular optical aperture and the central optical aperture to reflect the received light from one reflector to another along the folded optical path that is separated from an optical path of the received light from the central optical aperture; and a switching device that is located on the exterior of the inner lens between the two or more optical apertures that switches between normal and telescopic vision. - View Dependent Claims (33, 34, 35, 36, 37, 38)

39. A contact lens, comprising:
-
a lens assembly structured to include a single annular optical aperture located on a periphery of the lens assembly that receives light and guides received light along a folded optical path formed by optical reflectors to magnify an image in the received light onto a region of retina of an eye for a telescopic vision, and wherein the optical reflectors are arranged in a region that is hollow between the annular optical aperture and the center of the lens assembly to reflect the received light from one optical reflector to another along the folded optical path; and a soft lens skirt formed outside the lens assembly to form contact with the eye, wherein the lens assembly is made of the same material as the soft lens skirt.
