Peripheral retinal OCT can be used to generate peripheral retinal OCT images allowing for the peripheral retina to be viewed. A peripheral retinal vision system can determine that a set of fiducial markers is in a field-of-view of at least one camera and record positional data comprising a contact lens position and angle with respect to an OCT imaging system having OCT scanning mirrors in a first position. The system can determine whether a retinal layer is in an OCT scan captured while the set of fiducial markers is in the field-of-view of the at least one camera and the OCT scanning minors are in the first position; and for an OCT scan having he retinal layer and being captured while the set of fiducial markers is in the field-of-view of the at least one camera and the OCT scanning minors are in the first position, store that OCT scan.

An optical device can include: an incident light polarizer positioned to receive incident light and configured to polarize incident light such that polarized incident light is directed to a cornea of a subject; at least one corneal light polarizer, wherein the at least one corneal light polarizer is positioned to receive reflected light from the cornea of the subject and polarize the reflected light to a second polarization; at least one rotating mechanism; and at least one receiver. The receiver can be at least one viewing port optically coupled with the at least one corneal light polarizer or an imaging device (e.g., optical detector). The at least one rotating mechanism is: coupled with the incident light polarizer; coupled with the at least one corneal light polarizer; or coupled with the incident light polarizer and the at least one corneal light polarizer.

A contact lens according to an embodiment of the present disclosure includes: a lens section that is worn on an eyeball; an acquisition section that is provided in the lens section and acquires biological information; and an output section that outputs the biological information acquired by the acquisition section to an external apparatus to be worn on a human body. The output section has one or a plurality of coil antennas extending along a front surface of the lens section, and a capacitor that is coupled to the one or the plurality of coil antennas in series or in parallel.

A light adjustable lens illumination system comprises an illumination source, for generating a light beam; a light delivery system, for projecting the light beam onto a Light Adjustable Lens (LAL), implanted into an eye, wherein a fraction of the light beam propagates past the LAL to a retina of the eye; and a protective beam-shaper, for shaping the light beam to have an intensity pattern with a relative central intensity reduction that varies along an axis; wherein the relative central intensity reduction at the retina is greater than the relative central intensity reduction at a LAL plane.

A device for illuminating a posterior segment of an eye may include multiple channels. Each of the channels may include multiple illumination paths such as a first region illumination path, and a second region illumination path. The first region illumination path and the second region illumination path may be illuminated at different times such that a first region and a second region may be imaged without interference from a non-illuminated illumination path.
