Light control devices and methods for regional variation of visual information and sampling
First Claim
1. A light control device, comprising:
- one or more transparent layers disposed anterior to a retina of an eye;
one or more optically active elements disposed on a surface of, or within, the one or more transparent layers; and
a controller coupled to a power source, the controller being coupled electrically to the one or more optically active elements via an electrically conductive layer and being configured to generate and route control signals to the one or more optically active elements in accordance with a temporal sequence;
wherein anterior to the retina comprises one of extraocular, intracorneal or intraocular placement;
wherein, upon receipt of the control signals, the one or more optically active elements produce one or more areas within the one or more transparent layers having a reduced transparency, the one or more areas having the reduced transparency surrounding and defining one or more apertures that include corresponding transparent areas; and
wherein the one or more apertures appear optically at spatially separated or overlapping positions within the one or more transparent layers in accordance with the temporal sequence, at least one of the spatially separated or overlapping positions being coaxial with a center of a pupil of the eye, and the one or more apertures generating a moving aperture effect that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz.

Abstract
Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods may optically move, at a sampling rate between 50 hertz and 50 kilohertz, one or more apertures anterior to a retina between one or more positions anterior to the retina that are non-coaxial with a center of a pupil and a position anterior to the retina that is coaxial with the center of the pupil. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.
