Light control devices and methods for regional variation of visual information and sampling
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 generate a moving aperture effect anterior to a retina 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. 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.

wherein anterior to the retina comprises one of extraocular, intracorneal or intraocular placement,
wherein, upon receipt of the control signals, the optomechanical elements are moved to produce one or more areas of altered transparency, the one or more areas defining one or more apertures that include transparent areas,
wherein the one or more apertures are generated at spatially separated or overlapping positions on the surface of, or within, the one or more layers, and
wherein the one or more apertures generate 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.
8. The light control device of claim 7 , further configured to deliver approximately collimated light from the ocular field of view through at least one of the one or more apertures.
9. A method, comprising:
generating, using a light control device, a moving aperture effect anterior to a retina of an eye at a rate between 50 hertz and 50 kilohertz, the generating comprising generating a movement of one or more layers disposed anterior to a retina of an eye, the one or more layers comprising one or more apertures; and
using the light control device, sampling and delivering to the retina environmental light from an ocular field of view.
10. The method of claim 9 , further comprising sampling and delivering, using the light control device, approximately collimated light from the ocular field of view through at least one of the one or more apertures.
