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.
1 . A light control device comprising one or more layers disposed anterior to a retina of an eye, wherein:
the one or more layers comprise or are configured to be adjustable to comprise one or more collimating apertures;
anterior to the retina comprises extraocular, intracorneal, or intraocular placement;
the light control device is configured to deliver approximately collimated environmental light from the ocular field of view through the one or more collimating apertures;
the one or more collimating apertures are surrounded by areas having a different defocus, index of refraction, contrast, chromaticity, transparency, or optics than the defocus, index of refraction, contrast, chromaticity, transparency, or optics of the one or more collimating apertures; and
the one or more collimating apertures generate a moving aperture effect at a rate of at least 50 hertz based on a speed of fixational movements of the eye.
