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 method, comprising:
delivering to a retina of an eye, using a device comprising one or more layers and located anterior to the retina, environmental light from an ocular field of view, the delivering comprising delivering approximately collimated environmental light through one or more collimating apertures in the one or more layers, and the one or more collimating apertures generating a moving aperture effect at a rate of at least 50 hertz based on a speed of fixational movements of the eye.
2. The method of claim 1 , wherein the one or more collimating apertures are surrounded by at least one area varying from the one or more collimating apertures in at least one of defocus, index of refraction or optics.
3. A method, comprising:
delivering, to a retina of an eye, and using a device comprising one or more layers and located anterior to the retina, environmental light from an ocular field of view, and adjusting the one or more layers of the device, the one or more adjusted layers comprising one or more collimating apertures, the one or more collimating apertures being surrounded by at least one area varying from the one or more collimating apertures in at least one of defocus, index of refraction or optics, and the one or more collimating apertures generating a moving aperture effect at a rate of at least 50 hertz based on a speed of fixational movements of the eye.
