Abstract
A device to stimulate the retina comprises one or more light sources coupled to one or more optical elements. The one or more optical elements is configured to illuminate the retina with one or more images at a location away from a fovea of a wearer. In some embodiments, each of the one or more images comprises a depth of focus and a spatial resolution. The one or more images can be formed at a distance anterior to the retina, at a distance posterior to the retina or on the retina. In some embodiments, the depth of focus is less than the distance, and the spatial resolution greater than a spatial resolution of the retina at the location.
