Abstract: A soft contact lens comprises a plurality of light sources coupled to a plurality of optical elements. The plurality of light sources and the plurality of optical elements are embedded in a soft contact lens material. Each of said plurality of optical elements generates an image focused in front of a peripheral retina of a wearer. In some embodiments, each of the images is focused at a distance in front of the peripheral retina at a location, and each of the images comprises a depth of focus and a spatial resolution. The depth of focus can be less than the distance, and the spatial resolution greater than a spatial resolution of the peripheral retina at the location.

Abstract: An apparatus to treat refractive error of the eye comprises one or more optics configured to project stimuli comprising out of focus images onto the peripheral retina outside the macula. While the stimuli can be configured in many ways, in some embodiments the stimuli are arranged to decrease interference with central vison such as macular vision. The stimuli can be out of focus images may comprise an amount of defocus within a range from about 3 Diopters (“D”) to about 6 D. In some embodiments, the brightness of the stimuli is greater than a brightness of background illumination by an appropriate amount such as at least 3 times the background brightness. In some embodiments, each of a plurality of stimuli comprises a spatial frequency distribution with an amplitude profile having spatial frequencies within a range from about range of 1×10−1 to 2.5×101 cycles per degree.
