    Abstract: An apparatus to treat refractive error of an eye comprises an electroactive component configured to switch between a light scattering or optical power providing configuration to treat refractive error of the eye and a substantially transparent configuration to allow normal viewing. The electroactive component can be located on the lens away from a central axis of the lens to provide light to a peripheral region of the retina to decrease the progression of myopia. The electroactive component can be located on the lens away from the central axis of the lens in order for the wearer to view objects through an optical zone while the electroactive component scatters light. The electroactive component can be configured to switch to the substantially transparent configuration to allow light to pass through the electroactive component and to allow the lens to refract light to correct vision and allow normal viewing through the lens.

    Abstract: A stimulus is configured to treat astigmatism with changes in retinal thickness, independently of, or in combination with, treatment for myopia. In some embodiments, a stimulus pattern is arranged with respect to an astigmatic axis of the eye to decrease ocular growth in relation to the astigmatic axis. In some embodiments, the apparatus is configured to direct light to regions of retina outside the macula in relation to the astigmatic axis of the eye. In some embodiments, the intensity is modulated to provide the effect. A lens, such as a contact lens or spectacle lens may be configured with a plurality of light sources, such as projection units having a light source and focusing optics that work together to project anteriorly or posteriorly defocused images onto the retina at locations eccentric to the fovea.
