1. An apparatus to treat refractive error of an eye, the apparatus comprising:
an optic comprising an optical zone;
a display coupled to the optic, the display having a periphery extending beyond the optical zone; and
a peripheral defocus optical structure coupled to the display to form images of a plurality of stimuli anterior or posterior to a peripheral portion of a retina of the eye;
an adhesive to couple the peripheral defocus optical structure to the display;
a plurality of substantially transparent electrodes; and
a liquid crystal material between the plurality of substantially transparent electrodes;
wherein the liquid crystal material and the peripheral defocus optical structure are positioned between the plurality of substantially transparent electrodes to activate and deactivate an optical power of the peripheral defocus optical structure.
