Eyelids - yes, eyeballs - no, when the eyeball starts drying or you look at the sun your nervous system signals the brain to automatically squint, tear, and blink to keep the eyeball moist and lubricated. You would burn your retina rendering yourself blind long before sunburning the outer eyeball tissues. That is why you shouldn't stare directly at the sun for long periods of time or during an eclipse.
