Like snakes, their eyeballs are covered with spectacles—transparent scales that protect the eyes. To keep them clean, many species use their tongues like windshield wipers.
You may notice that most geckos have large bulging eyes–many that are intricately patterned and flecked with metallic hues. To protect their eyes while basking in the sun, most geckos have vertical pupils that close to tiny slits and block damaging rays. Some species have pupils with overlapping edges that close completely. They see through tiny pinholes formed by the scalloped shape at the edges of the pupil.
