    Its elliptical pupil is tell tale nocturnal, and being like that and can open up pretty much fully to the edges of its eye, most geckos have no eyelid so one reason its eye is o-o-o so when its fully closed it can still allow a tiny amount of light in but the pin head sized holes focus the tiny amounts of light to the same point so it gets a clear image in bright light, allowing it to sleep and see predators.

    Tokay geckos have 4 points and an equally amazing eye.
    And it is design, though the same gene is used in every creature with an eye, circumstance and habitat crate it what it is. not god lol…
