Do spiders have eyelids?


Chris - They don't. Spiders have several pairs of simple eyes that filter light through a lens material onto photo receptors, light-sensitive structures, underneath. They don't have a call for having any kind of eyelid type structure. Their eyes are open all the time, so they'll keep an eye on you because they've got plenty of them!


It isn't true that spiders have compound eyes like insects. They instead have several pairs of simple eyes.
