Do u know that the Camels have three eyelids to protect themselves from blowing sand ? Yeah. its a true fact. The Camels have three eyelids.Their two of the eyelids have eye lashes that help to protect eyes from sand & the third one is a very thin lid which works to clean off their eyes. So in a sandstorm the camels can close that lid to protect their eyes from the sand, but still see where they are going.
