Snakes sleep with their eyes open because they dont have any eyelids. Their eyes are covered by a clear scale called a spectacle. You can see this when your snake sheds its skin. Some scientists believe that snakes went through a period in their evolution when they were underground and lost their eyes compeletly. That may be why snake eyes have a very different structure than any other kind of animal. they dont have eyelids..but they still sleep..you can tell by looking at the eye..if its like a very thin line in the middle..they're asleep.. make sure u wake them up 1st by tapping the cage before picking it up..they get aggresive when u shock them
Because the have no closable eye-lids. They have a clear lens over the eye-ball - called the 'brille'

A snake does not have eyelids so it cant close its eyes .
Eye lids
Not all turtles sleep with their eyes closed. My yellow slider sleeps with its eyes closed but my Map turtle sleeps with them open so it depends on the turtle.

A "snake eye" in craps is when you roll two 1's. Therefore there are 2 snake eyes in the game.

Borrowed from Rasputin: http://library.thinkquest.org/11922/reptiles/snakes.htm A snake's eyes are rounded and with lenses adjustable for distance vision. With the exception of the blind snakes, the eyes of a snake are permanently covered and protected by a transparent lower eyelid (called a spectable or brille). The fusion of the eyelids does not allow a snake to blink or close their eyes. Since the snake lacks external ear openings and eardrums, they hear by using their head to pick up vibrations and sounds from the ground. Experiments have shown that snakes can hear airborne sounds as well, although not well.
