No snakes have eyelids as such. They have a clear membrane over the eyeball called the 'Brille' - it is discarded each time the snake sheds, and a new one is formed with the new skin. See related link for a better description.
No they don't...
Snakes have a clear membrane covering the eyeball called the 'Brille'. This clear lens is discarded every time a snake sheds its skin, and is replaced with the new skin growing underneath.

Snakes have no eyelids, and so they appear to sleep with their eyes open. In that sense, no, snakes eyes do not "look different" when they're sleeping.In the place of moving lids, snakes' eyes are protected by transparent layer of scales called spectacles which help both protect the eyes and keep them moist - just as eyelids do for other animals.
Snakes' eyes are covered by their clear scales (the brille) rather than movable eyelids. Their eyes are always open, and for sleeping, the retina can be closed or the face buried among the folds of the body.
Scales benefit snakes by protecting their bodies when they slither.
They are homologous structures. Both are scales, but snakes use them to move and pangolins use them as defense
Yes. Snakes do have scales.
Of course, the snakes of the world all have scales because they are cold blooded, if they were warm blooded, they would be a mammal and they would probably have fur, so, yes, snakes do have scales.
