Evolution I guess. Instead of having closable eyelids, their eyes are protected by a transparent scale (called the 'brille') Under the surface, the eyeball can still move.
A snake's eye is covered by a transparent, waterproof scale.
Not their entire eyes - but ... There is a transparent, protective covering over the snakes eyes - called the 'brille' It is discarded with the old skin each time the snake sheds - as it develops a new one with the creation of the new skin

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.
A "snake eye" in craps is when you roll two 1's. Therefore there are 2 snake eyes in the game.
That would be called the cornea. It's the transparent layer covering your eyes.

A snake cannot wink it's eyes because it doesn't have eyelids, But the can in your imaginations.
