To an extent, yes, it depends on the species of crab Dungeoness crabs, and blue crabs (The most common in seafood resturaunts) have bristle like things around the edge of the sockets that brushes the debris from the eyes. Land crabs like Patriot crabs and ghost crabs have foldable "Mouth Hands" that are basically like little windshield wipers. The exeption to the land crabs is the Halloween Crab which have eye mor similar to Dungeoness crabs. Hermit crabs and subsequently crabs with similar front structure like Japanese spider crabs can fold their eyes down and also have "Mouth Hands" although all crabs have a thin, nearly invisible, coat of skin covering their eyes if you wish to see it I suggest looking for molted crab skins on the beach. Hope this helped!

Yes!They can blink.
Most vertebrate animals can blink and have to blink in order to keep their eyes moisturized and clean. Some animals that can not blink are snakes and some breeds of lizards. Invertebrates generally cannot blink, often because they either have a different type of eye or because they don't have eyes.
