Just a different species of rock. There are fish with no eyes, and lizards. Why couldn't an eyeless kind of rock evolve if they originated in a place where eyes would not be beneficial?
Yea could be possible. If I remember correctly from the book, rockys planet is completely dark. But maybe there are some smaller light sources on the planet.

The "rock planet" is Earth when life didn't evolve which somehow has a blue sky.
