I don't know. Seems to me that one attribute generally favored by natural
selection is increased awareness of one's environment. Vision has proven to
be a very effective means of processing information about the environment
and vision is the most important sensory modality for humans. It would be
pretty surprising to me if it weren't important in most alien species (if
they exist) as well.
