It seems more than likely that most alien species would have eyes (or at least some sort of visual receptors), given their immense value. Yes, I know that other species could live on planets in total darkness, but I highly doubt that given that handicap, they would advance to the point of even a Kardashev Type 1 civilization. Maybe giant bats at best. Not discounting nature's ingenuity, only saying the most likely reality given all we know about life.
