Madara used it with no eyes, and Itachi used it when he was completely blind. Susanoo is awakened with the eyes, but as is shown you can use it with just your body. Itachi, Sasuke and Madara have each used it in Normal Sharingan form, and Itachi and Madara did it with no eyesight or eyes at all. So no the whole one eye argument of yours is bs UltimaDude.
