I have been shooting with both eyes open for some time now. After some practice it becomes second nature. I can pick up the arrow flight much faster and watch impact, like watching the flight in slow motion. I don't know how you guys do it with off eye dominance. We have one fingers shooter at our club that shoots right hand while aiming with his left. Somehow he looks over the string. Well, I guess what ever works well, stay with it. Just can't figure out how it's done.
