I really don't care either... put dots on your "URB", smiley faces, corporate logos, whatever. You won't be the first or the last to do so.
But if your eyes are closed, why do you need them?
See how Edgar is not looking anywhere near the fingerboard? That's because he knows where his hands are going, and his ears will tell him when he's there. Having met Edgar, and knowing that he has a very sly sense of humor, I still think that part of the reason he put them on there was as a goof.
The eyes have almost nothing to do with it, in my experience. If you're looking at the fingerboard, your neck, shoulders, and back will be killin' you in short order.
I can't remember that last time I used my eyes to check out how I sound. Eyes are for one thing only... to check out the "talent" in the room.
