How level is "level" to the naked human eye? (lemmy.ml)

I was putting up some wall decorations earlier today and was painstakingly realigning everything until it looked level to my eyes. It might be just a hair off, but if I don't correct it, I'll see the misalignment almost instantly and get bothered for the rest of time until I fix it. Has anyone investigated, or is there literature on the minimum perceptible angle from level to the naked eye?

Since the imperfections of your room may make what looks level not perfectly level, I say don't use a spirit level. You want it to look right.
