When you can stim by looking at things, that's about as undetectable as it gets short of mentally playing with sounds or images or whatever.
Many years ago my daughter asked me why I was staring intently out of the window and moving my head slightly.
I told her i was looking at 2 pigeons and was adjusting my focus to make them into 3 pigeons. I needed to move my head to keep the roof level straight. I do this a lot.
As you say: it's a "safe" stim.
I'm trying to train myself out of staring at people. I do it a lot. They get uncomfortable - I don't notice. It doesn't help that my targets tend to be women I find attractive, or men I find threatening. Or sometimes they are simply where my eyes happen to be while I "zone out".
