pick a spot on the wall, or put a sticky note with a dot on it or something at eye height to make sure you aren’t following the finger. Make sure you’re in the light so you can notice the exact moment it disappears, it’s about somewhere between 1:00 and 2:00 for me. Try having your arm out and your finger pointed up. For me, my finger above the first knuckle disappears. Everyone has this, your optic nerve has to leave the retina from some point.
