I noticed intense fatigue wandering Tokyo with my friend who wore magnifying lenses and he could not understand why I was tired. I said it's all the visual stimulation, the signs, the lights, the billboards. I think he was at an advantage with the eyewear, in retrospect.
I found the opposite personally. Something about the neatness and tidiness let my mind relax and see everything similar to a calm flowing stream. Tokyo is one of the most peaceful cities I've been to, even in the busy areas, and by far the biggest and most populated.
This may just be one small point, but I recall reading that visual clutter signifies a good bargain while lots of white space gives the impression of luxary. Most consumers want a good deal.
Its same for TimeSquare still people pay big dollars. Both things can be right, it has negative effect however it is still engaging and effective. It gets the eyeballs
