If you wear glasses I suggest trying both with and without your glasses on while moving your head. For me, there is almost no effect without my glasses on. But with glasses, it is quite strong... but I'm not even sure if what I'm seeing when I have my glasses on is actually the intended effect. I've become used to that effect with blue and red light moving in opposite directions relative to each other when I move my head.

Weirdly I'm the opposite; red looks closer to me with my glasses off, but both colors appear about the same with them on.

-3.5 here, the illusion is both effective with or without glasses

+1 makes red pop out very strongly for me. Without glasses only very slightly.
