So for fun, I thought I’d stare into a mirror and watch my eyes when I did active focus. Since I’m still about thee diopters myopic, I can get rather close to the mirror, making depth perception quite effective.
What I did was place myself at the right distance for focus, then move back a few centimeters, then active focused to clear up the view. What was wild was what I saw. My eyes receded into the eye sockets a bit!
I did it several times to make sure, but my eyes actually back up in the socket a little bit as the view clears while I’m doing active focus. I’d say the movement is something like a millimeter or two.
Has anyone else noticed this behavior when actively focusing into a mirror?
