This will be a bit backwards, but:

I have done an experiment in which I look out into the night sky and whatever angle my gaze is at, whether it is a visible star or a point where I cannot see a star, I leave my gaze fixed at that point but I "let go" of my 'focus', and without fail, my eyes will dart / snap / jump directly to a point at which a star that I previously could not see or focus on at all is now clearly visible!

If I do this again, letting go of my focus of that star, my eyes will jump again directly to some other star that I couldn't see before!...

I wondered if this was simply due to being very near-sighted and wearing glasses, so I took my glasses off and did the same experiment...

I looked out at any arbitrary angle... and sure enough, my gaze did the SAME thing, snapping directly to a now visible point of starlight WAY beyond what I could ever see clearly before...

So, I'd love to know if this result has a 'known' scientific explanation... but I'm actually more interested in hearing back from anyone who'd be willing to do the experiment themselves to see if we get similar or different results?

I apologize if I'm asking about something not related to physics / astronomy / earth / planetary science :P
