What happens in your eyes when you unfocus them?
In: 3
Your eye has a flexible lens that focuses light onto the retina. It’s deformed by tiny muscles. So when you unfocus your eyes, you’re just consciously deforming the lens in your eye so that the light coming in isn’t focused on the part of the retina it should be for proper vision.

It depends on what mean by “unfocus”.
Your eyes contain soft, clear lenses that change shape under the control of tiny muscles, to bring things into focus at different distances. If you look outer the window at distant objects, those muscles relax and nearby objects seem blurry, especially in dim light.
The other kind of unfocusing is when you relax your convergence- the tendency of your eyes to individually point at the thing you’re looking at. Your view can be parallel (at infinity) or very “cross-eyed” if you look at your own nose. You may see double images when you do this and it seems “unfocused”.
