Is it normal to unfocus your eyes?
Yep.Totally normal
Yes, it’s normal to unfocus your eyes on purpose. Lots of people can relax their focus or let their eyes drift briefly, though not everyone can do it easily.
You’re usually just relaxing the muscles that help your eyes focus, or letting your eyes stop aiming at one particular point. It can make things look blurry or double for a moment, and some people can do it more easily than others.
If your vision keeps going blurry without you choosing to, you have trouble refocusing, or you notice a sudden change, get it checked. Otherwise, a quick intentional unfocus is generally nothing to worry about.
