Why does vision become blurry/out of focus when you zone out and stare at one point?
In: Biology
Your eyeballs have small muscles inside them that bend the lenses of your eyes (corneas). That’s how focusing works.
When you relax your eyes, you’re relaxing those muscles. Whatever tension they were maintaining to keep your vision focused on the thing goes away, so your focus goes away.
That is a part of it, the other is your eyes are no longer pointing at exactly the same point as the point of focus you are looking at.
Your brain sees 2 pictures misaligned and does it’s best, but you get a blurry picture as a result.
