Why doesn’t our brain recognise bad vision and realign the cells of the eyeball to restore perfect vision?
In: Biology
It does. Except that your brain doesn’t have that much control over the structure of the eye, all it can really do is turn the eye in different directions and manipulate the shape of the lens within a certain range, and admit more or less light within a certain range. If better vision lies outside the range of how much light it can let in or how much it can reshape the lens, it’s not like the brain can break out a whiteboard and redesign the eye from scratch to produce what you think is perfect vision.
Same reason your brain can’t redesign the bones in your arm to reach around corners better. It’s limited by the structure that already exists.
