Why doesn’t our brain recognise bad vision and realign the cells of the eyeball to restore perfect vision?
In: Biology
Well, there are tons of different reasons for bad vision. Things like cataracts are clouding of the lens of the eye. Astigmatism is the curvature of the cornea being off. Then there’s things like retinopathy, where it’s part of the retina in the back of the eye, starting to die.
So there’s tons of different problems, and the brain can not control directly how cells divide. If it could, then we would never get scars because it could tell skin cells how to repair properly, we’d never get cancer because it could tell the good cells to kill the bad cells.
Cellular division is usually based on the other cells that are in that area. So if you had an astigmatism and scratched your cornea, the new cells that come in just tell it to grow back the same as the damaged ones, so you’ll still have the astigmatism.
