Why can't my brain correct my vision (details)?

Asked by MakeItSo1701 (13536points) 2 hours ago

If this is how we really see, and our brain corrects it to how we see now, why can’t it fix blurry vision?

That image is blurry, upside down, black spots, weird eye veins and our brain has no problem correcting it.

I get vision is also how light hits our eyes, but you cannot tell me that image above has nothing to do with the way light hits our eyes?

So, why can I not see? My vision is really bad, everything blends together. I could not function without my glasses, literally.

My prescription is -6 right eye, and -7 left eye.

Not entirely sure I understand the question. Are you asking why is it you can’t see without your glasses or are your glasses not working?

Oh sorry. I can try to rephrase.

The image I posted is what our eyes see, but our brain corrects it so we don’t see the black spots, it is not upside down, etc.

That is quite a correction.

So I am asking, if our brain can correct that much weird information, why can it not fix blurry vision. Why does anyone need glasses?

Edit: Yes, I used myself as an example. Sorry. That probably confused things.

The brain will correct an image that is in focus, but it can’t correct a bad image.

It already is correcting a bad image, is it not?

I am seriously not understanding this. ChatGPT says it works because it is a consistent distortion that our brain corrects, but surely my blurred vision has been distorted long enough for it to be consistent?

I get what you mean Zenvelo it just is not clicking in my brain.

Can your brain translate Swahili without ever hearing it before ? ?

MakeItSo1701's avatar

But I haven’t been blind since birth! And if we always see distorted, how does our brain know what “normal” is?

To your analogy, the clear image we see would be the foreign language, since the real image is highly distorted

So you can speak and understand Swahili ? ?

MakeItSo1701's avatar

Nope, but my eyes can understand “normal” right side up vision without ever having seen normal vision since birth.
