Such damage is creeping and the brain can just hallucinate the blank patches in the vision away, until only like 10% of the retina is left and it just doesn't work anymore. These days, dumbass laserheads are the most likely to suffer from that problem.
It's amazing how much of our conscious experience is hallucination, and yet a lot of people are disparaging LLMs for doing just the same...
probably because when humans pay full attention and think clearly they can not hallucinate for 99% of things they can sense (disregarfing optical illusion), but there is no 'pay attention and dont hallucinate' switch for LLMs.
People are bullshitting just the same about topics they know nothing about. They often also won't shut about when others tell them and even when they themselves know that they know nothing. To some extent this is necessary for humans to function at all, and the scientific process starts out from uneducated guesses and rigorously refines them and casts away what doesn't hold up to empiric data.
Optical illusions are evidence of the pile of hacks that our senses and our consciousness use to make sense of the world. I think it is really difficult to fully disengage from the biases this induces, and we are sadly best at perceiving such flaws in others. This might be one of the reasons why humans have to socialize with other humans to maintain mental health.
