Have you read anything concerning how cephalopod and human eyes differ; or are you "shooting from the hip"?
Inverted Human Eye a Poor Design?
You will probably simply reject this article out of prejudice however if you take the time to read it you will find an excellent discussion of the cephalopod eye. BTW, if humans had a cephalopod type eye we could not fly an airplane, we probably could not drive a car or do any activity that required the ability to see images in sharp detail.
Now I will again ask why the human eye is poorly designed as compared to a cephalopod’s and how does our blind spot affect our lives?
