  Well, I guess your thumb disappeared.

  I can try another way the blind spot is about 15 cm at arms length to the right of the right eyes center of vision. So put your thumb there and it should disappear

  Because of this we have blind spots, one for each eye. They are not usually noticeable because 1) the blind spot of one eye can be seen by the other, and 2) the brain fills in the gap.

  So with this I will perform a magic trick, I will make your thumb disappear: Close your left eye and with your right look at a spot in the background, make a thumbs up gesture and place the tip of your thumb on that spot, move your thumb to the the right continuing to look at the spot in the background, when your thumb moves about 15 cm your thumb should disappear.

  You can use you left eye too, just switch the directions.

  I don't think you understand correctly. The cephalopod eye and the fish eye (which includes tetrapods) evolved independently.
