I'm beginning to think you're describing what some might recognize as a "type two focus" or "seeing through your sights." Except that you are attributing an independant focus which I, and others, believe to be impossible. Are you sure you are using the word "focus" appropriately? "Distinguish" I can see, no pun intended, but not focus.
