  1. I wonder whether the pilot who claims that you cannot change your focus realizes that he can both see out the window of his plane as well as the instrument panel inside his plane, clearly. (The human eye is soft. Muscles around the eye change the shape of the eye, which alters the distance from the lens to the back of the eye where the light is detected. This change in distance changes the focal length.)
