Focus at very center until told to look away. (Actually 15 seconds or so will do it, just the illusion wont last as long.) Have the page full screen, and within 2 ft. or so.
Now move your eyes to something else, the wall, a picture, your keyboard.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
