In 1608, an eyeglass maker from Middelburg, Hans Lipperhey, filed a patent application with the States General of Holland for a new optical instrument: a convex lens (for farsighted people) and a concave lens (for nearsighted people), mounted at the ends of a tube just over a hand's length, which magnified distant objects up to three times. Legend has it that one day in 1608, the eyeglass maker's sons began playing with the lenses their father had made in his workshop. By chance, one of them placed a concave lens near his eye, holding a convex one in his hand and pointing his arm toward the top of the cathedral bell tower. To his great surprise, the boy then saw the weathercock on the spire grow larger and move closer. Having shown the phenomenon to his father, he fixed the appropriately spaced lenses to a small board, thus making observation easier, giving rise to the first rudimentary optical approach instrument. Unfortunately for Lipperhey, however, within a few days other Dutch eyeglass makers also claimed the invention.
