The three methods Leeuwenhoek used to make his lenses:grinding, blowing, and drawing.First came eyeglasses. For centuries after Alhazen and Roger Bacon first described lenses, people ground crude glass lenses to aid sight. Magnification of two or three times was usually sufficient. In addition, the human eye doesn't need very much of the lens at any given time, so the lens does not need ...
