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.
Optical fabrication and testing spans an enormous range of manufacturing procedures and optical test configurations.. The manufacture of a conventional spherical lens typically begins with the generation of the optic's rough shape by grinding a glass blank. This can be done, for example, with ring tools. Next, the lens surface is polished to its final form.
