US statesman Benjamin Franklin has long been credited with the invention of bifocal spectacle lenses.

Bifocals are attributed to Ben Franklin and he probably came up with the idea by himself. He did not produce them himself but instead had some optician in London or France make them for him. Franklin and his close circle of friends, including West and Reynolds, all probably wore them.
