C) James Madison D) Thomas Jefferson

Answer:   B) Benjamin Franklin



Explanation:

Benjamin Franklin has long been credited with the invention of bifocal lenses and he was the first to wear bifocal lenses.

He was tired switching between lenses for far and near sightedness. And that resulted in inventing Bifocal Lenses.
