Explanation:
Detailed explanation-1: -Bifocals are commonly prescribed to people with presbyopia, a condition that Franklin suffered. Franklin wrote, in August 1784 to his friend George Whatley, that he was “happy in the invention of double spectacles, which serving for distant objects as well as near ones, make my eyes as useful to me as ever they were."
Detailed explanation-2: -When Franklin’s eyesight deteriorated with age, he became both nearsighted and farsighted. He didn’t like the trouble of switching between two different pairs of eyeglasses, so he came up with an invention that he called double spectacles.
