Show Answer

Answer: Option B. Bifocal spectacles

Benjamin Franklin created bifocal spectacles in 1760. With his struggles with poor vision, Franklin faced the inconvenience of repeatedly switching between glasses for reading and distance vision. To tackle this issue, he ingeniously sliced two pairs of spectacles in half and merged parts of each lens into a single frame. This innovation allowed him to see both near and far without needing to swap glasses constantly. Today, we refer to these as bifocals.
