Who invented bifocals?
It could be said that American pioneer Benjamin Franklin did, along with many other things. Anyone looking at a list of Benjamin Franklin's inventions would see a man of many talents and interests. Indeed, it was the scientist in Franklin that brought out the inventor - his natural curiosity about things and the way they work made him try to find ways to make them work better. For example, Franklin had poor vision and needed glasses to read. He got tired of constantly taking them off and putting them back on, so he decided to figure out a way to make his glasses let him see both near and far. He had two pairs of spectacles cut in half and put half of each lens in a single frame. Today, we call these types of glasses bifocals. Although he did make many important discoveries and advancements, Ben did not "invent" electricity. He did, however, invent the lightning rod which protected buildings and ships from lightning damage.
Benjamin Franklin was the inventor of the rocking chair.
