Benjamin Franklin (January 17, 1706 to April 17, 1790) was a Founding Father and a polymath, inventor, scientist, printer, politician, freemason and diplomat. Franklin helped to draft the Declaration of Independence and the U.S. Constitution. As an inventor, Benjamin Franklin has created numerous contraptions but the focus is going to be his creation of the Bifocals. As Benjamin Franklin aged, his vision, which had never been great, deteriorated even further. Like many of the instances in his life when an ongoing challenge presented itself, Franklin devised an invention that would help him to see long distances and be able to continue his favorite hobby, reading.
He described his invention as "double-spectacles." The new version of Ben Franklin eyeglasses would come to be known as bifocals. The process of their invention was quite simple. In 1784, Franklin wrote to his optician and made a request: take both his long distance glasses and his reading glasses, slice their lenses in half and then suture the lenses together with the reading lenses on the bottom and the long distance glasses on the top. Franklin would be able to avoid the hassle of switching glasses while he moved between reading and walking about. There is further evidence from other …show more content…

Two decades after Franklin's death, Thomas Jefferson requested a pair of bifocals to be crafted for his use and described them as an invention of Dr. Franklin. After wearing them for a time, Jefferson reported to his hyperopic friend that he had "adopted Dr. Franklin's plan of half glasses of different focal distances, with great advantage.” 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

Born in 1706 as the eighth of 17 children to a Massachusetts soap and candlestick maker, the chances Benjamin Franklin would go on to become a gentleman, scholar, scientist, statesman, musician, author, publisher and all-around general genius were astronomically low, yet he did just that.

The ideals of the enlightenment are still thought of today, as they are a part of the United States’ Declaration of Independence and Constitution.

Franklin was known for creating many things that we still use today, and we will continue uses for many years to come. Inventions that we still use today would be the lightning rod, street lighting, odometer, Bifocal glasses, and the discovery of Daylight Saving Time. Franklin invented the lightning rod to protect the building from lightning; Franklin believed this was the most important inventions. With street lighting, he only improved it by using the scientific method to help improve the quality of light. As he describe it in his Autobiography, "I, therefore, suggested composing them of four flat panes, with a long funnel above to draw up the smoke, and crevices admitting air below, to facilitate the ascent of the smoke; by this means they were kept clean, and did not grow dark in a few hours, as the London lamps do, but continu'd bright till morning."

Franklin contributed some of his success in this area to his wife, whom he says is “as much dispos’d to industry and frugality as [himself]” (Franklin 37). Together, their table was “plain and simple”, their furniture “of the cheapest”, and Franklin’s breakfast was milk without tea, eaten out of a “twopenny earthen porringer” with a pewter spoon (Franklin 37). Franklin did not see value in upgrading his pewter spoon to silver or his cheap porringer to a china bowl. Franklin valued practicality and would rather avoid the enormous sum of “three-and-twenty shillings” for such things when the pewter spoon does the same job for a fraction of the price (Franklin 37). Franklin is frugal with his diet, as well.

Franklin vs. Jefferson An epic clash between two Founding Fathers! Both were prolific writers, Jefferson of the Declaration of Independence and his own version of the Bible, Franklin of Poor Richard 's Almanack and countless newspapers and pamphlets. Franklin invented the lightning rod, bifocals, and a carriage odometer, but Jefferson was no scientific slouch himself and filled Monticello, which he also designed, with a number of little inventions of his own, including a gadget that made copies of letters as he wrote them. Jefferson also carried out a number of early archeological studies.

Much of modern America is quite similar to Franklin in his actions throughout his lifetime. In his early years, Franklin’s father, Josiah, had a set plan for what he was supposed to do with his life, as a minister. Soon into his education, he found an interest in reading and writing, so he began pursuing a career in printing.
