Hooray for glasses!

Today in 1785 Benjamin announced his invention of bifocals.  This got me thinking of how  although I don't wear bifocals, I'm jolly glad glasses were invented. They've made all the difference to so many people's lives, including mine.  Glasses have allowed me to do things I love most: read, write, do research, and best of all travel (even if I lack a sense of direction!) I'm glad there are things in the world that give people the ability to do what they need to do in life. So I say thanks to Ben Franklin and everyone else who had a part in making glasses so great!
