During the early days of civilization, cultures all over the world used various visual aids, such as water bowls and vision stones to magnify images. Although the concept of glasses dates back to the early days of Roman civilization, it wasn’t until 1284, that the first wearable pair was invented by Salvino D’Armate. At that time, glasses were worn on the bridge of the nose, and prescribed for people who were farsighted.
Eye Glasses in Italy
During the 14th century, Italy gained much prominence in the eyeglass industry. They became world renowned for the quality and artistic quality of eye glasses they produced. Five-year eyeglasses were even invented because of the belief that poor vision began at the age of 30 and prescriptions only needed to be updated every five years.
By the time the 17th century rolled around, convex and concave lenses were invented. Using these lenses, glasses were created to treat people who required single lenses to see up close or far away. Benjamin Franklin, who suffered from both myopia and presbyopia, invented bifocals in 1784 so he wouldn’t have to switch back and forth between glasses. And in 1825, cylindrical lenses were created for people who suffered from astigmatism.
Today, eye glasses are used all over the world. They come in many different prescription strengths, colors, styles and price ranges.
