Question

“I can’t see clearly, because I don’t wear my glasses today.” We always hear people saying something like this. Glasses are very important to many people. Do you know how they were invented and developed?

Glasses took a long time to develop into what you can find in the glasses store today. The Chinese first used colored glasses as fashion. They thought that those glasses had magic, but they didn’t think that glasses could help eyes to see clearly.

In 1262, the inventor, Roger Bacon, discovered the amazing function(功能) of lenses(鏡片), and he thought that glasses could be used to help people to see. Twenty years later, in Florence, Italy, the inventor, Alessandro di Spina, made the first pair of glasses that could help people to see.

Although these glasses worked, scientists didn’t understand how glasses helped eyes to see. They thought that eyes sent out light onto whatever a person was looking at, and then the light came back to the eyes. Johannes Kepler finally found out how glasses worked.

Inventors continued to improve glasses. In 1784, Ben Franklin created glasses that had bifocal(雙焦的) lenses. Many years later, in 1827, George Airy made circle-shaped glasses to correct astigmatism, an eye problem that stops the eyes from seeing things clearly.
