     What is the most important invention of all time? Is it the written word that helps us to record

  information? Is it the telephone that lets us talk to people from all over the world? Is it the car that lets us

  travel at great speeds to meet others? Umberto Eco,  an Italian writer, thinks it is something quite

 different. He says the most important invention might be bright in front of your eyes.  He is talking about

 a simple pair of glasses.

     Modern eye glasses were invented around 1000 years ago. They were more than just a convenient way

  to lead. Before glasses were invented, writers, scientists or teachers who could not see properly had to

 memorize everything.  After about ten years of poor eyesight, they could not remember well enough and

 could not work.  Glasses meant that people could work in their old age.

    People who wanted to remember some information could write it down and read it. Eye glasses are one

  of the world's greatest inventions and were probably worn by the people who designed the first telephone

  and the first car.
