                                       THE 3 MOST IMPORTANTS
                          DISCOVERIES IN THE WORLD

The eyeglasses are one of the most importants discoveries, as a lot of people cant see very well and they arent know why.But Salvino D'Armate  invented eyeglasses in around 1285, though various sources suggest an earlier origin.In the 14th century, Venetian craftsmen were making "disks for the eyes"'. Italians gave these glass disks that were finely ground the name lenses because they were similar in shape to lentil beans. The earliest lenses were convex, the bulged outward in the middle, and they were used to correct far-sightedness.


The light bulb was invented by Thomas Alva Edinson in 1879, 
  although he could be said to have created the first commercially practical incandescent light. He was neither the first nor the only person trying to invent an incandescent light bulb. In fact, some historians claim there were over 20 inventors of incandescent lamps prior to Edison’s version. However, Edison is often credited with the invention because his version was able to outstrip the earlier versions because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve and a high resistance that made power distribution from a centralized source economically viable.





 The wheel was invented by John Dunlop
 A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the main components of the wheel which is one of the six simples machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines.
