Eyeglasses
The first historical account of glasses came in the 8th century BCE from ancient Egyptian hieroglyphs describing a lens of magnification. From then to now, glasses have come a long way. We have them to keep the light out of our eyes, to read words close-up or to see things from far away. If you use glasses to correct a vision problem, you will probably go through many pairs of them in your lifetime. So what do you do with those leftover spectacles?
