Glasses are made of glass with a frame that helps people to see things better or protect their eyes. In fact, the main material of glasses is glass, which dates back to 4 500 years ago. It is known that ancient world people are aware of optics, that they notice that a certain form of glass magnifies objects.

However, it took a lot of time for the magnifying glass to turn into glass. It is not known who is the first person to find the glasses. The history of humanity owes a big thanks, but it still keeps secrets in spite of all the investigations of who made this brilliant invention.
The eyeglass târihi is very old. Marko Polo wrote in 1270 that the elderly people in China used glasses to see nearby. In Europe, Bacon talked about the need to wear glasses for elderly people.
It is a great possibility that this person lived in Venice in 1250 or 1280, because the first primitive glasses were sapeless, sitting on the nose, iple connected or hand-held.
Popozo wrote: “Old age took so much from me that I can neither read nor write without glasses called glasses. Richard Corson, who wrote a book in 1967 in London called “The Spectacle Through History”, states that the eye was discovered by the Italians in 1287. This is a wonderful device, which has been recently discovered for poor old people who have lost sight of their ability to see.
The lenses of the first goggles were convex, ie convex, and only those with vision problems helped to do their job.
It would take more than a century to produce concave (concave) lenses that would appeal to those with vision problems. As you can see, the development of the eyeglasses in history is rather slow. The problem of seeing in the distance, that is, the lenses that will correct myopia can only be done in the 15th century because at that time the eyeglasses should be used for reading more closely, not being considered as far away and not being more expensive and difficult to manufacture. However, after 350 years, it could be held in the middle of the face without falling.
Edward Scarlett invented a fixed eyewear staple in London in 1730. As the stems could be adjusted to the head, the glasses made less weight on the nose, and the danger of falling was also prevented.
Priorities used by scholars. It became widespread after the seventeenth century. In 1784, Benjamin Franklin discovered two bifocal glasses, and from then on, various progresses in glasses and frames followed each other. The prisms were made by Kepler in 1611; and astigmat glasses were made in 1827. Despite all this slow development, eyewitness service to humanity was great, at least they increased their loyalty to life. After increasing the number of printed books and newspapers in the printing house, it became a necessity since the glasses were luxurious.
