It is unclear when the glasses were first made. However, the origin of the lens used by the British philosopher Roger Bacon as the origin of the glasses and the description of Marco Polo's oriental servants in China as wearing the lens are raised as well. Others have explained that many people used glasses in the 13th century in Florence, Italy.
The purpose of the glasses was to protect tired eyes, read books, and correct darkened vision. As is the case in the modern world, many people have glasses to protect their eyes and to make them look better.
Glasses have become a necessity in everyday life for many people. It is because I go out wearing glasses when I am at home. On sunny days, sunglasses designed for ultraviolet protection and vision protection are often used.
Glasses gradually develop to meet the needs and needs of people. Because everyone's eyesight is different, I have the ability to adjust the lens accordingly. Glasses for viewing 3D movies also appeared. There are smart glasses that are currently being developed and in progress. Perhaps at the completion of smart glasses, most people may use the glasses regardless of their eyesight.
