In 1284, the first wearable glasses in history were invented!, Before this tool, there was vision aid called the reading stone, which was invented in 1000 AD. It was glass ball that was placed over the reading material to enlarge the letters. Salvino D'Armate is often credited with inventing the first wearable eyeglasses, They consisted of primitive lenses made of glass or crystal placed in wooden or metal frames (or sometimes, frames made of animal horns), and there were no handles to attach them to the face, as the user had to place the glasses on his eyes to achieve the best vision. These lenses were used to correct vision for people who suffer from visual problems such as farsightedness and presbyopia. They were relatively heavy due to the use of heavy materials such as wood, metal, and glass lenses; In these glasses, there were no specific grades for the lenses. They were made based on the estimates and experience of the craftsmen without unified grading system. The visual needs of the person were roughly measured and the lenses were made according to these estimates. In primitive times, glasses were mainly used for reading and correcting vision when needed, and were designed to meet the basic needs of individuals in their daily lives. After the first glasses, eyeglasses have undergone great development. Technology and science have developed, leading to improved eyeglass design and lens quality. Multifocal lenses and digital lenses have appeared, lightweight materials and elegant frames have been developed, making eyeglasses an important part of people's lives today.
