From Ancient Times to the Modern Era
The history of lenses and glasses can be traced back to ancient civilizations, where the use of lenses can be seen in various forms such as magnifying glasses and burning glasses.
The ancient Romans and Greeks used lenses made of smoky quartz, which were used as magnifying glasses to help with reading and writing.

The first eyeglasses were invented in Italy in the late 13th century, and were used to correct farsightedness. These early glasses had convex lenses that magnified objects, and were designed to be held in front of the eyes rather than worn on the face.

In the 16th century, the design of eyeglasses changed to include a bridge and a frame to hold the lenses in place, and by the 17th century, the invention of the printing press had led to an increased demand for eyeglasses among people who needed them for reading.

Today, lenses and glasses have become a common sight, with millions of people using them to correct their vision and improve their quality of life. With the development of new materials and technologies, the future of lenses and glasses looks bright, and it is likely that we will see even more advanced and innovative designs in the years to come.
