History of glasses

To this day, the origins of the first reading glasses are unknown. There is, however, proof of Roman literary figure Seneca using water-filled glass globule to read better. The concept then moved to Asia, where monks made use of convex glasses to magnify text.

 

Mainstream reading glasses came around the 13th century when glass blowers in Venice came up with lenses that were placed inside frames made of wood. They resembled magnifying glasses and were used to read small text.

 

Widespread belief exists that commercial eyeglasses were first made in Italy by combining two magnifying glasses. These were wrapped using metal or leather and placed over the nose to assist with reading. Subsequently, glasses found their way into art, where paintings depicting monks wearing glasses were popularized in 1352.

 

These glasses were predominantly used to assist with hyperopia, while the ones for myopia came about post-1400s.

Types of lenses

Frames

The first frames were introduced in the 1600s and strung together using ribbons. They were used to pull over the ears to keep them in place. In 1730, an optician introduced rigid temples that made glasses stay around the wearer’s temples.
