The earliest form of spectacle equipment can be traced back to 4000 years ago, and the culture that needs to adapt to the snowy climate created spectacles. This kind of glasses is made of bones and animal skins, with a small gap for people to see, but no lenses.

Early glass was called riveted glass. They are two magnifying glasses hinged on the bridge of the nose. The design of the glasses took a long time to perfect. Early glasses had no sides, just temples and arms. Before the 17th century, modern glasses mainly had a pair of frames with corrective lenses, a bridge of the nose connected to the frame, legs that could slide behind the ears, hinges that connected the chin to the frame, and some glasses had foot covers to ensure the back of the ears.

In American culture, the cinema in the 20th century promoted the promotion of glasses. The audience will see charming actors wearing glasses playing different roles.

Nowadays, glasses have become very popular as fashion accessories. In fact, some people wear glasses without prescription lenses because they want to express some of their characteristics.
Glasses are the lifeblood of man. People who can't drive, cook, or read because they can't see clearly, rely on glasses to make a living.
In human society, we have invented many other tools to help overcome various physical defects, but only glasses have become a fashion symbol by leaps and bounds. It would be great if any auxiliary device invented by any object we use can surpass its original purpose like glasses!
