What are "glasses"?

Glasses are a type of eyewear that are worn for vision correction or protection from harmful light and radiation. They consist of a pair of lenses that are held in place by frames, which can be made of various materials such as plastic or metal. Glasses can be designed for various purposes, such as reading, driving, or working on a computer, and can come in different styles to match personal preferences and fashion trends. Some glasses also have special features such as anti-glare coatings or polarized lenses for additional protection and comfort.
