How can you divide Glasses?

Glasses can be divided based on several criteria, including their purpose (e.g., prescription, reading, sunglasses), style (e.g., full-frame, rimless, cat-eye), material (e.g., plastic, metal, acetate), and lens type (e.g., single vision, bifocal, progressive). Additionally, they can be categorized by brand or designer, as well as by specific features like polarized lenses or blue light blocking technology.
