What are the two main parts of eyewear?

The two main parts of eyewear are the frames and the lenses. Understanding this distinction is fundamental when discussing eyewear design and function. The frames serve as the structural support that holds the lenses in place and accommodates features such as temples, which help to secure the eyewear on the face. The lenses are the optical components that correct vision or provide protection from the sun or other elements.

The choice of frames impacts not only the style and comfort of the eyewear but also the fit of the lenses, while the lenses are essential for visual clarity and protection. Together, these two components make up the essential elements of functional eyewear, which is a critical aspect to grasp for anyone studying optical sciences or related fields.
