Which of the following refers to a part of glasses that helps focus images?

The lens is the part of glasses that plays a crucial role in focusing images. It is made of transparent material that bends and refracts light, allowing your eyes to see clearly at various distances. The curvature of the lens is designed to correct vision issues, such as nearsightedness or farsightedness, by directing light rays onto the retina in a way that enhances clarity.

In contrast, the frame holds the lenses in place and provides structure and support for the glasses. The bridge connects the two lenses over the nose, and the temples are the arms of the glasses that extend over the ears. While these components are essential for the overall functionality and comfort of glasses, they do not have the optical properties needed to focus images. Therefore, the lens is specifically responsible for the refractive task of focusing light on the retina, making it the correct answer.
