What alternative name is given to the straight-back temple?

The straight-back temple is commonly referred to as the "library temple." This name originates from its association with eyewear styles that are often worn in more formal or subdued environments, such as libraries, where the straight design provides a classic and unobtrusive appearance.

Library temples are characterized by their straight design that arcs very little as they extend back toward the wearer's ears. This contrasts with other temple styles that may have more curvature or features suited for different occasions or functional uses. Understanding this terminology is essential for recognizing the variety of temple designs available in eyewear and their appropriate applications in fashion and function.

The other terms listed, such as "skull temple" and "convertible temple," refer to different styles that have distinct features and uses. A skull temple typically has a slight curve that follows the shape of the skull, providing a secure fit, while a convertible temple usually implies a design that can be adjusted or transformed for different styles. Knowing these distinctions further enhances your understanding of eyewear terminology and design.
