What type of temple is made of a flexible coil of metal and follows the contour of the skull?

The type of temple that is made of a flexible coil of metal and follows the contour of the skull is known as a comfort cable temple. These temples are designed to provide a snug fit against the head, which can enhance comfort and stability, especially during physical activities. The flexible metal coil allows for a customized fit, adapting to various head shapes and sizes. This design reduces pressure points and the likelihood of slipping, making them particularly advantageous for individuals who are more active or wear their eyewear for extended periods.

In contrast, library temples are typically straight and extend along the side of the head without providing the same level of contour. Convertible temples allow for different adjustments or styles, while riding bow temples have a curved design that wraps around the ear but do not feature the flexibility of a coil. Thus, comfort cable temples uniquely serve the purpose of comfort through their adaptable and contour-following design.
