This document provides an overview of important considerations for choosing a fit-over sunglass. It discusses how fit-over eyewear is different from conventional sunglasses in that function is prioritized over fashion. The frame material and design are essential, with malleability and an undercarriage being key characteristics. A soft, flexible material is important for comfort of the "ride" when worn over prescription glasses. The document aims to educate consumers and eyecare professionals on evaluating fit-over sunglasses based on performance characteristics rather than superficial attributes.
