The Epic glasses are part of Wiley X's WorkSight series with side shields for protection. These WorkSight side shields are removable so you can wear the Epic as daily glasses. Shatterproof lenses meet ANSI Z87.1-2018 safety standards, and the T-Shell lens coating resists scratching. Flexible Triloid nylon frame and adjustable wire core temple tips provide the most comfort. Keep your eyes protected inside and outside of your workplace by getting the Wiley X Epic in prescription from SportRx.
