Solid flowing contours that conform to most face types are just the start of the benefits offered by Foster Grant® IRONMAN® Sprint reading glasses for men. That substantial black frame encloses rectangular lenses built for long-term clarity. How? By adding a hard, protective clear coating to the surfaces, these lenses resist the scratches and impact that everyday use can bring. The frame is also made of a superior, shock-absorbing flexible material that imparts durability, comfort, and fit. Foster Grant IRONMAN Sprint readers accommodate most vision needs too by offering a broad range of lens powers. Wherever you're reading or viewing, you can take your Foster Grant IRONMAN Sprint readers with you in the included soft-shell travel/storage case.
