These Trekker men's reading glasses are part of the Foster Grant® IRONMAN® collection. They offer the strong performance and design smarts you expect from the IRONMAN® brand. Medium-thick black temples merge into gunmetal-colored frames for an understated look. These glasses are designed to be lightweight and rest easily on most faces enabling long periods of wear without fatigue. The large rectangular lenses provide plenty of viewing area and are available in a wide range of lens powers. The lenses are surfaced with a protective coating that resists scratches and impact so say goodbye to annoying surface blemishes.
