Allen ULTRX Keen Features The Allen ULTRX Keen Youth Safety Glasses are built around a high impact anti-scratch polycarbonate lens that meets the ANSI Z87 rating for genuine eye protection. That certification means the lenses are tested to resist impact rather than simply looking like safety gear which matters when a young shooter is on the line. An anti-fog coating keeps the clear lenses from clouding over in humid or cold conditions so vision stays sharp whether the glasses are used at an indoor range or outdoors in changing weather. The clear lens tint works in any lighting situation making these glasses versatile across shooting workshop and general outdoor use. Padded nose and temple areas are built into the frame to keep the glasses comfortable through extended wear an important detail for youth sized eyewear that needs to stay put during active movement. The Lime Green frame makes the glasses easy to spot in a gear bag or on a crowded range bench a small but practical touch for younger users. Allen designed these as part of the ULTRX line which focuses on combining real safety performance with everyday comfort. For parents and instructors introducing young shooters to the range these glasses are an affordable way to ensure proper eye protection from day one.
