Model One [Photochromic Radium HD+]

Model One [Photochromic Radium HD+] is a spherical one-piece shield pair of racquet sports protective eyewear built for players who want maximum lens coverage, an uninterrupted field of view, and the versatility to move between indoor, overcast, and sunny conditions without changing lenses.

The Photochromic Radium HD+ lens by ZEISS is a photochromic lens that automatically adjusts its tint based on light conditions — clear indoors and darkening to gray in bright sunlight — making it ideal for players who move between indoor courts, overcast conditions, and full sun without wanting to change lenses. Designed for racquet sports including pickleball, tennis, squash, racquetball, and padel, the Radium HD+ provides 100% UV400 protection in all light conditions. The spherical shield design delivers superior peripheral coverage, wrapping the eye in a single continuous lens that eliminates the frame interruptions and light gaps of traditional two-lens designs. Lenses are made from Impacto, RIA's advanced polycarbonate, for impact safety and optical clarity and surpass the ANSI Z87 impact standard. Lens coatings include anti-moisture, anti-fog, anti-smudge, anti-scratch, and AR Azure (blue-light anti-glare). Lenses are interchangeable and easily replaceable, allowing you to swap to a different HD+ lens as conditions change.

The frame is built from TR-90, a lightweight thermoplastic used throughout the Italian eyewear industry for its durability and comfortable all-day wear. Soft rubber nose and temple pads grip securely without slipping through play.
