THE DELTA SERIES

The Delta frame uses a teardrop shape specifically to help block side light from entering behind the mask of the glasses. This is a critical design element that helps relax the eye, extending visual endurance over the course of a match. When the eye is relaxed, it can take full advantage of the filter technology infused into the lens. This
design is highly effective in maintaining the eyes in an “active” state, which helps keep hand–eye coordination fresh, quick, and precise. The wider design also helps in windy conditions and reduces dust intrusion.

Equipped with a soft, durable rubber sweat bar, this feature increases airflow behind the lens to help prevent fogging during intense activity. It channels heat and moisture away from the eyes, keeping your vision clear. Paired with our ZEISS “Ice” lens coating, the sweat bar contributes to excellent fog and steaming reduction —even in hot or humid conditions.

The single saddle nosepiece is made from high-performance silicone, providing a cushioned and secure fit across the bridge of the nose. It’s designed to stay in place during quick head turns, sprints, and active play, offering all-day comfort without slipping or pinching; even during high-sweat, high-impact movement.

Every lens features advanced ZEISS “ICE” technology, combining Chromashift and Infra Red filtration to deliver sharp contrast, enhanced color, and improved clarity across a wide range of lighting conditions, both indoors and outdoors. All lenses are treated with ZEISS’s 7-layer anti-reflective coating to eliminate glare, reduce eye strain, and meet ZEISS’s rigorous optical certification standards for peak visual performance. 

Change lens filters quickly and with ease. The Delta System uses a proprietary Pilla design that has been part of our technology for over 25 years. The frame snaps off the lens by releasing the side snaps and center pin. Attaching the frame to a new lens filter is just as simple: the center of the frame hinge slides under the center pin, and the hinge snaps securely into the top and bottom catches. This design allows athletes to change lenses easily without leaving fingerprints on the optics.
