KOO Nova Glasses

The KOO Nova Glasses are a frameless, single-lens cycling sunglass built for riders who want optical clarity and minimal weight without compromising protection. At 21 grams, the Nova sits at the lighter end of performance eyewear present enough to shield your eyes, unobtrusive enough to forget they’re there. Five distinct colorways round out a clean, stripped-back profile that works as well on race day as it does on a long training ride.

KOO developed the Nova’s toric lens in collaboration with Zeiss, meaning the optical geometry is engineered to minimize distortion across the full arc of the lens not just the center. The shatterproof Nylon construction provides 100% UV protection, and a hydrophobic treatment on both the lens and frame helps shed sweat and rain during hard efforts. Flexible temples are designed to handle repeated on-and-off use without losing their shape over time. An interchangeable nose pad system with an Asian fit bridge option included allows the Nova to sit correctly across a range of face shapes rather than defaulting to a single standard fit.

Design Benefits

1. Unobstructed peripheral vision: Removing the frame eliminates the structural interruptions a standard sunglass frame introduces at the edge of your sightline a meaningful advantage when you’re tracking riders in a bunch or navigating technical descents.
2. Zeiss-engineered optics: The toric lens geometry is designed to deliver consistent, distortion-free vision across the entire lens surface, so your view stays accurate whether you’re looking straight ahead or scanning wide.
3. Fit adaptability: The interchangeable nose pad system including an Asian fit bridge means the Nova is designed to stay in place across a wider range of face shapes, reducing the mid-ride slippage that plagues one-size eyewear.
