Nano Vista Xtreme 3.0 NAO3290452 Boys’ Rectangle Eyeglasses in Matte Blue

The Xtreme 3.0 NAO3290452 is a boys’ rectangle frame from the NanoVista collection — built from Siliflex™, the brand’s patented virtually indestructible material, and designed for the real physical demands of active children’s lives. The NanoVista system is more complete than a single frame: it includes the Siliflex™ material, the patented 52° hinge, the 3-in-1 temple/band/mini-band fastening system, and now the NanoFinder AirTag-compatible retainer — a brand ecosystem designed entirely around the practical reality of keeping glasses on children’s faces and in good condition throughout childhood. Spain’s leading children’s eyewear brand did not achieve that position by accident, but by consistently solving the problems that parents and children actually face.

The Xtreme 3.0 lives up to its name — a bold, large-format rectangular boys’ collection with the confidence to match the most active and assertive young wearers, built in Siliflex™ for maximum durability. The rectangular silhouette provides clean horizontal definition that suits a wide range of children’s face shapes, adding the horizontal emphasis that flatters rounder facial geometries while providing a reliable, structured frame for prescription lenses. Available in multiple sizes to accommodate growing faces.
