Nano Vista Sonic 3.0 NAO3310450 Boys’ Rectangle Eyeglasses in Matte Black

The Sonic 3.0 NAO3310450 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. NanoVista built its reputation — and its position as Spain’s number-one children’s eyewear brand — on a single founding insight: children need glasses that can keep up with them, not glasses that impose limitations on how they move through the world. The Siliflex™ material that forms the core of the NanoVista system is the technical answer to that insight: a patented, BPA-free thermoplastic that bends rather than breaks, returns to its original shape, and contains no metal parts that could cause injury or irritation.

The Sonic 3.0 is a clean rectangular boys’ collection — offering confident proportions and a bold colour palette in NanoVista’s characteristic metal-free Siliflex™ construction, available in multiple sizes. 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.
