Nano Vista Sonic 3.0 NAO3310452 Boys’ Rectangle Eyeglasses in Matte Black

The Sonic 3.0 NAO3310452 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 moment a parent discovers NanoVista, a specific kind of relief sets in — the recognition that the cycle of broken frames, emergency repairs, and frequent replacements does not have to continue. Built from Siliflex™, the brand’s patented ultra-flexible material, every NanoVista frame is engineered from the ground up for the reality of children’s lives: the drops, the bends, the sat-upon moments, the sports sessions, and everything else that a pair of glasses worn by an active child will encounter.

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.
