Nano Vista Crew 3.0 NAO3020446 Kids’ Rectangle Eyeglasses in Black/Green

The Crew 3.0 NAO3020446 is a kids’ 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. Parents trust NanoVista because it consistently delivers on its core promise: glasses that survive childhood. The Siliflex™ material — patented, BPA-free, heat-moldable, and completely metal-free — is the technical foundation of that promise. The 52° hinge that provides 180° rotation without breakage is its mechanical expression. The 3-in-1 fastening system is its practical application to daily life. And the brand’s position as Spain’s number-one children’s optical brand, endorsed by paediatricians and ophthalmologists worldwide, is its market validation. These are glasses built to last.

The Crew 3.0 is one of NanoVista’s widest-ranging collections — covering boys’, girls’, and unisex options in rectangular silhouettes across a broad palette of bold bicolour combinations, with sun-clip variants also available. 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.
