Nano Vista Crew 3.0 NAO3021748SC Boys’ Rectangle Eyeglasses with Sun-Clip in Black/Red

The Crew 3.0 NAO3021748SC 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. This model features a precision-engineered sun-clip that attaches directly to the optical frame, instantly converting prescription eyewear to UV-protective sunwear — ideal for active children who move between indoor and outdoor environments throughout the day. NanoVista approaches children’s eyewear as a paediatric health product first and a fashion item second — and the results justify that priority order. The Siliflex™ material provides the clinical-grade durability and safety. The 3-in-1 fastening system provides the versatility that children’s active lives require. The brand’s extensive, age-appropriate colour range provides the design appeal that helps children embrace wearing their glasses. And the paediatric endorsement that has made NanoVista Spain’s market leader confirms that when you get the health product right, the fashion follows naturally.

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.
