Nano Vista Crew 3.0 NAO3021848 Boys’ Rectangle Eyeglasses in Black/Green

The Crew 3.0 NAO3021848 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 was built on a parent’s understanding of what makes children’s eyewear genuinely stressful: not the cost of the initial frame, but the frequency of replacement, the emergency trips to the optician, and the ongoing anxiety about whether the next pair will survive any longer than the last. The Siliflex™ material addresses this stress at its source — a virtually indestructible, BPA-free, hypoallergenic thermoplastic that bends without breaking and is endorsed by the paediatric eye care community as the standard of excellence in children’s prescription eyewear.

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.
