Nano Vista Xtreme 3.0 NAO3290454 Boys’ Rectangle Eyeglasses in Matte Blue

The Xtreme 3.0 NAO3290454 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. There is a reason NanoVista is recommended by paediatric eye care professionals more than any other children’s eyewear brand: the clinical reality that better-fitting, more comfortable, more durable frames produce better visual outcomes in children. Consistent wear of well-fitting corrective lenses supports normal visual development in ways that intermittent use of uncomfortable or ill-fitting frames cannot. The Siliflex™ material, the ergonomic proportioning for growing faces, and the 3-in-1 fastening system all serve this clinical objective.

The Xtreme 3.0 lives up to its name — a bold, large-format rectangular boys’ collection with the confidence to match the most active and assertive young wearers, built in Siliflex™ for maximum durability. 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.
