Nano Vista Xtreme 3.0 NAO3290252 Boys’ Rectangle Eyeglasses in Black

The Xtreme 3.0 NAO3290252 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 founded on a recognition that the conventional prescription glasses model does not work well for children. Frames that are not designed specifically for children’s face geometries fit poorly and slip constantly. Metal frames carry injury and allergy risks. Standard acetate breaks under the physical demands of active play. The Siliflex™ material addresses all of these limitations simultaneously — and in doing so created the foundation of Spain’s best-selling children’s eyewear brand, recommended by the paediatric eye care community worldwide.

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.
