Nano Vista Birdie 3.0 NAO4020338 Girls’ Round Eyeglasses in Light Blue

The Birdie 3.0 NAO4020338 is a girls’ round 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’s ‘3 glasses in 1’ system is genuinely practical: the interchangeable temple/band/mini-band configuration means a single frame can adapt from a standard school-day setup to an active sports configuration to a secure band for more physical activity — without purchasing a second frame. Combined with the virtually indestructible Siliflex™ construction and the brand’s complete absence of metal parts, the result is a children’s optical frame that is genuinely designed for the full range of a child’s daily life rather than just the well-behaved portion of it.

The Birdie 3.0 is designed for younger children — its compact proportions, gentle round silhouette, and cheerful colour palette make it one of the most popular NanoVista choices for the earliest years of prescription eyewear. The round silhouette provides a universally flattering circular geometry that works beautifully on most children’s face shapes, softening angular features and adding a contemporary, classic quality to the frame. Available in multiple sizes for precise fitting.
