The Nanovista POWER UP 3.0-NAO308 Eyeglasses are built for kids who don't slow down. These square-frame prescription eyeglasses feature the brand's patented SILIFLEX material—a flexible, hypoallergenic construction that bends without breaking and weighs 35% less than traditional acetate frames. Available in vibrant two-tone color combinations like matte blue/green and black/blue (as shown), the POWER UP 3.0 brings durability and style together in a frame designed specifically for active children.
Virtually Indestructible Frame Technology
Parents know the struggle: kids run, jump, sit on their glasses, and toss them in backpacks. The POWER UP 3.0 solves this with SILIFLEX, a heat-moldable, non-toxic material that's BPA-free and built to withstand the daily chaos of childhood. The improved 3.0 hinge design allows for greater flexibility and range of motion without breakage, while soft rubber temple tips and nose pads ensure all-day comfort. These frames are prescription-ready and compatible with single vision, bifocal, and progressive lenses in polycarbonate, Trivex, and high-index materials.
Adaptable for Any Activity
What sets the POWER UP 3.0 apart is its versatility. Each frame includes interchangeable temple arms plus an adjustable strap and mini-strap, so kids can switch from classroom mode to playground mode in seconds. The full-rim square design fits faces comfortably in two sizes (48mm and 50mm lens width), with a 15mm bridge and 132mm temple length. No metal parts mean safer wear for younger children, and the hypoallergenic construction is gentle on sensitive skin.
Nanovista is the leading children's eyewear brand in Spain and is recommended by pediatricians and ophthalmologists worldwide. The POWER UP 3.0 represents the brand's commitment to creating glasses that kids will actually wear—because when glasses are comfortable, lightweight, and tough enough to keep up, children are far more likely to keep them on.

Frequently Asked Questions
Are Nanovista POWER UP 3.0 eyeglasses really unbreakable?
While no frame is completely indestructible, the POWER UP 3.0 is made from patented SILIFLEX material that's designed to bend and flex without breaking. The frames can withstand twisting, dropping, and the rough handling typical of active kids. The improved 3.0 hinge design allows 180-degree rotation without snapping, making these frames significantly more durable than traditional plastic or metal frames.
What age range are these glasses designed for?
The Nanovista POWER UP 3.0 is designed for children ages 4-10, available in two sizes: 48mm and 50mm lens width. The square frame shape with a 15mm bridge and 132mm temples fits most kids in this age range. The adjustable temple tips and interchangeable strap system help ensure a secure, comfortable fit as your child grows.
Can I add prescription lenses to these frames?
Yes, the POWER UP 3.0 frames are fully prescription-ready. They're compatible with single vision, bifocal, and progressive lenses. You can choose from polycarbonate (recommended for kids due to impact resistance), Trivex, or high-index lens materials. The frames can also accommodate blue light filtering, anti-reflective coatings, and photochromic (Transitions) lenses.
What is SILIFLEX material and is it safe for children?
SILIFLEX is Nanovista's patented, heat-moldable thermoplastic material that's hypoallergenic, non-toxic, and BPA-free. It's 35% lighter than traditional acetate frames and provides exceptional flexibility and durability. The material is specifically designed for children's eyewear and meets pediatric safety standards. It contains no metal parts, reducing injury risk during active play.
How do the interchangeable straps work?
Each POWER UP 3.0 frame includes three wearing options: traditional temple arms, an adjustable elastic strap, and a mini-strap. You can easily swap between temples and straps depending on your child's activity—use temples for everyday wear and switch to the strap for sports, playground time, or younger children who need extra security. The soft rubber temple tips are manually adjustable for a custom fit.
Why are flexible frames better than regular frames for kids?
Flexible frames like the POWER UP 3.0 bend instead of breaking when dropped, twisted, or sat on—common occurrences with active children. Studies show flexible frames can last 2-5 times longer than traditional rigid frames, reducing replacement costs. They're also more comfortable because they naturally adjust to a child's face shape, eliminating pressure points and making kids more likely to wear their glasses consistently.

Nanovista POWER UP 3.0 vs. Similar Kids' Eyeglasses
Choosing the right eyeglasses for your child means balancing durability, comfort, and style. Here's how the POWER UP 3.0 compares to other popular options in our collection.
POWER UP 3.0 vs. Nanovista GAIKAI 3.0
Both frames share the same virtually indestructible SILIFLEX construction and 3.0 technology upgrades, including improved hinges and interchangeable strap systems. The main difference is frame shape: the POWER UP features a classic square design, while the GAIKAI offers a different silhouette. Both are priced similarly ($94-$133) and fit the same age range. If your child has tried one Nanovista 3.0 model and loved the feel, any other 3.0 frame will deliver the same durability and comfort—just pick the shape your child prefers.
POWER UP 3.0 vs. Nanovista SLEEK REPLAY 3.0
The SLEEK REPLAY 3.0 is another excellent option within the Nanovista family, featuring the same flexible, lightweight SILIFLEX material and dual temple/strap system. At $96-$98, it's priced nearly identically to the POWER UP 3.0. The choice comes down to frame aesthetics and which style your child gravitates toward. Both offer the same prescription compatibility and are built to withstand active play.
POWER UP 3.0 vs. Ray-Ban Kids 0RY1586
This comparison highlights two different philosophies in children's eyewear. Ray-Ban Junior frames ($48-$98) offer iconic brand styling and traditional construction at a lower entry price. However, they use rigid frame materials that are more susceptible to breakage when dropped or twisted. The POWER UP 3.0 costs slightly more but delivers specialized features designed specifically for active kids: flexible SILIFLEX material that's 35% lighter, interchangeable straps for sports and play, and construction that bends instead of breaking. For parents who've replaced broken frames multiple times, the POWER UP 3.0's durability often saves money in the long run. If your child is gentle with glasses and prefers classic styling, Ray-Ban Junior is a solid choice. If your child is active, rough on frames, or needs glasses that can transition from classroom to playground, the POWER UP 3.0 is the better investment.
Our recommendation: The Nanovista POWER UP 3.0 offers the best combination of durability, comfort, and versatility for active children. The flexible SILIFLEX construction, interchangeable strap system, and lightweight design make these frames ideal for kids who need glasses that can truly keep up with their lifestyle.
