Fashion-forward bold look, featherlight feel.
The Square-D is a bold, avant-garde take on kids' eyewear that's light enough to wear all day. Inspired by the playful paper cut-outs of modern art, its angled, polygonal frame is sculpted like shapes snipped from colored paper, made for kids who celebrate bold creativity and aren't afraid to express it. It comes in a curated palette of stylish, timeless colors and has a premium matte soft-touch finish. Each pair arrives as a complete gift set with a silk scarf, a protective carry case with a keychain snap ring, and two charms. The look is big, but the weight isn't: the ultra-light Swiss TR90 frame weighs just 21 g, and it bends under pressure and springs back into shape, so it's built for real kid life. Polarized UV400 lenses protect your child's eyes from city streets to beach days.
What is TR90, and why does it matter?
TR90 is a lightweight, flexible frame material first developed in Switzerland. Many premium sports and kids' eyewear brands use it. For your child, that means:
- Feather-light. TR90 weighs about half as much as traditional acetate frames, so there's less pressure on the nose and ears. They're so light kids forget they're wearing them.
- Bends instead of breaking. It's flexible and impact-resistant, so it bends under stress and pops back into shape. That's why it's a top choice for sports eyewear, active adults and kids.
- Gentle on skin. It's hypoallergenic, BPA-free and metal-free, so it's safe for sensitive skin and metal allergies. There's no paint coating to chip or flake.
- Holds up to real life. It resists sweat, skin oils, sunscreen and heat better than standard plastics, so it won't warp or fade on a hot car dashboard or a long beach day.
- Soft-touch matte finish. TR90 has a smooth, rubber-like matte texture instead of the high-gloss shine of acetate. It's comfortable to hold and less slippery in little hands.
Why parents love them
- Iconic sculpted silhouette: The angled, polygonal Square-D frame makes a confident, fashion-forward statement and stands apart from ordinary kids' sunglasses.
- Made for bold creativity: A design that celebrates self-expression. Kids can style it with the silk scarf and add personality with the charms.
- Stylish, timeless colors: Refined shades that pair easily with any outfit, season after season.
- Premium matte soft-touch finish: Smooth and velvety in the hand. It isn't slippery or shiny, and it hides fingerprints and small scuffs better than glossy frames.
- 100% UV protection (UV400): Blocks 100% of UVA and UVB rays up to 400 nm. Children's eyes let in more UV than adult eyes, so this matters most.
- Polarized TAC lenses: Cut glare off water, sand, snow and pavement for crisp, clear vision.
- Category 3 lenses: Made for bright, sunny days. They let through only 8–18% of visible light.
- Bend-and-flex Swiss TR90 frame: Ultra-light and flexible enough to handle everyday kid life.
- Built for drops and tumbles: The lenses are impact-resistant and meet the FDA impact requirement for sunglasses.
- Stainless steel spring hinges: The arms flex outward, so the glasses survive being yanked on and off and keep a secure fit as faces grow.
- Curved temples for a comfortable fit: The arms wrap gently around the ears, so the glasses stay put without pinching.
- Temple end rings: Rubber rings on the arm tips hold the included charms or a strap.
- Clip-on carry case: A keychain snap ring lets the case clip onto a backpack, beach bag or belt loop, so the sunglasses are always within reach.

How to measure face width
- Have your child look straight ahead with a relaxed face.
- Hold a ruler or soft tape measure horizontally across the eyes.
- Measure from one temple to the other (the flat spots just outside the eyes, in front of the ears).
- Compare the number in millimeters with the "Fits face width" range for each size.
No ruler handy? Measure the front of a pair of glasses that already fits well, from hinge to hinge.
Reading the frame size
Frame sizes are written like 48□20-139: a 48 mm lens width, a 20 mm bridge (the gap between the lenses over the nose) and 139 mm temple arms. Every product page lists these under "Size & specs."
