Fashion-forward bold look, featherlight feel.
The Square-D is an avant-garde statement frame for teens and adults who like their eyewear to say something. Inspired by the playful paper cut-outs of modern art, its angled, polygonal frame is sculpted like shapes snipped from colored paper, a design that celebrates bold creativity. It comes in a curated palette of stylish, timeless colors and has a premium matte soft-touch finish. It also comes in kids' and youth sizes, so the whole family can wear matching frames. Each pair arrives as a gift set with a silk scarf and a protective carry case with a keychain snap ring. The look is big, but the weight isn't: the Swiss TR90 frame weighs just 28 g, flexes under pressure and springs back into shape. Polarized UV400 lenses keep your eyes comfortable, from city streets to the coast.
What is TR90, and why does it matter?
TR90 is a lightweight, flexible frame material first developed in Switzerland. Many premium sports and lifestyle eyewear brands use it. For you, that means:
- Feather-light. TR90 weighs about half as much as traditional acetate frames, so you feel less pressure on your nose and ears, even after a full day of wear.
- Bends instead of breaking. It's flexible and impact-resistant, so it bends under stress and pops back into shape. It survives being tossed in a bag or sat on.
- Gentle on skin. It's hypoallergenic, BPA-free and metal-free, so it's safe for sensitive skin. 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 dashboard or a long beach day.
- Soft-touch matte finish. Its smooth, velvety texture feels refined in the hand and grips better than glossy acetate.
Why you'll love them
- Iconic sculpted silhouette: The angled, polygonal frame makes a confident, fashion-forward statement that stands apart from everyday sunglasses.
- Made for bold creativity: The design is part wearable art and part accessory, and it suits anyone who dresses to express themselves. Style it with the included silk scarf.
- Stylish, timeless colors: Refined shades that pair easily with any wardrobe, season after season.
- Matching family style: The same Square-D design comes in Kids (3–7) and Youth (7–12) sizes, for matching looks with your little ones.
- 100% UV protection (UV400): Blocks 100% of UVA and UVB rays up to 400 nm.
- 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.
- Built to last: The lenses are impact-resistant and meet the FDA impact requirement for sunglasses.
- Stainless steel spring hinges: The arms flex outward for a secure, comfortable fit on a range of face shapes.
- Curved temples: The arms wrap gently around the ears, so the glasses stay put without pinching.
- Temple end rings: Rubber rings on the arm tips let you attach a strap.
- Clip-on carry case: A keychain snap ring lets the case clip onto a bag, backpack or belt loop, so your 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."

Care instructions
• Rinse under fresh running water, then wipe dry with the included rPET microfiber cloth.

• Don't use paper towels, clothing or household cleaners on the lenses.
• Store in the included protective case when not in use.
REVO (mirrored) lens care
Reflective REVO coatings need a little extra care:

• Keep away from harsh chemicals, including alcohol, hand sanitizer, sunscreen and insect repellent.
• Rinse right away after pool, sea or sunscreen exposure. Never wipe a dry, salty or sandy lens.
