The DB4K React MISCHIEVOUS eyeglasses bring together everything parents need in kids' prescription frames: flexibility that survives rough play, eco-friendly materials, and a square shape that kids actually want to wear. Available in sizes 47 and 49mm with a 17mm bridge, these unisex frames work for school, sports, and everything in between. Built from Award-Winning Pebax® Rnew® Material These frames are made from Pebax® Rnew®, a bio-based material derived from castor beans that absorb atmospheric CO2 while they grow. The result is a frame that's BPA-free, latex-free, and hypoallergenic—safe for sensitive skin and kind to the planet. The material is strong yet flexible enough to bend and twist without breaking, which means fewer emergency replacements when your child sits on their glasses or tosses them in a backpack. DB4K React earned recognition as one of Fast Company's World Changing Ideas for good reason. The Pebax® Rnew® construction can be heated by opticians for precise lens insertion and adjustments, making these frames as practical for your eye care professional as they are durable for your child. The signature fused React crinkle hinge combines strength, flexibility, and comfort without traditional screws that loosen or break. Designed for Active Kids The MISCHIEVOUS features ergonomic temples that hug the head to keep glasses in place during play and sports. Each frame includes a color-coordinated removable strap for extra security—perfect for younger children, high-energy activities, or kids who need that added confidence their glasses won't fly off. The full-rim acetate construction provides excellent lens support and durability. These frames are fully prescription-ready and compatible with single vision, bifocal, and progressive lenses. Pair them with impact-resistant polycarbonate or Trivex lenses for maximum protection during active wear. The square shape offers generous lens area for better peripheral vision, and the lightweight build means kids can wear them comfortably all day without pressure points on the nose or ears. Available in three two-tone color options—Khaki Fade/Black, Sky/Gray, and Black/Red—the MISCHIEVOUS lets kids express their personality without relying on cartoon characters. DB4K's mission is simple: make glasses kids want to wear. The translucent fade finishes and bold color combinations deliver on that promise.
