The Nike 4644 prescription eyeglasses combine performance-driven design with Flexon memory metal technology for exceptional durability and all-day comfort. Built for active lifestyles, these full-rim rectangular frames feature a stainless steel construction enhanced with Flexon memory metal at the bridge—a titanium-nickel alloy that can bend, flex, and twist under pressure, then return to its original shape without damage.
Available in three sporty color combinations—Matte Black with Total Orange accents, Satin Gunmetal with Vintage Green temples, and Matte Midnight Navy with Silver detailing—the Nike 4644 brings athletic style to everyday eyewear. The iconic Nike swoosh logo appears on each temple in a contrasting color, adding brand recognition without being excessive. Two lens sizes (48mm and 50mm) accommodate kids, teens, and adults with smaller face widths, while the 16mm bridge and 135mm temples provide a balanced, secure fit.
Adjustable silicone nose pads let you customize the fit to prevent slipping during movement, and the full-rim design provides maximum lens stability—making these frames compatible with single-vision, progressive, and bifocal prescription lenses. The lightweight metal construction won’t weigh you down during extended wear, whether you’re at school, work, or on the field. These prescription-ready frames ship with demo lenses that can be replaced with your custom prescription by our licensed opticians.
Flexon memory metal has been the gold standard in durable eyewear since 1988, originally developed from aerospace materials. The technology allows the Nike 4644 to withstand the demands of active daily use—accidental bending, drops, and the rough-and-tumble of sports and play—while maintaining its shape and structural integrity. For parents seeking reliable eyewear for kids, or adults who need frames that keep up with an active routine, the memory metal construction delivers peace of mind and long-term value.
