For comfortable eyewear with classic style, choose the SF2203 eyeglasses from Sferoflex. Enjoy the minimalist look of these semi-rimless frames, and know that despite their unassuming presence, they’re exceptionally sturdy—Sferoflex crafts these frames in steel. Sferoflex glasses are named after the company’s original, patented spring hinge—a flexible design that provides a comfortable fit, neither too snug nor too loose. In the Sferoflex SF2203, an alternate fit ensures comfort for the wearer with high cheekbones or a low or wide nose bridge.
