The Sferoflex SF1143 eyeglasses offer a sleek, streamlined design to complement any wardrobe. The universally flattering rectangular frames feature a softly curved browline and squared-off endpoints for a geek-chic, masculine silhouette. The SF1143 rims come in sturdy, hypoallergenic acetate, and the slim temples are made in non-corrosive metal for contrast. The metal temples wrap around to the endpoints, adding interest to the wingtips, and a slim metal line from the hinge to the coated temple tips refines the style. The patented Sferoflex spring hinges offer a balanced fit. Update your wardrobe and opt for elevated style wearing the SF1143 eyeglasses from Sferoflex.
