At eyebobs, "Biff" refers to the striking fashionableness and versatility of our classic readers. So when you hear us say, "They really Biffed it," we're not referring to some sort of squabble – unless it's a squabble over how on point these readers are. This classic eyebobs frame was formerly named "Butch." Our Biff reader lenses are scratch-resistant and smudge-proof, and are available in diopters ranging from 0.00 to +4.00. Translation: no matter what your reader strength is or how hard you are on your glasses, you can get Biffed.
