Digital free-form lenses are fabricated based on the wearer’s prescription with computer-controlled surfacing equipment that is much more precise than conventional tools. Digital lenses fabrication technology allows for surfacing of lenses in power increments of 0.01 diopter, compared with 0.125 to 0.25 diopter increments possible with traditional eyeglass lens tooling.
