With free-form lenses (also called digital high-definition lenses), the fabrication of the lenses from wearer's eyeglass prescription is optimized with computer-controlled surfacing equipment that is much more precise than conventional tools.

Many of the techniques developed for medical imaging also have scientific and industrial applications. Medical imaging is often perceived to designate the set of techniques that noninvasively produce images of the internal aspect of the body.In this restricted sense, medical imaging can be seen as the solution of mathematical inverse problems.edical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention.
