Lens Crafter II

Short answer: To fit glasses, an optician uses an edger machine that traces the specific frame, then grinds the prescription lens blank down to that shape, adjusting for the material; some lenses need specialized tools. The footage, credited to Eurekahnb, shows lenses being cut and ground in an edger.
