Cheaper and faster. Waterloo researchers are 3D printing hard contact lenses
University of Waterloo researchers have developed a new technology that uses 3D printing to create custom hard contact lenses in about 20 minutes. Lead researcher Dr. Shirley Tang explains how the innovation could make specialized lenses faster to get and more accessible for people with irregularly shaped corneas.
3D printing breakthrough produces custom contact lenses in 20 minutes
Contact lens technology has come a long way. Early lenses were made from glass, and were uncomfortable to wear for an entire day. Today, lenses are made from soft materials such as silicone hydrogel and they are barely noticeable on the eye.Continue ReadingCategory: 3D Printing, Manufacturing, EngineeringTags: University of Waterloo, Contact Lenses, Vision
A special silicone recipe makes it possible to produce the visual aids with a 3D printer.
