If you have irregularly shaped corneas or a vision condition that requires hard contact lenses -- such as severe nearsightedness, farsightedness or astigmatism -- you know that finding the right fit can take weeks of trial and error. That could all change with 3D-printed contact lenses that take under 20 minutes to produce.
A press release published on Tuesday reports that researchers at the University of Waterloo's Department of Chemistry in Ontario, Canada, have developed a contact lens system that uses custom software to digitally map each patient's cornea, i.e., the clear, dome-shaped outer layer that covers the front of the eye.
Instead of relying on premanufactured lenses in set sizes, the platform would create personalized lenses that conform to your cornea's shape and size with a rapid production...
