Health Rounds: 3D-printed contact lenses show promise in early experiments

New tech could let optometrists 3D-print custom rigid contact lenses in about 20 minutes — lab-tested so far and heading toward real-eye trials.
Researchers found a tick-borne nairovirus (PCTNV) on the U.S. West Coast that may evade human immune detection — not yet seen in people but worth watching.
Teams are training computer models to spot risky nairoviruses and boost biosurveillance — a handy reminder to be careful about tick bites and the kinds of ticks you encounter.
