A company in China has developed heat-detecting glasses that can "see" people’s temperatures up to 10 feet away. The glasses employ an infrared thermometer to detect temperatures. That data is then sent to the glasses, where the temperatures can be visualized. The shades could be used to help screen for cases of COVID-19, though they also raise privacy concerns. The technology is drawing comparisons to the "Terminator" and "Predator" movies.
