With smartphones now being a part of everyone's daily lives, invasions of privacy in areas where people may be more vulnerable are increasingly common – a fact which the LiShield LED light aims to avoid.
The LiShield bulb was designed by researchers at the University of California, San Diego. It was created to block cameras in locker rooms, where cameras and smartphones are usually not allowed, but issues of people taking photos can still occur. The LiShield "can make a room glow for the human eye, but flicker in a distorting light pattern at high frequencies beyond our vision." This ensures that any photos taken under this light sources will feature distorted patterns, and perhaps even colors.
