Maybe your comment is correct in whole, but your examples immediately brought to mind science headlines from the past few years. Specifically the use of Near InfraRed (NIR) light to treat Multiple Sclerosis, the use of blue light to heal wounds and disinfect, reading the states of neurons in hydra and also in mice, implanting false memories into mice, and a plethora of transportable medical scanners. The implementation is not what a viewer would imagine, but they all meet the descriptions as written. Even if we are not near, we are undoubtedly approaching "Star Trek" technology by so narrowly attempting to replicate it. https://www.sciencedaily.com/releases/2013/10/131022102227.htm https://www.sciencedaily.com/releases/2013/10/131022102227.h... https://www.sciencedaily.com/releases/2013/09/130910142334.htm https://www.sciencedaily.com/releases/2013/09/130910142334.h... http://www.dailytech.com/New+Miracle+Diagnosis+Handheld+Medical+Scanner+800+Times+More+Sensitive+Than+Fullsize+Scanners/article12322.htm http://www.dailytech.com/New+Miracle+Diagnosis+Handheld+Medi... https://www.cnet.com/news/esight-video-glasses-restores-sight-legally-blind-star-trek-visor-headset/ https://www.cnet.com/news/esight-video-glasses-restores-sigh... https://www.theguardian.com/science/2010/nov/03/vision-chip-sight-blind-man https://www.theguardian.com/science/2010/nov/03/vision-chip-...
