Far-UVC light cannot penetrate the tear layer of the eye or the outer dead-cell layer of skin and so it cannot reach or damage living cells in the body. https://www.cuimc.columbia.edu/news/far-uvc-light-safely-kills-airborne-coronaviruses https://www.cuimc.columbia.edu/news/far-uvc-light-safely-kil...
