Vive’s patented nanofilter technology has been independently verified to filter out harmful wavelengths and only transmit human-safe 222nm light. This 222nm light cannot penetrate the top layer of human skin or the tear layer of the eye, making Vive completely safe for use in occupied spaces. In fact, studies show that 10 minutes of exposure to sunlight causes more damage than 30,000 hours of exposure to Vive’s filtered far-UV.
