Lew Lim and his colleagues invented intranasal light therapy (or “photobiomodulation”) as a non-invasive method to introduce therapeutic photonic energy into the human body in California in 1995. The research and development continued under MedicLights Research Inc in the 2000’s before Vielight Inc was founded to commercialize the invention. The research data in the field of photomedicine is growing and promising. However, photomedicine requires science combined with engineering creativity to make it accessible for use in everyday life.
