The Vielight 810 is a non-laser intranasal light therapy model. Engineered for gentle brain stimulation. The 810nm near infrared wavelength enables photonic transmission past the intranasal channel to the deep ventral brain areas. Neurons are well-suited for photobiomodulation because they contain mitochondria. Before and after QEEG images show the Vielight 810 inducing restorative activity in the brain per 25-minute session. The intranasal devices combine solid state technology along with intranasal diodes built from transparent high impact polycarbonate to ensure quality and durability, turning this into a lifetime investment.
