Photic light stimulation
WebPhotic mind machines work with flickering lights embedded in sunglasses or a lamp that sits above or facing the user's head. The user then "watches" with their eyes closed. [citation needed] The process applied by some of these machines is said to induce brainwave synchronisation or entrainment.
