I have a pair of glasses with leds that pulsate light at different frequencies following a programmed routine on an arduino chip. You, of course, use it with eyes closed. First time I used it I felt pretty bad, but there was something intriguing going on. I tried it again the next day and it was amazing. It induces a state of very deep relaxation. As the routine progresses you get more and more relaxed. Your mind really changes from an alert alpha frequency, to a delta or theta frequency. At the end of it I feel like I did a session of deep meditation with mantras. So yes, this really does work.
