Today is only my 3rd day wearing my 3-in-1 and I've already noticed that my last 2 nights of sleep have been much better. I don't usually have trouble sleeping, but I do work extensive hours on a computer. Using these glasses so far have changed my good nights of sleep to great nights of sleep. My recorded deep cycle on my wearable device have practically doubled. I hope this isn't just a coincidence, but usage over time will tell.
