I am going to be overly cautious and use eye protection even so. It is easy enough, why not. But LEDs are vastly safer than lasers for the eyes, so much better off regardless.
You can definitely overdo it, that is the tricky thing about LLLT, you need enough but not too much. But we are all guessing what is the just right amount. My plan is to follow the protocol
@Bobby B has mentioned, along the lines of 5 or so minutes per ear 2 or 3 times a week. And additional 5 minute applications for other areas (like behind the ear, the jaw, etc.). This protocol is also roughly similar to what Red Light Man suggests for tinnitus.
