So the tyndal effect can be very faint and may require a darkened room and the intensity of the laser pointer to reveal it. Faith: I have a couple of laser pointers and they are indeed very bright. You simply do not point them at anyone's face or look into the beam. If you get a glint of the light off a reflective surface just look away and/or move the beam. It will not instantly blind you or cause any damage at all unless you go out of your way to be foolish with it. It's worth realizing that any risk associated with a laser pointer is one that's entirely under your control. I think you can be trusted to use one safely! Be well, Mike D.
