Energy Safety Issues
Vielight 633 Red
The Vielight 633 Red emits non-laser based irradiation (incoherent light) with a low level energy intensity.
Vielight 655 Prime
The Vielight 655 Prime emits laser based irradiation that is designed to generate very low and safe energy output.
However pointing a laser light to the retina can cause tissue damage and scarring. The danger of this is mitigated by the fact that the Vielight 655 laser does not emit a pure, collimated laser: the light is not completely coherent and has some built-in divergence of about 57 degrees. Human involuntary reflex would also cause immediate blinking when the laser light is pointed to the eye. Nevertheless, precaution should still always be taken and it should not be handled by children without supervision.
Vielight 810 Infrared
The Vielight 810 Infrared emits non-laser based irradiation (incoherent light) with a low level energy intensity. Users should note that light within this electromagnetic range is invisible to the naked eye.
