Regarding VIELIGHT and other Light and Laser Products
After more than three decades of research there are no known major side effects attached to these light therapies.
Reported Side Effects for First-Time Users
  • Tiredness (temporary) – probably due to the release of metabolites but the majority report a resurgence of energy
  • Headaches (temporary) – from the reactivation of neural connections and increased microcirculation
  • Dry throat (temporary) – from the stimulation of renal functions
Over 40 years of accumulated scientific studies on low level light therapy reveal no major contraindication. However, we at Health Smart Technology like to err on the side of caustion and suggest the same contrainfdications as seen under PEMF contraindications below.
Energy Safety Issues
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.
PEMF Products
As with Light and laser products the folowing Reported side effects have been reported usually by people that do not drink enough fluid pre and post use of the device, adn simply drinking more fluid can help avoid any symptoms
  • Tiredness
  • Slight headaches
  • Achy feeling
  • Mild cold /flu like symptomes
Unlike with light and laser products there are some contraindications with PEMF Therapy.
  • Who are under the age of 18 (or of legal age, depending on location) without written parental
  • guardian consent
  • Who have a pacemaker or other electronic implanted device
  • Who is pregnant
  • Who has been diagnosed with Epliepsy or other seizure related disorders
  • Who has been diagnosed with Cancer or other life threatening illnesses/diseases
  • Who has had majory surgery in the past 24 hours
  • Who is actively bleeding
