The Science


Photobiology is the study of the effects of non-ionizing radiation on biological systems. The biological effect varies with the wavelength region of the radiation.

Biological reaction to light is nothing new, there are numerous examples of light induced photochemical reactions in biological systems. Vitamin D synthesis in our skin is an example of a photochemical reaction. The power density of sunlight is only 105 mW/cm2 yet when ultraviolet B (UVB) rays strikes our skin, it converts a universally present form of cholesterol, 7-dehydrocholesterol to vitamin D3. We normally experience this through our eyes which are obviously photosensitive – our vision is based upon light hitting our retinas and creating a chemical reaction that allows us to see. Throughout the course of evolution, photons have played a vital role in photo-chemically energizing certain cells.


At the cellular level, visible red and near infrared light energy stimulates cells to generate more energy and promote optimal functioning. Each cell has mitochondria, which perform the function of producing cellular energy called “ATP”. This production process involves the respiratory chain. A mitochondrial enzyme called cytochrome oxidase c then accepts photonic energy, promoting enhanced ATP production.


Low level visible red to near infrared light energy is absorbed by mitochondria and converted into ATP for cellular use. In addition, the process creates reactive oxygen species (ROS) that leads to gene transcription. The process also enhances ATP production by releasing nitric oxide from the mitochondrial enzyme cytochrome c oxidase [1] The released nitric oxide can then activate a number of beneficial cellular pathways [2].

The basis of all our thoughts, behaviour and emotions is the interaction between neuronal networks communicating with each other. This interaction leads to the formation of neural electrical signals known as brainwaves.

Brain photobiomodulation stimulates neuronal mitochondria, which increases celullar energy levels. This results in improved efficiency in neural signalling and communication.

Vielight technology is the first in the world to demonstrate the ability to modulate and alter brainwaves using NIR electromagnetic (light) energy, measured through EEG.

  • Alpha brainwaves are prominent when the mind is calm and in some meditative states. Alpha is the resting state for the brain.

    Alpha waves help with developing overall mental coordination, calmness and inner peace.

    Initial EEG testing indicates that the Vielight Neuro Alpha’s 10 Hz pulse can elevate neural Alpha waves.

  • Gamma brainwaves are prominent when the mind is attentive and in the process of learning. Gamma is the active state of the brain.

    When Gamma oscillations are elevated, this leads to increased focus, learning and memory consolidation.

    Initial EEG testing indicates that the Vielight Neuro Gamma’s 40 Hz pulse can elevate neural Gamma waves.

Our science division is committed to furthering research in the field of neuromodulation using NIR light for the benefit of everyone.

Figure : Influence of tPBM on resting-state electroencephalography. Box plot illustrates the median and range of power spectrum across all electrodes for each oscillatory frequency bands. (a) Effect of active tPBM on power spectrum pre (green line) and post (red line). (b) Effect of sham tPBM on power spectrum pre (green line) and post (red line). (c) Difference between Active and Sham tPBM: Change of power spectrum Post-Pre for active (red line) and sham (green line) tPBM. Active versus sham stimulation revealed significant lower alteration in delta and theta power and higher change in alpha, beta and gamma frequency bands.
