Eyelights target the weaker functioning hemisphere of the brain via the non-dominant eye. With Eyelights therapy, both sides of the brain are being affected, but emphasis is placed on the non-dominant system where dysfunction usually first occurs.

Stimulation of the non-dominant eye will affect the opposite hemisphere of the brain via the thalamus. When stimulating the right eye, the left side or analytical portion of the brain will be affected greater. When stimulating the left eye, the right side or creative portion of the brain will be affected greater.

The lights flash in a monocular pattern with both top and bottom rows flashing at the same time. However, one row will always flash brighter than the other. When the top row of lights is flashing brighter it will affect the temporal lobe (mentality/emotionality) of the brain and parvo cells of the thalamus greater. When the bottom row of lights is flashing brighter it will affect the parietal lobe (sensory/motor) and magno cells of the thalamus greater.
