Every day, each of us falls under the influence of light. Illuminating devices, ceiling lights at homes and offices, monitor and TV screens create a certain light output, which in theory, should not be harful.
Unfortunately, the theory is often at odds with practice. Invisible to the naked eye, light pulsation can cause very serious health problems. Fatigue, inability to concentrate and permanent internal stress to name a few, are possible signs of irregular light ripples or too much brightness, both of which are hazardous. Sometimes the cause of bad health may not be obvious even if it shines right in your face.
