What is Blue Light?

Wave lengths of Blue Light are between 380nm and 495 nm in the range of visible lights (from 400nm to 780nm).  BlueLight has strong energy with very short waves, very close to the wave length of UV-A light. Blue Light is widely used as the light source to produce crisp images in the LED light sourced products such as PCs, Cell Phones, Tablets, Game machines and TVs.

The vitreous body and the crystalline lenses in the eye absorb UV lights but Blue Light reaches the retina with strong energy. The impact of Blue Light is believed to cause eye fatigue and may even cause age-related macular degeneration, according to some experts.

A prolonged exposure of the eye to Blue Light is believed to cause health hazard that is now called Blue Light Hazard, as many media report.
