This national public education campaign is designed to increase awareness among parents of children ages 8 to 12 about the causes and prevention of noise-induced hearing loss.
Our eyes are what allow us to see. Our eyes are designed to detect a small portion of the electromagnetic spectrum. This part of the spectrum is called the visible light region. The visible light region ranges in wavelengths from about 380 or 400 nm to 700 or 780 nm depending on which source is used. In fact it also depends on the sensitivity of a specific persons eyes.
The most powerful electromagnetic radiation that reaches the retina is blue light. Blue light waves are 400 â 500 nm in wave length and are (obviously) recognized by our eye as the color blue. So when you see the blue ocean and the blue sky, you are getting hammered by blue light.
