The 2014 Nobel Prize in Physics was awarded to the inventors of the blue LED. This light source is far more long-lasting and efficient than the existing alternatives.

However, bright blue light sources can pose a risk to the retina of the eye. The use of blue light protective eye shields is necessary when being exposed to blue LEDs.

Dr Ellen Bruzell’s presentation was titled:
The dark side of the Nobel price winning light.
