So as a result, our nature has...we have evolved to have this light sensor, this specialized type of light sensors. These are called melanopsin or blue light sensing light sensors that are present in our retina. These are not necessarily for seeing the outside world, but this light sensor senses blue light. And why blue light? Because the sunlight is the best source of blue light. When we say blue, it's around 450 nanometer to 500 nanometer, that range.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
