Limitations of Light Sensors
Andrew discusses the potential limitations of a study that didn't have a sensor capable of picking up the full spectrum of light, including UV light. He also explains the technology constraints of the time and suggests the idea of eyeglasses that measure photon intake throughout the day.In this clip

From a standpoint of ruthless neurobiological efficiency for setting the circadian clock, which is the lesser of two evils regarding eyewear during morning light exposure: blue-light blocking glasses or high-quality sunglasses? Does wearing any kind of filtering eyewear during the morning viewing protocol completely negate the benefits by filtering out the specific blue/yellow wavelengths needed to activate the melanopsin retinal ganglion cells, or is the sheer intensity (lux) of outdoor light sufficient to overcome the filter to some degree? Is it a binary 'works/doesn't work' situation, or is there a gradient of effectiveness?
