> anyone know of a good article on why blue blocker sunglasses have an effect on 'mood', if any?
I don't know of a good article about it, but it's easily explained. Sunlight is harsh. Filtered sunlight is less harsh. Blue is harsher than the other wavelengths.
Anybody who spends a lot of time outdoors, does one of two things. They wear sunglasses, or they squint and curse their fate.
