I don't think the "pockets of light" phenomenon is unique to light-polluted areas. In Cherry Springs[1] if there's a full moon and your eyes are adjusted to looking at things bathed in moonlight, you're still not going to be able to see things underneath trees. Natural light isn't somehow more diffuse: if anything it creates more striking shadows because the light is coming primarily from a single source. I'm honestly not sure where you're getting this idea from, or why you're stating it as fact. Are you just unintentionally overstating a hypothesis here? Or do you have some information that I don't? I'm certainly not an expert on how sight works, but nothing from my experience in the wilderness matches what you're saying. [1] https://cherryspringsstatepark.com/ https://cherryspringsstatepark.com/
