one thing I have noticed about the sun, is that when I was younger and eating a SAD diet, I could look directly at the sun and it wouldn't hurt my eyes. Now though, I don't know if it is because I have been staying indoors for too long, as I have gotten pretty pale and am not as tan nor do I tan as easily as I used to, or if it is because I have been eating raw, but now the sun hurts my eyes a lot more than it used to. I have noticed also that my eyes have gotten lighter since eating raw, and I don't know if that has anything to do with it. I've heard tell that lighter eyes have a harder time looking at the sun for some reason.. though my eyes are still brown and not THAT light. But I do notice that once the sun reaches below a certain level, and is closer to the horizon, I can stare directly at it for as long as I want and it doesn't hurt my eyes at all. I don't know if that might be because it dips below the layer of smog that we always have, and filters the light enough to make it less painful to my eyes, though.
But I have been trying to sungaze a little whenever I can as a way to naturally improve my eyesight, because I have some pretty bad eyesight, and I don't want to have to wear glasses or contacts. I was also hoping that sungazng might help me in fasting for Ramadan, but I don't feel like I have much less of an appetite than I would if I didn't sungaze. I don't sungaze very properly though, the only time I have access to be able to stand on pure dirt with my bare feet is when the sun is quite high in the sky and difficult to stare at, and the only time I usually get to stare at the sun when it is low enough to be painless is when I'm driving in my car and there's no dirt and I'm wearing shoes anyways. Although then at least I usually roll down my window and take off my glasses so that there is no glass between me and the sunlight.
I don't really believe that it's possible to survive on sunlight either though, it might perhaps help with reducing appetite, but I don't see how it would be possible to eliminate food entirely just from staring at the sun. Like I heard one person ask, why then do the starving kids in Africa, with access to so much sunlight, still starve to death?
I usually keep my shutters closed, but I did leave them open once and the sunlight ended up directly on my face and it did wake me up. But that might only be because when I felt the sun on my face I realized I had left my window open and that I needed to get up and close it so as to not let in all the heat, because it gets way too hot for me if I leave my windows open during the day,
