I have a very hard time with most (not all) bright lights, moving lights and certain very particular levels of luminosity.
The obvious neon lighting and computer screens are my sworn enemies, but so are traffic lights when it's dark, for example, or a certain level a little before the sun starts going down. So I wear tinted glasses most of the time, not as dark as regular sunglasses, just a slight bit lighter (and the type that's darker up top & lighter on the bottom). The glasses are a problem at work because apparently they distract my coworkers, and they can't do any of their work because they're so busy gossiping about my prescription tinted glasses. If I'm home, I'll either stay in the dark with lights off (so soothing) or, interestingly, turn on all the lights, which are bright and warm, a little like sunlight on a good day. For some reason, that doesn't cause my eye to burn or hurt. Neither does sunlight; I mean, I will close my eyes if it's too bright, and I have a lower threshold than most, but the reaction seems more normal than my aversion for other lights.
Regarding the pain: I get a burning sensation, I do have drops for excessively dry eyes (drops with boric acid and hyaluronic acid + some kind of ointment that completely blurs my vision for 5 minutes, but 6 times a day) that have alleviated the feeling of sandpaper on my eyeballs, but I also often get the weird sensation that my eyeballs are simultaneously violently pushed into their sockets (as if someone were pressing them in with their thumbs) and about to fall out. Eye exams showed nothing, so I don't know what's causing it. I thought it had to do with how tense I was.
I've never considered hunger, though. I am getting this feeling (the pain) right now, and I am also feeling hungry, but it's the first time I'm paying attention to a possible correlation.
