Probably not inflammation, at least not directly. Just part of ME/CFS for some people. I tend to get blurry eyes while driving, but I think that's just the air blowing and drying out the liquid film.
I'll take this opportunity to hijack the title, one thing I've noticed is that t-cell type inflammation makes my pores produce much more (and thicker?) sebum. On a day with minimal inflammation, scraping my fingernail across my nose might collect a small amount of sebum. The last few days, with a sprained arm causing inflammation, my fingernail collects much larger amounts of thick, white sebum. I've noticed this with other t-cell type inflammation. A quick googling supports the connection between chronic inflammation and acne, though it doesn't clearly state that inflammation increases visible sebum secretion.
I'm not sure how common this response is in people. However, if it is, it's a simple way to tell if you are suffering from inflammation. For those of you who do suffer from chronic inflammation or frequent inflammatory events, pay attention to your sebum production (skin shininess, or scraping with a fingernail) and see if it correlates. Posting your responses would help others to find out if this is a useful test.
