@sunnyflower I have double vision, probably a symptom of autonomic neuropathy. I had a prism ground into the right lens of my regular glasses, and it was better for a month or so, but has returned with some new variations. Most of the time I just deal with it, but as it progresses it could become an issue. I hope it doesn't become bad enough that I would lose my driver's license. @avmcbellar has written about treatment options.

My eyes get tired after reading very much, both print and digital. After going through posts here for a while, I need to go lie down and rest them.
