When I first fell ill with the original virus, my eyesight seemed to coincidentally get worse. I had to go to the optician who prescribed reading glasses that were horrendous to use. The next optician I visited a couple of years later thought they were way too strong for me. But I did have problems with blurred eyesight early on, and it was variable. The second optician a couple of years later also prescribed a pair of glasses I couldn't use. And one of the opticians I saw was very dismissive of the variable eyesight issues in ME, just saying that everyone has variable eyesight. I decided to forget about reading glasses, and fortunately my eyesight improved. However, in the longer term, eyesight always deteriorates with age, so at some point I'll need to do something about it. I know some of you have different strengths of reading glasses and you just choose the strength you need at any one time. If anyone has anything to contribute on the blurred and/or variable eyesight, feel free to post here. It does seem to be common enough for research to have been done - I think we're supposed to have problems with tracking lines in books, amongst other things. Obviously seeing an optician every few years is advisable because it can pick up on other medical issues too.
