I've had brain fog ever since my PCS started, and I've always found it hard to differentiate between that and actual vision problems. To start with it felt like my eyes took longer to focus, but as the fog has made a slight improvement that doesn't seem to be the case.

I had my eyes tested not long after PCS started and there was a mild difficiency in vision, however not enough to warrant glasses. Lately I've noticed my vision deteriorate and am going back for another eye test. Perhaps importantly, the deterioration is with the same type of vision, long distance, that showed a slight weakness in my earlier eye test, so may it's just normal.

If I had any PCS related vision problems would it be blatantly obvious like everyhthing else? I see blurred vision as a commonly stated symptom but I'm not sure that applies to me. Things are starting to blur in long distances for me but nothing drastic and it's only recently that it's become noticable.

Would appreciate any thoughts.
