Mine came back about a week ago after four years, having had two episides and possibly a very minor third some years back, just didnt realise it at the time.
Fortunately, it's relatively mild and seemingly only of the ocular variety, though i have felt tired and achey (esp shoulders) in recent weeks - I don't know if this is connected.
What I have found is that the double vision has been very testing, I feel mentally drained as my brain tries to process whats coming out of the eyes..
I saw the opthalmics on Friday at the local eye hospital, she fitted two pairs of my glasses with prisms (One for long distance, and a weaker one for watching TV 2.5m away.) But I'm finding quite a bit of variability and whereas earlier last week I was fine using a PC screen less than a metre away, it's now a struggle unaided and I nhad to take the prisms off my TV glasses and use for my computer ones.
So I guess I'm asking the same question as Jodi above....
