This is going to sound very odd but recently my right squints (enough for me to not really see anything out of it) unintentionally. The strange thing about it is I wont have noticed it, it normally takes someone asking me what I'm doing for me to realise. Last night I was sitting watching tv and my partner kept repeating 'what are you doing?' and it took me a while to even realise what he was talking about. Apparently it was flickering as well.
Does anyone know what this is or if its related to anything in particular? Its only a very recent thing.
