Do we have any eye doctor types on this board? Opticians or ophthalmologists? For the last couple of weeks, I've had this pain in the back of my head and it really flares up when I use my iPad. Not sure if it's my eyes need checking (which they do, been years since I've had a check up and now I've hit the magic 40, I suppose this should be a regular thing), or if it's something else. Like ebola or whatever the latest thing is that will kill us all.
