I had a really crappy night's sleep last night and feel foul this morning. My eyes don't seem to be working properly today - i'm having trouble focusing on my computer screen on and off. I thought I had a bit of yuck in my eyes, but it the blurriness comes and goes when I blink or rub them. Mostly it's like I've suddenly developed severe short sightedness!

I had my blood pressure taken the other day and it was fine - 130/85.

Would you be concerned?
