I tend to go to the opticians on the way to work, this means:
1) I'm there about 60 mins after falling out of bed
2) I'm at morning hydration levels (i.e. not)
My optician has reassured me in the past that the stuff I just read going out of focus is normal because of the above.
What I always find worrying is THEY ask ME questions about my bilateral coloboma as if they've never seen it before (they haven't, ever, well except possibly in textbooks)
