Went to the optician the other day, after losing yet another pair of glasses in a messing-about-with-the-kids incident. 
"Your eyesight is maturing" said the optician?" 
"What, you mean I appreciate art and ballet a bit more now and fancy Fay Weldon?" 
"Er, no, you need reading glasses."
"Hmm. So I'm not short sighted any more?"
"You're still short sighted. You'll still need distance lenses as well".

In other words, there is only a depth of field of about three inches in which my vision is clear. 

I am shagged.
