Lol Sheryl!  Um, my pee wasn't green!  I didn't have to have any drops or anything for the optometrist appointment.  For the picture, they had me look into the lense of this really huge machine, then there was a bright green flashing light that took the picture.  Then they sent the picture to my doctors computer. I went into his office and he discussed it with me as he was showing me the image on the screen.  Really cool to see my retina on a 22" wide screen.  
 Yeah, the $572 is just for lense/prescription upgrade for my current frames.  I like my frames, so I didn't bother with any new ones.  The lenses are supposed to be the latest thing...kind of like a tri-focal - he gave it some special name - I can't remember what he called it. 
  
 I will try to get here more often
 Take care
 Chris
