Optician

Today I had an appointment at the local optician.
She was testing me and I will get new glasses next week. I'm looking forward to it, as I noticed how bad my eyesight in reality is ;-)
This cartoon is hanging in her examination room:
"My eyesight is still pretty bad!"
"Well, I'm not an optician, just a tattoo artist."
I like the strange humour of Joscha Sauer and his cartoon series NICHTLUSTG.de (not funny)
