Don't know if this will help in any way, but... I worked for a buyer at a department store who had it. Every season, he had to pour over pink order sheets for several days and found it bothered his eyes a lot. He claimed that it wasn't the long hours so much as it was the combination of black ink on pink paper. He tried photocopying the sheets to white, doing his work, copying them back to pink, and found that it helped greatly.

No... I don't think he toked.
