Purple Eyeliner and Red Eyes

On occasion I wake in the night to red and crusty eyes, feeling like acid was poured into them. It only took me about a year to realize it was my old purple eyeliner that did it. So I threw it out, quite pleased I had finally solved the problem.

Yesterday I bought a new one - fresh and unpolluted - because after all purple eyeliner is so cool.

Guess what I woke up to today?

What is in purple eyeliner that does this to me??

You mean I'll NEVER be able to wear purple eyeliner ever again in my whole life???
