Does anyone know why eye drops would be on the no-no list?

The security team at a concert venue in Portland, Maine confiscated my eye drops last night when I went to see Elle King. It was a great show at an amazing venue. My only issue is trying to understand what possible reason my dry eye medication would be taken from me. The product did not have any iodine or other chemicals in it. I explained this to the woman who examined my purse and took the drops from me. When I asked why, she and another employee could not give me a logical reason except to say "they have had problems with it before, and other venues also did not allow eye drops."

So, I am stumped. Do any of our listeners know why?
