If you have a dropper. Boil it, and them put some cooled boiled water in the dropper and srop it into her eye the way you would regular eye drops. Water wont hurt (no chemicals) and it should wash it right out. GL
I'll probably get bashed for this, but when DS has something in his eye no matter if it looks like it's bothering him or not, I wash my hands really good then as gently as possible try to wipe it out or grab it somehow with my finger.
