I just had a client come in for an eyelash tint. He was so cute, he just wanted to match his blonde eyelashes to his red hair. But he was so nervous and as soon as he got into my room he goes, "can we just do one eye at a time?" I said "Sure we can but it's going to double the amount of time it takes and it won't make any difference to your comfort level."
So he says, "Yes but if it gets in my eye and blinds me, I will only be blind in one eye."
When I was lash tinting in beauty school, the student practicing on me got some in my eye. When she asked the teacher what to do, the teacher said "Go to the er" . Haha!
