I discovered yesterday that the steroid drops I put in my eyes fluoresce. I took my 8 year old son to a birthday party at LaserQuest. I always play too. When we go into the first room (which is completely lighted in black light) I looked into one of the mirrors and saw a yellow glow around my eyes. I had just put my eye drops in before going. It was a bit freaky because I was not expecting it.I wiped at it with my fingers and now they glowed too! Way cool.
