Also, those glasses are one of the main reasons I was given the nickname of Homicide Clyde at work. One foreman I have worked for actually asked me to wear normal glasses and side shields because my safety glasses creep him out. That is actually an older pair with clear side shields. My newer ones have black side shields on them and are a little more disturbing.
With that nickname and my other main one at work of Crime Scene Clean Up, there are a few guys that I have encountered at work that were cautious around me. They had no reason to be though. A couple safety guys have given me a hard time due to the last nickname. It was funny watching a safety guy spend an hour trying to find a trace of an accident and come up empty. Then someone else tipped him off as to what happened and it became a big ordeal over a minor incident. Oh well.
