It may depend on your role. When I attended my first event as a volunteer, I was involved in field assembly and field reset/ asst. to the field supervisor. As a result I was lucky to get a nice pair of the loaner glasses before others. However, they were still marked with a sharpie and not the most comfortable.

Not all jobs require safety glasses. If you do need glasses, I'd recommend that you bring your own. They're inexpensive. It's best to know that you'll be comfortable in whatever you're wearing for those three days and that you won't be responsible for returning your glasses to the pit admin or from whoever you've borrowed them at the end of the day.
