A lot of times, teams ship their safety glasses in their crate or have them in the stuff they bring in the night before competitions. I don't think it should be a big issue for someone from the team to check out a pair so they can go grab some from their pit. They could have a system where a mentor from the team can go sign off that they checked out one pair of safety glasses for that purpose. If they don't return them in a timely manner, then you can send someone after them to get them back.

Honestly, I don't understand why this is such a big issue. Humans make mistakes and forget things or sometimes accidents happen (I've had a pair or two of safety glasses slip out of the pocket in my Hawaiian before).
