If
these are the glasses you are referring to, then I would be wary of if they are technically Amber tint or not. I think they are going to be considered shaded based on what happened to us last year.
These were
our glasses last year. We knew it might be risky but we spoke with the vendor and they told us that they were indoor/outdoor lenses, and are NOT a tint, so we thought we were ok. We do a lot of outdoor summer demos and were worried about the glare on the field last year, so we thought they would be a good choice for our team. We won the safety award in Philly wearing them, but then were told they were illegal by half the UL staff in Atlanta.
So if you glasses are NOT an amber tint, or one of the tints listed, I would bring another pair at least to Atlanta. It might not be as obvious if you don't have a whole team wearing them, but we were definitely told ours weren't legal, so we just got the clear lens version of those this year.
