@nonayadambidnes: I know from experience that old, fat drug addicts can launch some genuinely eye-watering SBDs. Maybe that's what they got for sitting behind one. That said, depending on the location of the lights rigging above the stage, it is possible that they got a light sprinkling of metal dust and plain dust coming down from the lights. (That happens sometimes at events and during theatre productions.)

I went to Tucson twice for work and got sick both times. The dust and wind there played havoc with my eyes.
@nonayadambidnes @thedisasterautist
I can totally believe that. Since cataract surgery my eyes are extra sensitive to even small amounts of dust. (Plus my contacts used to shield my eyes some.)
@Agatha @nonayadambidnes @thedisasterautist
If I had to guess, I would say an ultraviolet spotlight aimed over Trump's head at that side of the stage. I don't know whether that's something that is normally used in a theater, but there have been instances where the wrong type of blacklight was used at a public event. It could be very localized in the right light fixture.
@AlphaCentauri @Agatha @thedisasterautist Oh that is really interesting.

The one willing to go on record said she was fine until she went outside.
