The video made me curious about eye protection. For any of the flame colors he created, was there the possibility of a strong UV component that could cause eye damage?

A few years ago I considered showing my kids some pyro demonstrations using magnesium tape and thermite. I know magnesium flame has a strong UV component, and I figured I'd just keep that out of direct line of site. But I couldn't get enough info on the spectrum of thermite flame to feel comfortable going forward with the demo.
