TRIZ says to solve it with ablateable materials- thin foilsheets with a evaporating binding agent - there are uv-resistant plastics https://topas.com/uv-transparency/ even transparent ones, but they are not printable.
It’s for teachers and their students, so presumably they don’t need it anymore after the class experiment is over and durability isn’t a concern? And they could always print it again.

what is the best plastic to print these lenses from? I've found over time all of the clear prints I've don't suffer from UV degradation.
I don't think this project has you printing lenses- it wouldn't really make sense. It's very time consuming to print lenses. If you are going to do this, it makes more sense to print a mold and then cast resin (even then, this only really makes sense if you need a highly custom shape and are making multiple copies). See https://www.instructables.com/Making-Custom-Lenses/ https://formlabs.com/blog/creating-camera-lenses-with-stereo... https://www.instructables.com/Resin-Casting-Lenses/ i would use UV-resistant epoxy casting.
