This is an entire category of proteins known as Crystallins. Crystallins of one kind or another seem to be used when pretty much any living species needs to grow a lens. They aren't exclusive to lenses, either; many crystallins are found elsewhere in an organism's metabolic pathways, such as the nervous system.
I found this paper from 1996 titled "Lens Crystallins of Invertebrates" which I'd say is exactly what you're looking for. There wasn't much for arthropods, but it mentions Drosocrystallin for the Drosophila fruit fly's corneal lens, and antigen 3G6 as "present in the ommatidial crystallin cone and central nervous system of numerous arthropods".
To be fair, this wouldn't be nearly as true if we had persisted with our original plan which was to reprocess the spent fuel, more than 90% of which is still usable material. Once we found a couple huge deposits of Uranium, it became much cheaper to simply mine more of it and dispose of the spent fuel, so the recycling plans were scrapped. Sure, we can technically still pull the spent fuel back out again and recycle it, but we spent many years building reactors without building an equal capacity of reprocessing facilities (which are almost as hard to build safely as reactors), so that ship has more or less sailed.
