My brother claims he has Trivex lenses that are sun sensitive. They are
sun sensitive but I can find no information the Trivex lenses can be
made as such. How is this done. Is it a a composite lense with Trivex
and Photo-Sensitive lense?

TIA,
Dan

Trivex is the type of plastic, Transitions is the photochemical that is
added to the Trivex, just like it can be added to CR-39 or to Polycarbonate
