    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?

  2. 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
