The "Don't look" comment was a tiny humorous reference to the well-known science fiction story [The Day of the Triffids], in which carnivorous plants terrorise a population... that was mostly blinded by, well:
"The narrative begins with Bill Masen in hospital, his eyes bandaged after having been splashed with droplets of triffid venom in a lab accident. During his convalescence he is told of the unexpected and beautiful green meteor shower that the entire world is watching. He awakes the next morning to a silent hospital and learns that the light from the unusual display has rendered any who watched it completely blind." Perhaps not straight away, or you'd stop. "Later on in the book Masen again theorises that both the 'meteor shower' and subsequent plague may have been an orbiting government weapons' system that was triggered accidentally." But, remember, he's a triffid farmer - or was - anyway, what does he know?
