Question: One of the boys, called Piggy, wears glasses. Piggy's glasses become an important, prized object, because the boys can use the lenses to refract the sun's rays, and thus start fires. It is fairly well established, that, on a hot day, in bright sunshine, one can focus the sun's rays through a magnifying glass to set light to combustible material. (I've done it myself, although it took me rather longer than the book or film suggested, and it only made a very small flame.) But could you use spectacles, that people wear to correct defective vision, to start a fire in this way? Surely, if this was possible, wouldn't it mean that when people who wear glasses went out in hot sunny weather, then they would burn their eyes?Rob Halliday
Trivia: The attempt to make the locations look wild and uninhabited were obviously not altogether successful. Near the beginning of the movie, some boys are sitting in a sandy clearing in public-school blazers. On the right of the screen you can clearly see a tent peg with ANTONY M written on it. Also, as one of Jack's choirboy-hunters thrashes through the undergrowth, look closely and you can see that he accidentally impales an old beer can.
