In the Jurassic Park book, the dinosaur's eyesight was based on
movement because they had amphibian DNA that gave them an amphibian
eyesight, which is based on movement. In the movie, this concept screwed
up and apparently interpreted by the screenwriters to mean that T.rex had
vision based on movement, amphibian DNA or no (toward the beginning of the
movie, Grant mentions it when he is psyching out the obnoxious kid).
Movement probably ASSISTED vision. It is easier to notice a moving
object than a stationary one. I'll bet if a T.rex was to walk by a jeep
with people inside, it wouldn't notice the humans if they held still just
becasuse they were so small. Even if a T.rex did see them, it probably
would't have a clue what to make of them anyway.
