This is from the book. They filled in missing DNA with frog DNA and the park's dinosaurs were insensitive to movement as a result. This is only hinted at in the movie during the animated Mr DNA sequence.
I read in a neuroscience book that human eyes work that way too, but vibrate slightly the whole time to enable us to see stuff that isn't moving.
Found a source of others are interested: https://www.rochester.edu/newscenter/fixational-eye-movement...
You shame me into making the effort to quote from the book.

> Beyond simple line-detecting neurons, [David] Hubel and [Torsten] Wiesel also discovered neurons that love to track motion. Some of these neurons got all excited for up/down motion, others buzzed for left/right movement, and still others for diagonal action. And it turned out that these motion-detecting neurons outnumbered the simple line-detecting neurons. They outnumbered them by a lot, actually. This hinted at something that no one had ever discovered before — that the brain tracks moving things more easily than still things. Why? Because it's probably more critical for animals to spot moving things (predators, prey, falling trees) than static things, which can wait. In fact, our vision is so biased toward movement that we don't technically see stationary objects at all. To see something stationary, our brains have to scribble our eyes very subtly over its surface. Experiments have proved that if you artificially stabilize an image on the retina with a combination of special contact lenses and microelectronics, the image will vanish.

This is a plot point in the excellent Peter Watt's novel Blindsight.
