Parallax is a noun defined as, “The effect whereby the position or direction of an object appears to differ when viewed from different positions.”
Things look a little different for your right eye than for your left eye. You don’t usually notice, but parallax is why you have depth perception in your vision. Two non-identical perspectives give a more accurate picture of the real world than just one perspective.
People who wear Cochlear Implants have the important (and difficult!) position of living in a space of cultural parallax. When you’re Hearing the world seems different than when you’re Deaf. Hearing and Deaf live in the same world, and both are needed for everyone to better understand it.
The application of the term “parallax” to the field of cultural and disability studies comes from Slavoj Žižek in his book, The Parallax View.
