Chromatic Aberrations are the optical errors that occur at the bound of light and dark in images because of errors in the lens. But you can make them in post using this template. The plugin will cause random motion and distortion across the colour channels separating them out and moving them around.
You can customize the amount of the distortion, how blended the effect is with the original image, and how often the distortion occurs.
