Chromatic aberration happens because the refractive index of glass is different for different colours. This causes a light ray that contains several different frequencies of light to end up in several different places on the sensor. The result is colour fringing and blurry pictures.
The cause and cure for chromatic aberration has been know for a very long time, some of the earliest computers made by Konrad Zuse were used to calculate the properties of compound lenses. Unfortunately good optics is expensive so we still have the problem to some degree.
