González-Acuña and Héctor A. Chaparro-Romo present an analytical solution for a problem that was only solveable by numeric approximation for the last 2000 years: How to shape one side of an (aspheric) lens such that it completely compensates the (non-chromatic-)abberation of the other side.

I'm not quite sure whether the use of the new analytical solution (in comparison to a numeric approximation) will make a significant difference for the practical process of designing lenses, but the article "Goodbye Aberration: Physicist Solves 2,000-Year-Old Optical Problem" at petapixel.com on this is definitely an interesting read.
