Graphene, (isolated in 2004 by Andre Geim and Konstantin Novoselov at the University of Manchester; they won the Nobel Prize in Physics in 2010), essentially a one atom layer of graphite which is unbelievably strong, is slowly emerging into the marketplace as a coating which provides extreme durability for cell phone monitors.

I am wondering if anyone has heard of pending optical applications as a coating for lens elements. Certainly, the ability to almost guarantee scratch-proof lenses has to be of major importance. - David Lyga
