Thank you both. Mustafa, I am not really acclimated towards the scientific aspects.
I heard, overnight (on NPR radio), the BBC major report on graphene and was really amazed with how a one atom thick coating could be so strong and, largely, transparent. My first thoughts came to lens coatings after it was announced that major Korean manufacturers had gained patents for coating mobile phone screens. There is going to be lots of new applications to come, possible lens coatings only one of many. - David Lyga
