   Obligatory mention that CR39 was first chosen and very profitably   
   exploited for eyeglass lenses by Robert K. Graham, who went on to use   
   some of his wealth to found the (in)famous Nobel sperm bank.   
      
   But no one is answering my core question:  Does it really cost anywhere   
   near $500 to manufacture a pair of decent quality progressive eyeglass   
   lenses? (and several hundred dollars to manufacture a reasonable quality   
   eyeglass frame?)   
      
   Or is that one specific area where a _lot_ of excess cost and undeserved   
   profits could be squeezed out of our health care system?  (As I'm coming   
   to believe is the case.)
