title: Benjamin Martin's visual glasses.
abstract: Although a modern analysis of Martin's theory for visual glasses would probably concur with his detractors, he certainly has provided modern collectors with a style that is much desired. It is interesting to note how many specimens have survived 200+ years. Are they so curious in appearance that people have not discarded them? Were they better-constructed than other contemporary spectacles and, therefore, lasted longer? Or, were they very popular, with the opportunity for many to survive?
