Are you seriously claiming that plastic lenses are higher quality and longer lasting than glass lenses? Plastic lenses scratch very easily; glass lenses don't. Also, I don't need to write a white paper or do a study to maintain that spring hinges are cheap compared to the barrel hinges. I've seen so many of the spring hinges break on glasses people had bought less than a year ago. They are demonstrably low quality.
