the book contains info about the history of eyewear. From the ancient Egypt to these days.
To be honest, I mostly interest the glasses from the 60's to today, but still its nice to see what kind of glasses people wore like in the start of the 19th century. This book also reveals the fact how much the eyewear industry went downhill in the 90's :/ Many brands changed their factorys to China or somewhere else cheap, and good brands that still made with quality died slowly. People just didn't care about quality no more. -__-
