I'm not so sure that it's a simple matter of fashion. Wearing glasses is, for lack of a better term, 'normal'. I don't know the statistics but probably a quarter of the population has impaired sight (I'm one of them). Additionally in the majority of cases it presents no handicap at all once corrected - often it results in acuity above the average.
