Probably because wearing eye glasses signals a handicap whereas this instead could signal being part of an in-group.
Kind of like torn jeans. Before the mid sixties torn clothing would signify economic disadvantage and you’d avoid it if possible but afterwards it signified rebellion and people wanted to signal rebelliousness with torn jeans or at least signal being part of an in-group however large and diluted it be.

It still does. Absolutely insane to me that people are willing to put on the appearance of being poor, and they think it's cool. You will never catch me wearing ripped jeans, but maybe that's because I grew up poor enough that I had to wear ripped jeans when we couldn't afford new ones.
See, the elites can tell the provenance of the rips at a glance.
Whether it is a high fashion rip of the season, made by artisans, versus some counterfeit rip made at home or in an unlicensed sweat shop versus the unimaginable actual wear and tear of old clothes.
