It is true that nerd glasses are still in fashion. They are currently use by many including celebrities as a fashion statement. They are growing in popularity because of the way they change the look of the face instantly.
Not really sure if they are still in because I have not seen nerd glasses anywhere lately. Additionally, nerd glasses are really difficult to pull off, you may be ridiculed if not complimented. Anyways, even if nerd glasses were in it would be hard to rock them unless your drop dead gorgeous or a stud. Just my opinion
