This category lists all comics which mentions Google Glass, which has become a recurrent topic in xkcd.
It seems generally that Randall is no fan of Google Glass, which was shown directly already in 1251: Anti-Glass and later again in 1304: Glass Trolling. But also in the other comics (so far) Google Glass is not shown in a good light. In the first reference to them, 1215: Insight, it turns out Cueball/Randall fears this new technology (could have been any new technology but Randall chose the glasses). In 1288: Substitutions they are substituted with the silly Virtual Boy and in 1716: Time Travel Thesis they are jus "these broken glasses" Megan used in a 2010s theme party.
