Google Glass users take note: If you're a fan of comics, movies, or excusive looks at comic-themed movies (or any movies in general, really), then you might have a bit of an issue at this weekend's Comic-Con in San Diego.

According to convention rules, talk of which just started hitting the Web today, Google Glass is not permitted during the times that eager geeks might want to secretly whisper an "OK Glass, record a video" command.

"Remember recording of footage on the screens during panels is prohibited (see below: No Video or Audio Recording of Movie and TV Panels). This includes Google Glasses. You cannot wear Google Glasses during footage viewing in any program room. If your Google Glasses are prescription, please bring a different pair of glasses to use during these times," reads Comic-Con's official convention policies.

The news shouldn't be too surprising. Theaters in the U.S. and the U.K. have banned or limited the use of the high-tech specs in the name of piracy.

"As a courtesy to your fellow audience members, and to prevent film theft, we ask that customers do not enter any cinema auditorium using any 'wearable technology' capable of recording images," the U.K.'s Cinema Exhibitors' Association (CEA) said last month. "Any customer found wearing such technology will be asked to remove it and may be asked to leave the cinema."

That said, even some of the CEA's individual operators are taking a bit more lenient stance against Google Glass: Vue Cinemas, for example, will let patrons remove the devices as soon as the theater's lights begin to dim prior to a film being shown. That's the same policy held by the Alamo Drafthouse Cinemas chain in America  lights go off, Glass goes off.

Of course, Google Glass can only record about 45 minutes or so of continuous footage before its battery gives out, which makes it less than ideal for feature-length films (unless one really wants to go multiple times and combine the footage). At Comic-Con, however, the most highly anticipated clips are usually trailers or movie clips that are several minutes in length, which could be captured by Glass.

Google Glass isn't banned from Comic-Con as a whole. Wearers will be free to "OK Glass" as much as they want toward people dressed up as Deadpool and all that. Just don't try to sneak them onto your face when J.J. Abrams debuts the new Star Wars trailer or something  not unless you can send us what you've shot!
