Not really. The geass broke itself. Rai and lelouch's command of the King geass has limitations aside from the range type of stuff. (although Rai requires no eye contact, and has far superior range)
-The victim must understand the command. You can't just geass them if they don't speak the language or understand the context of what your saying.
-Duration depends on how the command was worded/phrased. Like jump instead of jump till you die.
-Most important is that it has to be possible within their human limitations. they can't geass them to do something impossibly like fly, etc. Also geassing them to live doesn't make them immortal.
In the case of Euphie, her geass broke off because her body and mind were near death, and outside of her limits to follow. Same with Shirly. The geass didn't affect her mentally at all because it was an impossible command to carry out.
Another ex is carve-tan. (the girl in S1 that Lelouch made carve the wall to test the duration). It was confirmed that even during S2, She's still under the effects. She wakes up at the middle of the night (day time japan) unknowingly and tries to get to the wall. It got to the point where her parents had to put her in an institution. Untill either she gets her arms broken/ripped off, Orange de-geasses her, or She gets Alzheimers and her mind forgets about it, she's forever going to have to follow the command.
