You’re right in that you can’t rub your eyes for at least a month after LASIK. I’m a habitual eye rubber too, so I know the pain of keeping my hands away from my eyes.
If you are worried that you may subconsciously rub your eyes at night, that’s what the protective goggle you will wear for the first 2 weeks or so are there for.
Besides, rubbing your eyes are actually kinda bad for your eyes, so maybe take it as a motivation for quitting! (Sad to say, I’ve relapsed back into my bad habits).
