I regularly put Lacrilube on my eyelids, in fact I buy it mostly for that purpose. I don't really understand how it could be a bad idea. It really helps me, as it deeply moisturises my eyelids without irritating my eyes.
I know Vaseline is a similar product, but I can't bring myself to put it under my eyes as I have it in my head that it'll give me spots. But I'll slather Lacrilube on. Plus Lacrilube is sterile. Also, is Lacrilube travels up from under my eye into my eye, then there isn't an issue. I'd be hesitant putting a non-opthalmic ointment near my eyes.
