I apologise in advance if I sound harsh, but I have found your posts a really uncomfortable read - I wasn't going to reply at all, but then I can't stop thinking about your daughter, and I wondered if there is a tiny possibility you might actually listen to what i am sayinrg.
Uou speak about her really very disrespectfully and unkindly, for a parent talking about their own child. You seem determined to put the worst possible construction on all her actions, almost mocking her stupidity.....
I wonder if she picks up on the contempt you seem to have for her? (And to be fair, for others too - you have reacted really quite rudely to some posters' suggestions, because you are a scientist and only like theories you feel have been sufficiently researched, ignoring the fact that individual behaviour doesn't work quite like that). And does things deliberately to spite you? I have to admit I'd be sorely tempted in her position.
Also if you say things like "screen time is a privilege, not a right'." That very phrase would make me want to never do anything you told me ever again ..... It's a power-trio. Nobody crows like this to their children! And she's 12 for God's sake, not three.
And if she doesn't like wearing glasses, could you not get her contacts? Lots of kids don't like wearing them, it hardly makes her Damien from the Omen.....
This is your child! What do you love about her? What is amazing about her? What makes you feel privileged to have her?
(Don't tell me, tell her. The more loved she feels, the more likely she is to do what you ask her. )
