I've found that reducing the screen brightness (I went from ~75% to ~55%) reduces the snow-blindness somewhat - should improve battery life too 
I've also spotted that the App Store doesn't clear updates. In iOS 6 if you closed App Store and re-opened it the last lot if downloads had gone but they are still showing 10 hours later (and I've re-booted my phone too). Presumably they will go when new downloads appear?
