I came across this site today. My iPhone 11 is failing, so I was browsing the web.
I went to Verizon today, took a slow mo of each iPhone 14 (10 seconds each). So roughly 30-60 seconds looking at the 3 of them. I could barely walk out of the store and drive home. My eyes felt full of pressure, my face got hot, I was nauseous, headache.
