After learning about the dangers pwm causes i realise majority of phone users have no Idea about it, i recently talked to some family members about it and they were shocked, one even remembered how iphone x caused him so much eye issues but he had no idea why and sold it.
I think what it comes down to is that there is some theory PWM should be benign, but in reality the brain simply is too sophisticated and profound for such shoddy man-made technology. Could be OLED is deliberately intended to mess with our brains. Who knows.
From the Bible billions of people allegedly take seriously. Ephesians 6:12, KJV:
For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
