"13 Pro almost made me buy correction glasses. Older version of 13 Pro. Sold the phone and the eyesight recovered in 2 weeks."
I bet you when he sold the phone he didn't tell the buyer why he was selling it. Maybe the buyer is being harmed also?
Update: this person is comfortably using the Moto G 2025. Therefore, this thread connects to these two:

Also can include this iPhone anecdote:
"Got my 14 Pro Max device delivered today. Unfortunately for me, the 14 Pro Max didn’t work out as the case was with 12 & 13 Pro max. After around 30-45 mins of usage, terrible eye strain, nausea & blurred vision. PWM all the way up to 100% brightness level it seems… So Regardless of PWM frequency bump for the 14 Pro’s , the issue still persists imo. Maybe different for others."
So that's one of the big problems with Apple. Once you're on that ecosystem you are at the mercy of Apple's products. At least with Android we have way more freedom, choice, flexibility.
Also can include this Samsung S23 Ultra anecdote:
"DO NOT BUY the S23 Ultra if you have PWM sensitivity. Holy hell what were they thinking. Looking at the screen for a a few minutes feels like you are getting your eyes gouged out. I was worried I was going to have permanent damage it was so bad. Returned it after 2 days."
Fortunately no one is required to use the S23 Ultra to enjoy a full Android experience.
Remember if using an OLED smartphone to keep the brightness at 100%, always. Then use Reduce White Point or Extra Dim to achieve your desired brightness level. If still too bright, wear tinted computer glasses. With Extra Dim properly adjusted and tinted computer glasses, no display will be too bright at 100%. These tips will allow many more sensitive users to enjoy certain OLED smartphones. Last but not least: ensure your room lighting is adequately bright. Using any display in a dark environment with inadequate lighting is bound to cause issues. In fact, bringing your smartphone out into daylight will all by itself dramatically increase the comfort of the display. Notice I said daylight, not sunlight. I'm referring to abundant natural light without any sunlight reaching the screen.
One more anecdote for this thread:
"I can only use this phone [Sony Xperia 1 IV] at 100% brightness and using an app called PWM free, anything less i get eyestrain. Thinking about just going back to my Xperia XZ1 and carrying the 1 IV in my pocket only for photos. Wish i there was a really good flagship with IPS screen, cant stand OLED and AMOLED."
Of note, they claim they can't stand OLED even though they admit to achieving success at 100% brightness with the help of a dimming application. Remember as I said to ensure abundant ambient lighting AND to add some tinted computer glasses if the screen is too bright at 100% brightness using Extra Dim to lower it. Having plenty of light around your screen should make it so you can use comfortably 100% brightness and Extra Dim without any glasses, but the glasses are not going to hurt, and do help many.
