Hello,

I heard that the refresh rate on the oled screens on the iphone X, XS and 11 Pro has slightly different hertz refresh rates and they are known to cause headaches and eye strain when viewing them for even not long periods of time.

ZolloTech youtuber mentions this quite a bit and says that the 11 pro is best on the eyes but am wondering how to see it myself.
I’m wanting to purchase a new iPhone for my grandma but if this is a real issue I may just get her the 11 or the XR.

I would definitely get an 11 over the Pro’s for your grandmother. Unless she really wants the 3rd lens, it’s the best bang for your buck...

Also, I don’t think you can see PWM, you either perceive it or you don’t. Everyone’s eyes are different.
