I’m not over 50 yet, though I’m rapidly closing in on it, my eyesight though is probably a good 20 years older than me, terrible eyesight.
I’ve also let my dad, who’s in his 60’s have a play around with my old iPhone X and my Pro Max because despite him barely using the features of an iPhone, he likes to have the latest one, fair ‘nuff.
I don’t have a problem with either, but more importantly to you I suppose, my dad has no issues with them. In fact he says they’re the best screens he’s ever seen and can more clearly see what’s on them than he can with his iPhone 7.
