I am a RE Broker my eyes are 76 years old. The size of the phone may determine if I need glasses to view some text. If it fits my pocket like the 12 does, I will buy the biggest size I can.
I am 71 and I hear you! Thank goodness for large screens, magnifiers, and being able to increase font size. I never thought I’d see the day where my eyes started giving out. Ugh.
