100% agree. As someone who is sadly now closer to 50 than 40, I have endured a marked decrease in my ability to focus on things close to my eyes, such as ... my phone. This is especially painful for me because for most of my life I have had better than average vision. I still have great vision at a distance, but at arm's length I struggle. And reading glasses make me ill. It kinda sucks.

So I completely appreciate accessibility options. I've tweaked my iPhone settings to improve contrast wherever possible. What annoys me a lot is how many app designers think some form of gray-on-gray text is perfectly readable. No, no it's not. Black on white, white on black. Something with more contrast, please.
