I want iPhones to have screens that adjust for bad eyesight. My beloved iPhone became useless in the last years until I can get out my reading glasses. All those awesome smartphone features suddenly worth shit.
it will happen to YOU as well! (dramatic music)
I remember a university project from about 10 years ago, that managed to do exactly that, optical problems notwithstanding. I always hoped it would find its way into the marketplace. But it hasn‘t happened yet. It seems they needed to add an extra layer on top that diminished the screen quality quite a bit. If I could only find that link.
