I spent my entire childhood reading, my teen years hacking, and my adulthood as a software engineer and gamer. I've spent my life doing all the things mom warned you about. I'm in my 50s and still have 20/20 vision.
Funny you say that, as I just got back from an eye appointment and in my 50s also still have 20/20 vision (after more than 40 years of programming/staring at the screens).
