Without spending 8-12+ hours a day staring at a screen, I probably wouldn't have needed glasses.

Far as we know currently, looking/staring at screens does not cause permanent damage to your vision.
Screen time is no worse than book time or sewing time or Wolfenstein time.
Concentrating reduces your blink rate. Reduced blinking dries out your eyes. That's the main detrimental effects.

There's evidence piling up that there is an inverse correlation between outdoor time in childhood and nearsightedness. It's believed that the brightness of sunlight helps stimulate eye growth in a spherical shape, whereas children who don't get a lot of sunlight are more likely to have eyes grow in a non-spherical shape with greater distance between the lens and the retina.
You can search the scientific literature for myopia and childhood sun exposure for a large number of studies on the topic.
Does screen time correlate with myopia? Maybe, but through the confounding variable that both stats tend to be inversely correlated with sunlight exposure.
