I always heard that e-reader has a technology to not affect/tired the eyes in the long run. Even if a tablet is low on brightness and the blue light filter is on, is it still inferior in this aspect?

Would it be possible for us to live without plastic again? I mean if everyone stopped using plastic, things would become more expensive and would have to be replaced by other materials, in addition to changing customs. But is there something that, without plastic, would not exist in any other form?
