To some extent it has to be, in much the same way that extended computer use can be bad for our eyes right now. I don't think that looking at these types of things is unnatural, but rather it's how intently we focus on them for long periods of time. It's very easy to forget how long you've been on a computer or been watching television.
I honestly believe that yes because I know staring at a computer screen for 8 hours a day at work has made my eye sight worse. I used to just wear my glasses for some things but now I find I have to wear them much more often. And if the computer can have that effect, I can only imagine that 3D TV will be even worse.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
