I wouldn't agree with that. People may have made their choice based on incorrect research or incorrect assumptions: there is value in discussing the latest research.
It's like saying discussions about whether cigarettes are good or bad for you are pointless, the important thing is that people are able to buy them if they want.
Well I never made a decision based on a pretense that I was going to save my eyes by switching. I just prefer one particular scheme better and find more pleasant to work with all day, it doesn't need to be anymore complicated than that for me.
Your comparison to the cigarette discussion is an interesting point. The article didn't present anything particularly strong in regards to studies around this though so I'm unsure what there is to discuss, aside from speculation on whats good and bad for our eyes. If we're speculating I'd wager regular breaks and getting away from your screen as much as possible is far more impactful that which color scheme you choose.
No sorry, that has nothing to-do with research, but taste.
In fact, research like that i call bullshit, its like 'research' food, 'scientists' found out that that people prefer yellow carrots because red is a warning color.
