Hmm this makes me wonder what did our previous generation of computer people do that had all this evil blue light blasted into their brains?

I feel like this is the new "wellness" science that sounds good in practice, but lacks evidenced based studies.

My guesses:

1. The previous generation did not have laptops.

2. The previous generation did not nearly have as many programmer/hackers/<late-night-computer-user-moniker> as we have today

3. Because of #2, nobody cared if a really small percentage of the population lost sleep due to blue light?

I feel you've forgotten phones. A majority of people have a phone that they can stick in their face in bed.

They created things like Google/SEO, affiliate linking, facebook, twitter, pop-up ads, malware . . .
