and many spend 8 hours at work in front a screen :(
I see a simple solution: a 6-hour workday to bump that excessive screen time up to 4 hours.
Seriously, though, I wonder if people who do not work with a PC are less affected.
>however research shows that adult brains are also negatively impacted by excessive screen time, defined as more than two hours a day outside of work hours.
My first thought was it's funny that 8 hours at work is fine but 2 hours at home isn't.
A book would not tick any of those marks
An ereader would account for looking into a light source only if you use background illumination. And even then, it can be set to emit significantly less light than a smartphone screen, especially in the blue frequencies
