I'll have you know this is a Star Trek: Deep Space Nine household, and we are on our 12th rewatch of the Dominion War, tyvm.
If Netflix ever adds Spin City to their catalogue I will be in trouble.

And will use that infinite potential to binge watch Friends for the 11th time.

This article is about the effects of eye strain, not the overall mental health of looking at content on a screen. With that in mind, what is it about a screen (emitted light) that is worse than outdoors reflect light? One item I can think of, is that looking at something with reflected natural light, the iris contracts based on the total amount of light hitting it. Whereas a screen may be brighter than the ambient li…
That seems quite high to me.
Assuming you sleep 8 hours, that only leaves 16 other hours for potential screen time of which 13 we are apparently looking at a screen. Lets assume another 30 minutes a day for getting washed & dressed, bio-breaks, brushing teeth, preparing food + drink etc (30 mins seems low, but I'm being generous), so 15.5 hours left.
So of all of our waking hours, we spend 13/15.5 = 84% of every minute we are awake looking at a screen? 50 seconds of every 60 seconds staring at a screen?
Seems high to me.
Aaaand now I feel the sudden urge to get away from this screen and go walk through some trees. I'll see ya all later.

Do books do the same damage to your eyes as screens?
Is that really supported by empirical trials? A short search online seems to point to that being somewhat disputed. I'm all for contradictory evidence though if you have some I missed. Yeah sure a screen is emitting light which maybe makes it worse for the eyes to look at in some ways and situations than a paper page, but "looking at light" is almost an oxymoron - isn't that what eyes do?
A white reflective surface (whiteboard) in direct sunlight is 1.6cd/cm^2. Consumer monitors are ~300cd/cm^2
(I'm not sure how much bearing this actually has on eye health, this is just to illustrate how looking at a monitor and at a piece of paper is significantly different)
"Researchers say kids and teens need to get sunlight during the critical years of their development while their eyeballs are still growing.
"The mechanics of how sunlight protects their eyes are not clearly understood. One theory suggests that sunlight triggers the release of dopamine in the retina; another speculates that blue light from the sun protects from the condition.
"The solution is simple. Have kids "spend more time outside, have less demands (from) the schools and relax a bit," said Seang Mei Saw, professor of epidemiology at the National University of Singapore."

Probably? It's not like screens shoot death rays. It seems very likely that looking closely at patterns within a rectangle has the same effects whether it's made of paper or electronics.
