Eli5:What are the physical and psychological reasons for “screen time” being bad for toddlers/children?

Question

I’m curious if there have been real studies around this. Like, how does watching 30 minutes of simple cartoons a day (bebefinn etc) affect a toddler’s brain? What are the consequences?

Answer 1

I work in eyecare and the studies show that more outdoor time = delay in becoming nearsighted. More outdoor time would mean less time in front of a screen. That’s a good reason on its own aside from other added benefits such as exercise, improved mental health, vitamin d.
