My wife is an optometrist, looking at a screen is not unhealthy.
The main problem is that the eyes of children are still in development (growing). When an eye has it's focus too nearby for too long at a time, the eye will grow incorrectly, resulting in near-sighted kids that need glasses.
This means that looking at a book at close range for extended periods of time is equally bad.
Therefore the guidance they give is: after looking for 20 minutes at something close by they should at least focus far away for 20 seconds, also they should be outside for at least 2 hours a day so your eyes receive enough daylight.

- petodo 4y agothe rest of your comment is contradicting your first sentence, since what you suggest is not how people let children use these devices but yeah, I'm also trying to restrict my kids reading time since I'm aware it's unhealthy for eyes as well (as proven by myopia from memorizing in China even way before tablets/smartphones)
- SjorsM 4y agoThat depends how you interpret it. It is fine if you give a child a tablet, with the condition that you also manage the things they do on it, and the time spent. You have to be responsible as a teacher / parent. This applies with all things that children want, but can not yet self-regulate yet, like eating candy or watching tv.
