As one meta-analysis put it:

It’s estimated that an increase of one hour per day of outdoor time could reduce the occurrence of myopia in children by 45%.

Make sure your kids spend time outside, folks!

Would this mean it’s a bad idea to give kids sunglasses?

Well if that is actually the causing effect, yes. I checked the paper and they do actually mention light brightness as a potential cause, as well as the other things but they have nothing on what actually causes the problem for real.

But I mean, clearly we aren't naturally meant to need sunglasses so in a way I'd say yea, don't give your kids sunglasses.
