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!

    Sometimes I wonder if people see numbers like 45% and think “OMG, 45% chance!” instead of “small number * 1.45 = another small number.”

      Considering that a fairly large percentage of children develop myopia (as high as 80-90% in some countries) a 45% reduction would be fairly significant, no? Or am I missing something

        where are you getting these numbers… from what I can see, the global average was 23% in 2000 and 34% today.
