I&#x27;ve read this too, I guess I&#x27;m still a little sceptical based on my own sample of one. When I was a child I spent loads of time outside, but also loads of time on the computer. I guess the computer won.
I also don&#x27;t understand how they separated out &quot;doing close work&quot; from &quot;being indoors&quot;. You&#x27;d need a control group of kids who spent a lot of time indoors WITHOUT doing much close work. So what would they be doing instead? Even if you&#x27;re not reading, surely all indoor activities involve somewhat close work. Watching TV or playing console games might not have met the researcher&#x27;s definition of close work, but they still involve focusing ones eyes at a point closer than infinity.
