Warning: mktime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Djeca koja su postala kratkovidna provodila su u prosjeku 8,3 sata tjedno u aktivnostima na otvorenom, za razliku od djece kod koje nisu nastupili problemi s vidom, a koja su vani u prosjeku provodila 12,6 sati. S druge strane, kratkovidni su više vremena provodili ispred televizora: 12,5 sati tjedno, a 8,4 sata provodila su ispred ekrana djeca koji nisu imala problema s vidom. Iako je kratkovidnost nastaje i zbog naslijeđa i zbog utjecaja okoline, istraživanje upućuje na to da djecu u razvoju treba poticati na aktivnosti na otvorenom.
