The document discusses children's increasing use of digital devices and the potential effects on their vision. It notes that many children spend 3+ hours per day on devices and most have their own smartphone/tablet.

The document recommends parents schedule annual eye exams for children and watch for signs of digital eye strain, encouraging breaks from screens every 20 minutes according to the 20-20-20 rule.
