According to a 2013 survey conducted by the American Optometric Association (AOA), 85% of parents indicate their children use an electronic device up to four hours per day. The survey also indicated 41% of children have their own smartphone or tablet, and 32% use both e-books and textbooks at school. Also, 66% of children use a computer or tablet to do homework or study.
Extended use of technology can lead to a temporary vision condition called computer vision syndrome (CVS). Symptoms of CVS can include eye strain, headaches, fatigue, burning, loss of focus, blurred vision, double vision or head and neck pain. This syndrome has been widely recognized in the adult population for many years.
The AOA encourages students to rest their eyes by following the 20-20-20 rule: take a 20 second break every 20 minutes and look at something 20 feet away.
This may be easier to enforce when your children are studying than when they are playing video games… but try anyway!!
