Are you worried about you child's eyesight? I have perfect eyesight until recently, I guess I have been working on the phone and computer too much and kids today have way too much screentime compared to when I was younger, so I am very worried for Heiley and Vegas Chan eyesight, I keep telling them to place the phone further apart but kids being kids they never listen! Thankfully I found plano app which will be doing the reminding from now on! Read this for more info http://bit.ly/2RTFhSn or you can watch this too http://bit.ly/2HID73s
