I think they should have less tv time . They need to take a break play inside or out for a couple of hour’s. I think kids watch too much tv. I think the experts are right too. If you sit there long enough your eye’s will get sore and hurt if you stay there for awhile you could get blind and they could get weak that wouldn’t be good. You should at least watch tv for 30 min or 40 min if that. Or you can play inside for a little bit. Once your on Ps4 or xbox 360 or Xbox 1 or Xbox 1’s you can’t get off of them i set a timer for my xbox1.
