I am not sure whether I am right or not, about this. Does a tablet screen can cause eye strain or headache. My niece got a 7inch tablet in gift. I had copied a number of video songs, poetry and stories in it. Now she use that tablet for a entire day. Kids really enjoy games and stories. From last couple of days she is complaining about red eye and a bit of headache also. I showed to the doctor who told her to stay away for TV screen for a while. I think the tablet is causing this.
