I wanted to share my experience with you, even though my child is a little older (4 years old). Recently at the pediatrician, he failed the vision chart, as he could not make out what some letters/shapes were. The dr. recommended bringing him to an optometrist ASAP. The same week, I brought him to my optometrist, who also specializes in care of children. It turns out that his eyesight is not as bad as the pediatrician predicted (he had said it was 20/70 without correction); the optometrist thoroughly tested him and said it is 20/30-20/35 without correction due to astigmatism. He said that the astigmatism is something you are born with as it affects the shape of your cornea (we do have a significant family history of this as well). He said that without wearing eyeglasses, my child would not be able to see things properly. So he ordered eyeglasses to be worn at all times. The problem I am having now is that my child is refusing to wear them sometimes and we constantly have to prompt him. Sometimes when we are looking away from him, he will take the eyeglasses off and hide them under sofa cushions, etc.
Best of luck to you and your daughter.
