My daughter is 9 yrs old and in the third grade. She is complaining that she can only see the color orange out of her right eye. Everything has an orange tint, as though she is looking through dark orange sun glasses. We talked to the school nurse and she had no answers to give us. This is the same eye that we had checked 1 month ago for vision. Left eye is 20/20, Right eye 20/40. Could this have anything to do with the problem my daughter is having?
