J.I.
I also suffered from the same problem when I was very young, about 4. I had to wear glasses to strenghthen a weak eye, but I was always setting them down somewhere, and losing them.
I was always indifferent about wearing my glasses, and now I am paying the price for it at 32. My eye doctor told me, that now, I do not use both of my eyes simultaneously, the way people are supposed to. Because neither of my eyes are strong, (one from not enough use, and the other from over-use)I switch back and forth, when one is tired, the other takes over. Because of this, I am prone to light sensitivity, and severe migraines. I also suffer from nausea, and a sensitivity to sound, while having a migraine.
Please emphasize to your daughter the repercussions of not taking care of her eyes, I have suffered migraines since the age of 14, and they could have been prevented.
