DD16 was diagnosed with amblyopia, the technical term for lazy eye, when she was 9. The pediatrician picked it up and referred us to a pediatric opthamologist. Here's my $.02....because it is a medical condition, it is covered under your medical insurance. We do not have vision insurance because it's cheaper to buy her glasses than pay the premiums. DD wore a patch on one eye for a little while to help strengthen the eye, but only under the care of her physician.
Good luck with everything.
