Lazy eye, or amblyopia, is diminished vision in one eye that can stem from a number of causes. If left untreated, the brain will eventually begin to ignore the images from the lazy eye and that could lead to permanent vision problems.
This study found younger children showed a better response to the various treatments in both moderate and severe cases of lazy eye.
But scientists also determined older children, ages 7 to 13, a group they didn't think was as treatable, did find moderate benefits.
