A study called the Early Glasses Study is looking at how wearing glasses early on can help prevent problems like amblyopia (lazy eye) and a condition called accommodative esotropia in young children.
They checked the eyes of 742 kids aged about 14 months and found that only a small number had high enough refractive errors to participate in the glasses test.
The results showed that while strabismus (crossed eyes) was common, very few kids had amblyopia, which suggests that this eye problem might develop later than what experts previously thought.
