Lazy Eye Amblyopia: What is it?

Amblyopia or “lazy eye” is a very common vision problem that we see in children. basket adidas zx flux In fact it is responsible for more vision loss in kids than all other reasons combined. adidas zx pas cher nike pas cher 2017 Amblyopia is a decrease in the child’s vision that occurs even without any structural problem being present. ugg boots pas cher The decrease in vision results when one or both eyes send a blurry image to the brain. timberland homme The brain then “learns” to only see blurry with that eye, even when glasses are used.
