The difference between amblyopia and low vision 

Some experts of special education sector, some Hong Kong and Taiwan as well as some translations of books low vision often called amblyopia, in fact, these are two different concepts. 

Amblyopia refers to the eye itself without structural change, or, though organic changes and refractive errors, but vision loss and lesions are incompatible and can not be corrected by. 

Some people think: Where no structural damage to the eye corrected visual acuity less than 0.4, or two visual differences ≥3 Walker as amblyopia. 

Our children amblyopia, strabismus Prevention Study Group in October 1987, on the basis of reference on various definitions put forward: Where eye without organic disease, in order to function mainly caused by factors far vision values below 0.9 and can not be correction who are classified as amblyopia. 

Simply speaking, amblyopia refers to the eye from the appearance and health of the human eye, fundus examination could not find any visual impact of the cause, they do not get after optometric vision correction, and check to see that the cause of poor vision in the eye. 

Low vision means that, for whatever reason, whether it is eye diseases, eye injury or brain disease, as long as the gifted eye corrected visual acuity between 0.3-0.05, it is called low vision. 

Thus: low vision and amblyopia are two different concepts. Amblyopia is closely related to the development of an eye, like strabismus, myopia, as that can lead to poor vision. Low vision is a description of a person's visual acuity is a function of the state. Children with low vision are not caused by amblyopia, thus the two can not be confused.
