What is the medical term for the decreased vision in one or both eyes without detectable anatomic damage in the eye or visual pathways?

The correct answer is Amblyopia

Ambylopia "lazy eye" is the medical term for the decreased vision in one or both eyes without detectable anatomic damage in the eye or visual pathways. Usually un-correctable by eyeglasses or contact lenses. The disorder is due to the eye and brain not working well together. It results in decreased vision in an eye that otherwise appears normal.
