Amblyopia can result from any condition that prevents one eye from focusing clearly. Amblyopia can be caused by a misalignment of the two eyes.  This condition is called strabismus. Misaligned eyes can turn in, which is esotrpia or turn out, exotropia.

A common cause of amblyopia is the inability of one eye to focus as well as the other one. This most often occurs when one eye is more farsighted than the other. Eyes that are farsighted tend to focus better at a distance but have more difficulty focusing on near objects. 

Treatment may include patching of one eye for several hours per day, vision therapy or eye drops in one eye.  The video here describes treatment in more detail.
