Treatment of amblyopia ('lazy eye') depends on the underlying cause.

If the amblyopia is caused by squint (or strabismus), the stronger eye may be patched, or covered, in order to make the amblyopic eye work harder.

If the cause is very short or long sight in one eye, spectacles are prescribed, sometimes with patching.

If the amblyopia is due to an ocular problem such as cataract, that condition will need to be treated.

After therapy the patient may require spectacles or contact lenses to restore focusing.
