When we talk of binocularity we refer to the use of both the eyes together. This means that the two eyes can work together as a single unit and relay images to the brain. The direct result of this is depth perception - which is the judgment of the distance a person or object is from us.
Squint needs to be rectified at an early age as this can improve our depth perception and there is no permanent loss of this function.
What happens when one operated at an older age, maybe once a person is an adult ? Research has shown us that even in an older age, the depth perception can be preserved and improved. So when we operate on a squint at an older age, when he or she is an adult there are two benefits of the surgery - not only does the individual have better cosmetic appearance, the person also regains most of the depth perception.
So it is worth correction of the squint at any age.
