Amblyopia is a condition that affects sight. You may have heard of it referred to as "lazy eye." When communication between the brain and one of the eyes doesn't fully develop, the brain may begin ignoring that eye. It may even move away from its central position (although not everyone with the condition shows this physical sign of lazy eye). The neglected eye will continue to see poorly. Sight will be blurred.

Amblyopia, also known as lazy eye, is the most common eye disorder in children. In amblyopia, vision in one of the eyes is impaired because the eye and the brain are not working together properly. Amblyopia can be caused by misalignment between the two eyes (strabismus). Sometimes amblyopia develops when one eye is more farsighted or has impaired focus (astigmatic) than the other eye. In some cases vision in both eyes is impaired. This occurs when there has been ocular disease in both eyes like cataract or both eyes have large refractive errorsAmblyopia should be treated in early childhood to prevent it from becoming permanent. However, a national study led by Hopkins Children’s recently showed that even older children may benefit from treatment.
Ever heard of a failure to communicate? This defines amblyopia, a condition in which the eye and brain don't sync up, and vision suffers, even though eye structures are normal. Wearing an eye patch over the eye with normal sight could help correct vision in the "lazy" eye.
Amblyopia, commonly called "lazy eye," is an eye condition in which one eye is not used enough for the visual system in the brain to develop properly. If one eye is weak, the brain ignores the images from it and uses only the images from the stronger eye, leading to poor vision in the weak eye.
Amblyopia usually affects only one eye, but it may occur in both eyes. Children can develop amblyopia between birth and about 7 years of age.
Amblyopia can be hard to detect. A child with amblyopia may have one eye that wanders or does not move with the other eye.
Amblyopia may develop if a child is much more nearsighted or farsighted in one eye than in the other. Extreme nearsightedness or farsightedness in both eyes may lead to amblyopia. Cloudiness in the black center of the eye or a droopy upper eyelid also can lead to amblyopia.
Normal vision develops with regular, equal use of the eyes. Treatment for amblyopia includes patching the stronger eye to force the weaker eye to develop better vision. Early treatment can usually reverse the condition.

Good vision develops during childhood when both eyes have normal alignment. Strabismus may cause reduced vision, or amblyopia, in the misaligned eye.
The brain will pay attention to the image of the straight eye and ignore the image of the crossed eye. If the same eye is consistently ignored during early childhood, this misaligned eye may fail to develop good vision, or may even lose vision. Strabismic amblyopia occurs in approximately half of the children who have strabismus.
Amblyopia can be treated by blurring or patching the “good” eye to strengthen and improve vision in the weaker eye. If amblyopia is detected in the first few years of life, treatment is usually successful.
If treatment is delayed, amblyopia may become permanent. As a rule, the earlier amblyopia is treated, the better the result for vision.
