Lazy
Eye
Lazy Eye occurs when the visual information from one eye is different from
that of the other. This variance can happen when strabismus causes
the eyes to point in different directions, or when the eyes go about refraction
differently, i.e.: one eye is nearsighted
and one is farsighted. Strabismus
is a visual defect in which one eye cannot focus with the other on an object
because of imbalance of the eye muscles. This condition can result
in double vision. To compensate for this inconvenience, the brain
cancels the weaker image of the two. Over time, the unused eye becomes
weaker and cannot be fully corrected even when a corrective lens is placed
before it. When a healthy eye cannot be fully corrected to 20/20
vision, it is called lazy eye or amblyopia.
Four million people are affected by lazy eye in the United States.
Lazy Eye usually develops in a child's first few years and rarely develops
in adults. Almost 100% of the cases of lazy eye can be corrected if the
condition is detected early in childhood.
