Lazy eye
A lazy eye (amblyopia) is a childhood condition where the vision in one eye doesn't develop properly. This usually means that the child can see less clearly out of the affected eye and relies more on the "good" eye.
A lazy eye (amblyopia) is caused when something disrupts the normal development of vision. It's often assumed that younger children have the same vision as adults, but this isn't the case.
A lazy eye (amblyopia) ideally needs to be diagnosed and treated as early as possible, preferably before a child is five years of age. However, it can often be difficult to know whether a child has a lazy eye as they might not realise anything is wrong with their vision.
Alazy eye (amblyopia) is often diagnosed and treated by an orthoptist under the supervision of an ophthalmologist. The younger the child is when a lazy eye is diagnosed, the more successful treatment is likely to be.
