is reduced even with glasses. Amblyopia is the commonest cause of vision
problems in children, and develops sometime between birth and 8 or 9 years of
age, the critical period of time when the visual system develops and matures.
Amblyopia causes more visual loss in the age group under 40 than all the

occurs when the nerve connections between the brain and the eye fail to develop
normally. Vision problems such as short sightedness, long sightedness or
astigmatism, if uncorrected can cause amblyopia.
The amblyopic eye may develop a permanent visual
defect and depth perception (seeing in three dimensions) may be lost. If the
stronger eye becomes diseased or injured, it can mean a lifetime of poor

Early detection of the
condition increases the chance of successful treatment, especially if it is

poor depth perception.
