Amblyopia, commonly known as ‘lazy eye,’ is a condition where one eye has reduced vision due to the brain favoring the other eye. It often develops in childhood and can lead to permanent vision impairment if left untreated. Early diagnosis and treatment are crucial as the brain can learn to ignore the weaker eye, impacting depth perception and overall vision. Timely intervention, such as corrective glasses, eye patches, and sometimes surgery is important to prevent long-term visual impairment and help the affected eye develop normal vision.
