What Is Amblyopia (Lazy Eye)?
Amblyopia, commonly called "lazy eye," is a condition where vision in one eye is reduced because the eye and brain have not worked together properly during early childhood. The brain learns to rely on the stronger eye and ignores input from the weaker eye. It is the most common cause of visual impairment in children, affecting 2‑3% of the population.
When to seek care
All children should have a vision screening by their pediatrician and a comprehensive eye exam — comprehensive exam by age 3‑5. Early detection is critical — amblyopia is much easier to treat when the visual system is still developing. Adults who notice unequal vision between eyes should also be evaluated.
