What is a common cause of amblyopia in children?

A common cause of amblyopia in children is uncorrected refractive errors. Amblyopia, often referred to as "lazy eye," occurs when the brain favors one eye over the other, leading to reduced vision in the weaker eye. Uncorrected refractive errors, such as nearsightedness, farsightedness, or astigmatism, can prevent an eye from focusing properly, resulting in a lack of clear visual input. If these errors are not addressed with appropriate corrective lenses, the brain may not develop proper visual pathways for that eye, leading to amblyopia. Early detection and correction of these refractive errors are crucial to prevent the development of amblyopia and to ensure normal visual development in children.

In contrast, although excessive screen time might strain the eyes, it is not a direct cause of amblyopia. Wearing contact lenses, when prescribed correctly, can actually correct refractive errors and reduce the risk of amblyopia. Engaging in outdoor activities promotes healthy eye development, typically helping to prevent vision problems rather than causing them.
