Refractive errors are indeed the most common type of vision problem in children. This category includes conditions like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, all of which occur when the shape of the eye prevents light from focusing directly on the retina. These conditions can significantly affect a child’s ability to see clearly at various distances, which can impact their learning and daily activities.

Recognizing and addressing refractive errors is essential for children's overall development and educational success, as untreated vision problems can lead to difficulties in school and can affect their self-esteem. Screening for these issues is a routine part of pediatric healthcare, ensuring early identification and intervention.

While other options like color blindness, strabismus, and night blindness do occur in children, they are less prevalent than refractive errors. Color blindness is predominantly a genetic condition affecting a smaller portion of the population, while strabismus, which involves misalignment of the eyes, and night blindness, related to poor vision in low light, are also less common compared to the broad spectrum of refractive errors encountered in the pediatric population.
