Introduction
If a child has regular astigmatism, it will not impair visual acuity and, in the absence of visual fatigue, does not require treatment. However, if a child experiences visual fatigue—even with very mild astigmatism—cycloplegic refraction is necessary, followed by prescription and wear of appropriate corrective lenses. If the degree of astigmatism is too high for the child to tolerate initially, low-power corrective lenses may be prescribed first, allowing gradual adaptation.
Astigmatism is a common and frequently occurring ophthalmic condition affecting individuals of all age groups, with a relatively higher incidence among children. In children, astigmatism not only compromises ocular health but can also significantly reduce visual acuity and even interfere with learning. So, what should be done if a child has astigmatism?
What to Do If a Child Has Astigmatism
If a child has regular astigmatism that does not impair vision or cause visual fatigue, no treatment is required. However, if the child experiences visual fatigue—even with very mild astigmatism—cycloplegic refraction (dilated eye examination) must be performed, followed by prescription and fitting of appropriate corrective spectacles. If the degree of astigmatism is too high for the child to tolerate initially, low-power corrective lenses may be prescribed first to allow gradual adaptation before progressing to higher-power lenses.
Improper eye posture can significantly exacerbate astigmatism. Therefore, individuals with astigmatism must promptly correct their eye posture and avoid developing poor habits—such as reading or using mobile devices while lying down or reclining, or reading in a moving vehicle. It is recommended to sit upright, maintaining a distance of 30–40 cm between the eyes and reading material. Prolonged fixed gaze increases ocular fatigue and may accelerate tear evaporation, leading to dryness and discomfort in the eyes.
Individuals with astigmatism should take care to avoid eye strain in daily life. Screen time should be minimized, especially avoiding smartphone use or reading in dark environments, as these activities readily induce visual fatigue. We hope this information proves helpful.
