Is astigmatism congenital?

　　Astigmatism is categorized into regular and irregular types. Regular astigmatism can be corrected with eyeglasses, whereas irregular astigmatism cannot be adequately corrected with standard spectacles. Is astigmatism congenital?

　　Is Astigmatism Congenital?

　　Some cases of astigmatism are indeed congenital. However, other cases arise from acquired factors; therefore, a comprehensive evaluation—including the patient’s age at onset, symptoms, and presence of other ocular conditions—is essential for accurate diagnosis. Congenital astigmatism, also termed physiological astigmatism, occurs when infants are born with corneal developmental abnormalities or other congenital eye disorders, resulting in an irregular corneal shape and consequent astigmatism. In some children, this astigmatism may progressively worsen with age and even lead to amblyopia. Nevertheless, the majority of astigmatism cases are not congenital; rather, they are primarily associated with individual visual habits, corneal pathology, myopia, and similar factors. Most cases of astigmatism can be effectively corrected through refraction testing and appropriate spectacle prescription.

　　Maintain a balanced diet—especially during adolescence—and avoid picky eating, as nutritional imbalances may adversely affect vision. Consume foods rich in beta-carotene and zinc to enhance ocular resistance and accommodative function. Individuals considering corrective lenses for myopia or hyperopia should not undergo refractive examinations casually; instead, they should visit reputable hospitals or ophthalmology clinics for professional refraction. If astigmatism is present, correction must include the appropriate cylindrical power.

　　In daily life, cultivate healthy lifestyle and dietary habits. We hope this information proves helpful to you.
