Can astigmatism heal on its own?

Astigmatism usually cannot resolve on its own. Physiological astigmatism in children may remain stable over the long term, while astigmatism in adults or pathological astigmatism in children generally persists and may even worsen in some cases, requiring intervention depending on the situation. The details are as follows:

Mild physiological astigmatism may occur during childhood, mostly due to incomplete development of the eyeball. If the refractive error is low and does not affect visual development, it may remain stable as the eye matures. Although it does not self-correct, it typically does not significantly worsen, and regular monitoring is sufficient without immediate correction. However, if the astigmatism is pathological—caused by conditions such as corneal disease or ocular trauma—the degree may gradually increase, interfering with visual development and requiring timely intervention.

In adults, eye development is complete, and astigmatism is mostly caused by irregularities in the shape of the cornea or lens. Such structural abnormalities cannot correct themselves, so astigmatism usually remains stable and does not resolve spontaneously. Poor visual habits over time—such as squinting or prolonged screen viewing—may exacerbate eye fatigue and make symptoms related to astigmatism more noticeable, affecting daily life.

It is important to maintain healthy visual habits in daily life, avoiding squinting or tilting the head when viewing objects, and minimizing excessive eye strain. Vision check-ups should be conducted every six months to one year, with particular attention to monitoring changes in astigmatism in children.
