Mild astigmatism does not affect vision and usually does not require special treatment, whereas moderate to high astigmatism can cause vision loss in children, which can be corrected with prescription lenses to improve vision and can be treated with surgery in adulthood. Astigmatism in children is a refractive error that occurs when the refractive power of the eyeball varies at different meridians, causing light rays entering the eye to not focus to a certain point and thus fail to form a clear image of the object. Children with astigmatism can improve their vision by wearing glasses to correct their astigmatism. When children with astigmatism reach adulthood, they can have their astigmatism corrected by surgery, such as corneal laser surgery or posterior chamber lens implantation in lens-bearing eyes, if they are willing to remove their lenses. It is recommended that children with astigmatism consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions for treatment, so as to avoid affecting the development of the child’s vision.
