Astigmatism in children does not heal on its own and needs to be corrected on a case by case basis. Astigmatism is usually congenital, caused by irregularities in the cornea during the development of the eye, and does not heal on its own. If the astigmatism is low, around 50 degrees, it is a physiological astigmatism, which does not affect the vision greatly, and although it does not heal itself, it does not need to be corrected. If the astigmatism is deeper or affects vision, blurred vision, visual fatigue, squinting, and serious double vision, frame glasses or hard contact lenses are needed to correct the problem. If there is a previous history of eye trauma, keratitis, etc., corneal scarring usually forms resulting in irregular astigmatism, which also cannot be recovered because of the non-fading corneal scarring. When astigmatism appears, you can review it regularly at the ophthalmology department to know the degree of astigmatism development. Don’t play cell phones, lie down and read books, squint for a long time in daily life, which aggravate eye fatigue and thus deepen astigmatism.
