Astigmatism of 125 degrees in children is not very serious in terms of degree, but it will affect children’s vision and therefore needs to be corrected as early as possible. Astigmatism refers to a refractive error caused by various reasons such as congenital factors, bad eye habits, corneal diseases, etc. After parallel rays of light enter the eyes of children, due to the unequal refractive power of the eyeballs at different meridians, they can not converge at one point, and thus can not form a clear image of the object. From the point of view of the degree, 125 degrees of astigmatism is not very serious. However, 125 degrees of astigmatism can cause children’s visual function to decline, appearing double vision, which will affect children’s learning and life, so need to pay attention to. Children need to go to regular hospitals for optometry and visual acuity examinations, and wear appropriate glasses according to the results to correct astigmatism and improve vision. Parents should advise their children to develop good eye habits, pay attention to eye hygiene, and reduce the time they spend watching computers, TV and other electronic products to prevent their astigmatism from worsening. It is recommended that children go to the hospital in time, complete the relevant examinations and follow the doctor’s instructions for treatment.
