A child’s eye of 4.6 is not necessarily nearsighted; 4.6 is the value on the visual acuity chart and cannot be converted to a refractive error. Generally speaking, the presence of astigmatism, myopia and other conditions in children may further affect the value of the vision chart examination. Therefore, when a child has a 4.6 visual acuity reading, he or she should not be labeled as nearsighted. You can take your child to the ophthalmology department of the hospital and make a judgment by dilating the pupils of the eyes. Because children’s eyes have a strong ability to regulate, the use of dilated eye drops can paralyze the ciliary muscle to lose the ability to regulate, and thus obtain a more accurate refractive error. If a child’s dilated pupil examination results are abnormal, it is recommended to consult a doctor in a timely manner, with the help of a doctor to clarify the cause of the disease, and to carry out targeted treatment or therapy.
