Refractive errors in children can be treated by wearing frames and using keratoplasty lenses to improve vision. Refractive error in children is a common ophthalmologic condition, usually caused by a combination of congenital developmental abnormalities and poor eye habits, and can be diagnosed through an optometric examination. The most common treatment for refractive error in children is to wear frames, which are inexpensive, safe, convenient and easy to use, and are currently the most widely used form of correction. The use of keratoplasty lenses is a new method that has emerged in recent years. While correcting refractive error, it can also stop and slow down the growth of refractive error by eliminating the phenomenon of peripheral defocus. It is recommended that refractive error patients seek medical attention to evaluate their condition and follow the doctor’s instructions.
