Corneal curvature is somewhat high and myopia is related

Corneal curvature

refers to the radius of curvature of the anterior and posterior surfaces of the cornea, and corneal curvature has a certain relationship with myopia. Myopia can be divided into axial myopia and refractive myopia. Refractive myopia is caused by excessive refractive power of the cornea or lens beyond the normal range. If the patient's corneal curvature is higher, the radius of curvature is shorter, and the parallel beam will focus on the front of the retina prematurely. Myopia will be more obvious. In addition, myopia is also related to the length of the eye axis and refractive index. If the patient's eye axis grows or the refractive index of aqueous humor and lens increases, it will also cause light to focus on the front end of the retina prematurely, forming myopia.
