Relationship between axial length and myopia

There is a close relationship between axial length and myopia.

Axial length refers to the length of the eyeball from front to back, while myopia refers to a refractive error in which the eye is clear when looking at near and blurred when looking at distance. Increased axial length is one of the main factors in the development of myopia. When the axial length is too long, the refractive system of the eye cannot accurately focus light on the retina, resulting in myopia. Therefore, there is a positive correlation between axial length and myopia, that is, the longer the axial length, the higher the degree of myopia.

Although axial length is an important factor in myopia, it is not the only factor. Other factors such as corneal curvature and lens thickness may also affect the occurrence and development of myopia. Therefore, many factors need to be considered comprehensively when preventing and treating myopia.
