What is the reason why the eye axis has not grown in degrees

The eye axis length does not increase, considering the factors such as no change in curvature, reduced corneal curvature, and no change in other structures in the eye.

1. The curvature does not change. At the same time

, if there is no increase in corneal curvature, the degree will generally not increase.

2. The decrease in corneal curvature

is balanced with the decrease in corneal curvature. If the eye axis increases, the corneal curvature will decrease, and the degree will generally not increase.

3. There is no change in other structures in the eye. If the

eye axis increases, there will be no change in other structures in the eye, such as lens and vitreous body.
