What is the difference between axial myopia and refractive myopia?

Abstract: axial myopia is the most common myopia. When the axis of the eye becomes longer, the eye will naturally become myopia. This kind of axial myopia is generally simple myopia, and many people with high myopia are accompanied by axial growth., Myopia is already a very common phenomenon, and with the increase of myopia, the number of people going to optometry and glasses is also increasing.

What is the difference between the two?

Axial myopia is the most common myopia. When the axis of the eye becomes longer, the eye will naturally become myopia. This kind of axial myopia is generally simple myopia. Many people with high myopia are accompanied by axial growth., Axial myopia generally refers to that other refractive components are basically normal, but the eye axis increases. When the parallel light enters the eye, it focuses in front of the retina, forming myopia, resulting in blurred vision from a distance. When the eye axis increases by 1 mm, the degree of myopia increases by 300 degrees., Refractive myopia refers to the myopia caused by the change of refractive factors such as lens within the normal range. The refractive components of the eye are abnormal, or the combination of components is abnormal. The parallel light enters the eye and focuses in front of the retina after refraction by the refractive system to form myopia.

difference between axial myopia and refractive myopia?

There are two main types of refractive myopia.,

One is curvature myopia, which is caused by the increased curvature of the cornea or lens surface, which changes the curvature shape and shortens the radius of curvature, resulting in parallel light entering the eye and focusing in front of the retina., The other is refractive index myopia, which is mainly caused by the increase of refractive power caused by the increase of refractive index of aqueous humor and lens., Refractive myopia is mainly affected by ophthalmic diseases and other factors, which affect the refractive rate and lead to the formation of myopia.,

myopia is a very common phenomenon, and with the increase of myopia, the number of people going to optometry and glasses is also increasing. In the optometry matching glasses, although they are all myopia, the types of myopia are different. Some people are myopia with astigmatism, while others are simple myopia. In the types of myopia, axial myopia and refractive myopia are often heard. What is the difference between the two?

Axial myopia is the most common myopia. When the eye axis becomes longer, the eye will naturally become myopia. This axial myopia is generally simple myopia, and many people with high myopia are accompanied by axial growth.

Axial myopia generally refers to that other refractive components are basically normal, but the eye axis increases. When the parallel light enters the eye, it focuses in front of the retina, forming myopia, resulting in blurred vision from a distance. When the eye axis increases by 1 mm, the degree of myopia increases by 300 degrees.

Refractive myopia refers to myopia caused by the change of refractive factors such as lens within the normal range. The refractive components of the eye are abnormal, or the combination of components is abnormal. The parallel light enters the eye and focuses in front of the retina after refraction by the refractive system to form myopia.

Refractive myopia is mainly caused by ophthalmic diseases and other factors affecting the lens, affecting the refractive rate and leading to the formation of myopia.

Whether axial myopia or refractive myopia, it is generally true myopia and needs myopia correction. For teenagers, axial myopia is the most. Even if you have glasses, you should pay attention to health, use your eyes to protect your eyes, and do corresponding vision health care to slow down the development of myopia.
