Abstract: it is reported that in daily life, there are indeed myopia patients who will find that when they reach a certain age, the degree of myopia will be inexplicably reduced. To explain these phenomena, we must first make a general understanding of our eyes., Recently, a reader asked “I have more than 300 degrees of myopia and intend to have myopia surgery, but a friend said that people have myopia when they are young, and they will not be myopia or presbyopia when they are old. Is this correct?”. On this issue, the reporter visited Zhao Xiaohu, a consultant of our newspaper’s ophthalmologist Advisory Group and a laser myopia surgeon., Dr. Zhao believes that this statement about the relationship between presbyopia and myopia is completely groundless. It is reported that in daily life, there are indeed myopia patients who will find that when they reach a certain age, the degree of myopia will be inexplicably reduced. To explain these phenomena, we must first make a general understanding of our eyes., Our eyeball is similar to an optical camera. Refractive media such as cornea and lens of the eye are like the lens of the camera, and the retina is like the negative film in the camera. Myopia occurs because the refractive system of our eyes, such as cornea and lens, is not enough to clearly focus external objects on the retina. However, with the increase of age, the elasticity of the lens decreases, which limits the function that can be adjusted at will, resulting in the limitation of seeing far and clearly, while reading and other close eyes., It is reported that presbyopia is an inevitable physiological change. Generally speaking, presbyopia will gradually appear after the age of 40. Some people who happen to have the same degree of myopia as their presbyopia find that they don’t need to wear presbyopia glasses because the refractive state after taking off their myopia glasses is equivalent to adding a convex lens, so it will be more comfortable to read after taking off their myopia glasses, but this doesn’t mean that they don’t have “presbyopia”. Some myopia patients will offset part of myopia with the change of refractive index of crystal after reaching a certain age. The feeling is that myopia disappears with age. But in fact, the duration of this refractive change is usually very short, and “myopia” will still appear after a period of time.,
a few days ago, a reader asked “I have more than 300 degrees of myopia and intend to have myopia surgery, but a friend said that people have myopia when they are young, they will not be myopia when they are old, and they will not get presbyopia. Is this statement correct?”. On this issue, the reporter visited Zhao Xiaohu, a consultant of our newspaper’s ophthalmologist Advisory Group and a laser myopia surgeon.
Dr. Zhao believes that this statement about the relationship between presbyopia and myopia is completely groundless. It is reported that in daily life, there are indeed myopia patients who will find that when they reach a certain age, the degree of myopia will be inexplicably reduced. To explain these phenomena, we must first make a general understanding of our eyes.
our eyeball is similar to an optical camera. Refractive media such as cornea and lens of the eye are like the lens of the camera, and the retina is like the negative film in the camera. Myopia occurs because the refractive system of our eyes, such as cornea and lens, is not enough to clearly focus external objects on the retina. The old flower is because with the increase of age, the elasticity of the lens decreases, which limits the function that can be adjusted at will, so that it can see far and clearly, while reading and other close eye use are limited.
it is reported that presbyopia is an inevitable physiological change. Generally speaking, presbyopia will gradually appear after the age of 40. Some people who happen to have the same degree of myopia as their presbyopia find that they don’t need to wear presbyopia glasses because the refractive state after taking off their myopia glasses is equivalent to adding a convex lens, so it will be more comfortable to read after taking off their myopia glasses, but this doesn’t mean that they don’t have “presbyopia”. Some myopia patients will offset part of myopia with the change of refractive index of crystal after reaching a certain age. The feeling is that myopia disappears with age. But in fact, the duration of this refractive change is generally very short, and the situation of “myopia” will still appear after a period of time.
