Can myopic person get presbyopia after all??

Abstract: there is a certain limit to the degree of aging. Generally speaking, the degree of aging of each person is about 300 degrees to 400 degrees. This is the vast majority. With the growth of age, the degree of presbyopia will increase by 50 degrees every three years, but it will not increase when it reaches the degree of 300 degrees or 400 degrees. Why does

have presbyopia?

and

presbyopia are mainly caused by the gradual rigidity of the elasticity of the lens regulatory function with the increase of age, the inability of self-regulation and the decline of the regulatory ability of the ciliary muscle. Therefore, presbyopia can see clearly from a distance. Near because the lens is not elastic, it will be tired to see things, and it is not easy to adhere to it. In serious cases, it can not even be seen near.

and

people often ask: won’t people with myopia get presbyopia?

and

do not mean that people with myopia will not get presbyopia, but that people with myopia may delay the age of presbyopia.

this is mainly because people with myopia often wear glasses. Glasses are concave lenses, which are negative degrees, while patients with presbyopia may have to wear convex lenses, which are positive degrees. Positive degrees and negative degrees offset each other, and the symptoms of Laohua are not obvious, but in fact, the ciliary muscle has changed.

once the degree of presbyopia exceeds the degree of myopia, presbyopia will appear obviously. Will the degree of presbyopia of

and

increase year by year? The degree of

and

old flowers has a certain limit. Generally speaking, the degree of aging of each person is about 300 degrees to 400 degrees. This is the vast majority. With the growth of age, the degree of presbyopia will increase by 50 degrees every three years, but it will not increase when it reaches the degree of 300 degrees or 400 degrees. Therefore, the degree of presbyopia is often stable after the old man reaches the age of 65 or 70. Therefore, presbyopia patients should change their glasses every two or three years. After its degree is stable, it doesn’t need to be replaced frequently.
