People with high myopia often have low intraocular pressure, but the optic nerve has the performance of glaucoma

Abstract: because the eyeball is elongated, the water contained in the posterior vitreous body will increase accordingly, and the compressive force on the lens will increase; Coupled with the changes of some metabolic substances in the eyeball, the lens changes early.

why is it easy for people with myopia to suffer from cataract early?

A: the reason is unknown, but the fact is before us – in recent years, more and more people have developed cataract early because of high myopia.

cataract is an eye disease that causes vision loss due to lens opacity.

when light enters the eye, it needs to be refracted by the lens to reach the retina. Through the shape change of the lens, different refraction degrees are formed, so that we can see clearly from far to near, just like the “focusing” of mobile phone photography. So the lens is a very important organ in the eye!

and

lenses are transparent under normal circumstances, and light can pass through easily; Once it becomes cloudy, we will have vision problems.

and

in our daily life, we will feel that cataract is a “geriatric disease”, which only the elderly will get. In fact, there are also young cataract patients, and today, The biggest source of cataract in young people is that the ocular axis is too long (the degree of myopia is too deep).

why does myopia make cataract report early?

explanation 1: the lens is pulled

Myopia not only lengthens the eyeball, but also enlarges the width of the eyeball; The lens will also become diseased due to the pulling of the expanded eyeball. Explanation 2 of

and

: the change of substances in the eyeball

and

because the eyeball is elongated, the water contained in the posterior vitreous body will increase accordingly, and the compressive force on the lens will increase; Coupled with the changes of some metabolic substances in the eyeball, the lens changes early.

how to prevent cataract?

and

the environmental factor most likely to cause cataract is ultraviolet light.

suggestions: 1 If you are outdoors for a long time in the daytime, pay attention to the use of sunglasses; 2. Check whether your myopia glasses have anti ultraviolet (UV) function.

in addition, if the degree of myopia soars for several Baidu in a short time, you should suspect that it may be cataract and must be checked in time.
