Is high myopia really hereditary?

Because of severe myopia, your partner’s parents advised you to break up?

Myopia is over 600 degrees, and you are rejected when you go on a blind date? "Parents are highly myopic and the one-year-old baby has 600 degrees of myopia!" The recent hot search has touched the hearts of friends with high myopia again.

"I heard that myopia is hereditary, so I want to find a partner who is not myopic?" "Only high myopia is hereditary, but acquired myopia is not hereditary?"

Myopia is becoming more and more common and younger. Is it really because of heredity that makes the number of people with myopia snowball? Or is it because of environmental factors that make myopia inevitable?

Today’s Q&A✔ : Will myopia be passed down to children?

Myopia is not directly inherited.

But it will increase the possibility of myopia

Myopia is divided into simple myopia and pathological myopia . Simple myopia is also called acquired myopia ; while pathological myopia refers to myopia with a high degree of myopia accompanied by obvious fundus degeneration and other complications.

Among the more common myopia, simple myopia is more common , that is, acquired myopia, which is affected by both genetic and environmental factors. Unlike pathological myopia, the inheritance of acquired myopia belongs to polygenic inheritance, which plays a genetic role when the inducing genes are superimposed on each other.

Pathological myopia is closely related to heredity, mainly due to single gene inheritance . That is to say, among the multiple predisposing genes, as long as one of them is inherited, it will cause pathological myopia.

If we must draw a conclusion, it is possible that what is directly passed on to children is not myopia itself, but a physical constitution that makes them more susceptible to myopia.

In addition to genetic factors

Environment and habits can also cause myopia

In daily life, in addition to genetic factors, the environment is the most likely cause of myopia, including long-term close-range eye use, less time for outdoor activities, and insufficient lighting conditions.

Under the same living environment and learning intensity, those with high genetic risk may be more prone to myopia. However, this does not mean that if parents have high myopia, their children will definitely have high myopia, nor does it mean that if parents do not have myopia, their children will not have high myopia. Without genetic factors, environmental factors may also cause myopia.

Improper wearing of glasses

May cause severe myopia

The problem of improper correction of glasses is very common in daily life, which can easily lead to high myopia.

Myopia has not been corrected scientifically, such as wearing glasses with the wrong degree (either too low or too high is unscientific) .

Not wearing glasses in time (some people mistakenly believe that the later you wear glasses, the better).

These situations will cause eyes to become more fatigued and the eye muscles will be in a state of incorrect regulation for a long time. Over time, the degree of myopia will increase, making it easier to break through the 600-degree "red line" and develop into high myopia.

Genetics cannot be changed

Myopia prevention and control is more critical

Although myopia is irreversible, it can be controlled. Effective control measures can prevent the occurrence of high myopia. People with a family history of high myopia and genetic risk should undergo genetic screening at an early stage to assess the risk of high myopia, detect it in time, and prevent and control it in time to avoid the development of high myopia.

Clinical studies have shown that orthokeratology lenses, multifocal soft contact lenses, myopia prevention and control related frame glasses and low-concentration atropine have a certain myopia control effect and can successfully delay the progression of myopia.

1. Develop good eye habits; you can use the "20-20-20" eye protection method, that is, use your eyes at close range for 20 minutes, and look into the distance of 20 feet (6 meters) for at least 20 seconds.

2. Participate in more outdoor activities and try to ensure 1-2 hours of sun exposure every day.

3. Young children’s eyes are not fully developed yet, so it is not recommended for them to be exposed to electronic products at an early age.

4 It is recommended to go to a regular ophthalmology institution for an eye health check every six months.

5. If you have been diagnosed with myopia, please choose the appropriate vision correction plan based on professional advice.

Director Qin Yinyan of the Strabismus and Pediatric Ophthalmology Department of the Aier Eye Hospital affiliated to Wuhan University reminds that some parents think that myopia is common and no big deal, but high myopia can cause a series of serious eye complications; it may not only lead to permanent vision loss, but even blindness. Therefore, myopia prevention and control must be carried out as early as possible. If myopia really occurs, please do not delay and take your child to a professional ophthalmology hospital for examination as soon as possible to develop an effective myopia prevention and control management plan.
