What Are The Causes Of Myopia

Influence of genetic factors

Myopia has been recognized to have a certain genetic tendency, especially for high myopia, but this tendency is not very obvious for general myopia. Those with genetic factors have an earlier age of disease, and the degree is more than 600 degrees. However, there are also patients with high myopia who have no family history. High myopia belongs to autosomal recessive inheritance. Generally, myopia belongs to a multifactorial genetic disease.

Too little time outdoors

The number of children watching TV, playing mobile phones and playing computers increases, which leads to eye fatigue and affects the normal development of the eyes.

Parents should take their children to go out for a walk, they can take a breath of fresh air, and they can also adjust their children's eyes to relax their eyes.

Scientists have found that children who often go out to play sports are much less likely to be short-sighted than children who stay at home all day.

Excessive exposure to electronics too early

The widespread use of computer, TV and mobile phones is one of the important reasons for the high incidence of myopia in children and the trend of younger age.

The harmful high-energy blue light emitted by electronic product screens will accelerate the decline of retinal cells, cause visual fatigue, and even cause myopia and more serious eye diseases.

not getting enough sleep

Children who sleep less are more prone to myopia. During the period of rapid growth and development of children, especially at the age of 7-9 and 12-14 years old, if there is less sleep time, it will cause some children to develop myopia.

eye environment

Reading in places where the light is too bright, too dark, glare, or reflections will adversely affect vision. If the light is too strong, it will cause strong reflections, irritate the eyes, make the eyes uncomfortable, and make it difficult to see the font.

When the light is too weak, the writing is insufficiently illuminated, and the eyes cannot read the font clearly, the head will move forward and close to the book, both of which will lead to eye fatigue, over-accommodation or spasm, resulting in myopia.

scleral hypotrophic factors

Due to the long-term vision of the eye, the ciliary muscle is in a state of contraction and tension for a long time, which makes the choroid stretch and tense, blood flow decreases, blood volume is insufficient, and scleral nutrition begins to decline.

Later, abnormal growth of the eye axis occurs.

Children's vision problems should not be underestimated. Before the child develops true myopia, treat falsehoods and prevent trues, and give your children more care and patience for a bright future.
