Abstract: genetic factors play a great role in high myopia. However, myopia is not a simple genetic disease, it will be affected by a variety of genes. It will also be affected by external environmental factors.
myopia above 600 degrees is called high myopia. Some people don’t think highly myopia is high, and they don’t understand the harm of high myopia. These 8 pieces of common sense are for friends with high myopia.
1. The eyes of people with high myopia are elongated.
generally, the higher the degree of myopia,
the longer the eyeball will be,
the longer the anterior posterior diameter of the eyeball of patients with high myopia will be, just as the table tennis ball is pulled into the shape of an egg. (think about it, there are terrible trees)
so, this leads to the fact that the light can not accurately gather on the retina of the fundus, causing us to see things vaguely.
2. High myopia is related to heredity.
genetic factors play a great role in high myopia. However, myopia is not a simple genetic disease, it will be affected by a variety of genes. It will also be affected by external environmental factors. Therefore, if parents with high myopia have long planned to protect their children’s eyesight, it is not easy to think of high myopia; Even if you are not highly myopic, your next generation may also be highly myopic.
3. Try not to exercise violently for high myopia
if you are high myopia, you should avoid strenuous exercise, especially the activities that have direct impact or obvious concussion on the eyes and head. Diving or bungee jumping, boxing, high jump, or even some violent shaking games in the amusement park, etc. ~ basketball, football, badminton and other sports can basically be carried out.
4. People with high myopia are more likely to have fundus diseases.
people with high myopia are more likely to have fundus retinopathy. These diseases may also cause blindness! Some can be prevented and treated by laser or surgery in time, while others do not have good treatment. Their eyesight may become very poor, and wearing glasses does not work.
5. High myopia is suitable for wearing aspheric thin lenses with high refractive index. Myopia glasses with
height are thicker and heavier, visual deformation is also obvious, and dizziness and other discomfort are easy to appear. It is generally recommended to use aspheric thin lenses with high refractive index.
6. The visual effect of wearing contact lenses for high myopia is better, but don’t wear
for a long time. Compared with frame glasses, contact lenses are close to the eye, which will not cause visual deviation like frame glasses optically, and the visual effect is much better, It is a better choice for high myopia (but it is not suitable for long-term wearing).
7. High myopia can be treated surgically with
If adult patients do not want to wear glasses, they can also consider myopia correction surgery. Excimer laser, femtosecond, ICL crystal implantation and other surgical methods, which is suitable for, we should do a detailed preoperative examination. At present, the highest case in China is a 3600 degree Zhangzhou young man, who uses ICL crystal implantation.
8. The best way to prevent high myopia is to exercise more outdoors. The best way to prevent
is to develop good eye habits from childhood and exercise more outdoors to avoid stepping into the ranks of “high myopia”.
