Abstract: genetic factors play an important role in the occurrence and development of myopia. The analysis of relevant survey results shows that the rate of myopia in family members with a family history of myopia is higher than that without a family history of myopia.
as a “big country” of myopia, more and more people suffer from myopia. Students and office workers are all wearing a pair of heavy glasses. Because myopia is becoming more and more common, many people also think that myopia is just that they can’t see clearly.
and in fact, myopia, as an “eye disease”, will cause trouble and harm to your life! What are the hazards of myopia? Can myopia be inherited?
five hazards of myopia
1. Drag down the efforts of learning
by 30%. The phenomena of blurred vision, dry and sore eyes, difficulty in concentrating, irritability and even dizziness caused by myopia will make children spend 30% more time and mental labor on learning than children with normal vision.
2. Affect the appearance
myopia will lead to eye changes. Medium and high myopia will lead to exophthalmos, eyelid relaxation and affect appearance.
three, the degree deepened
developed into high myopia. When a child is nearsighted, he is anxious to match glasses, but ordinary nearsighted glasses have no corrective effect. After wearing glasses, the child can see the distance, but when reading and writing at a close distance, the myopia lens aggravates the burden of using the eyes.
IV. nearly 30 majors such as
electronic information, bioengineering, Medical Pharmacy, flight and navigation technology are limited. Every year, a large number of candidates are excluded from the major because of myopia, which seriously affects their children’s life and career planning.
generations have become slaves of glasses. Genetic factors play an important role in the occurrence and development of myopia. The analysis of relevant survey results shows that the rate of myopia in family members with a family history of myopia is higher than that without a family history of myopia. Both parents are high myopia patients, and the incidence of high myopia in their children is 100%. If one of the parents is highly myopic, If the other party is a gene carrier (no myopia), the expected incidence of children’s high myopia is 50%; if both parties have no high myopia and are only gene carriers, the incidence of children’s high myopia is 25%.
[“three needs” and “four don’t”]

1. Reading and writing posture should be correct, and the distance between eyes and books should be about 33 cm;
2. Read and write continuously for 30 minutes to 1 hour, take a break or look into the distance for a while;
3. Do eye exercises carefully.
1 Do not read or write in dim light or direct sunlight;
2. Don’t read while lying in bed and walking;
3. Don’t read books with too small and dense fonts and unclear handwriting;
