What to do if myopia is inherited
In recent years, myopia has become increasingly serious worldwide, especially among the adolescents. According to statistics, the myopia rate among Chinese adolescents has exceeded 50%, and genetic factors occupy an important position in the onset of myopia. Many parents are worried that their myopia will be passed on to their children. So, what should I do if myopia is inherited? This article will combine popular topics and hot content in the past 10 days to give you detailed answers.
1. Scientific basis for the inheritance of myopia
Myopia is indeed hereditary. Studies have shown that when both parents are myopic, the probability of myopia in children will increase significantly. The following are the relevant data on myopia inheritance:
| Myopia of parents | Myopia probability of children |
|---|---|
| Neither myopia of parents | About 20% |
| Myopia of one parent | About 40% |
| Myopia between parents | About 60% |
It should be noted that genetics is only a factor of myopia, and environmental factors (such as eye habits, light time, etc.) are also important.
2. How to prevent hereditary myopia
Although genetic factors cannot be changed, scientific methods can significantly reduce the risk of myopia in children. Here are the precautions that have been discussed in the past 10 days:
| Preventive measures | Specific methods | Effect |
|---|---|---|
| Increase outdoor activities | At least 2 hours of outdoor activities per day | Reduce myopia risk by 30%-50% |
| Control eye time | Rule 20-20-20 (see 20 feet away for 20 seconds every 20 minutes) | Relieve eye fatigue |
| Balanced diet | Supplement vitamins A, D, calcium and other nutrients | Promote eye health |
3. Intervention methods for myopia genetics
If the child has already shown signs of myopia, intervention measures should be taken in a timely manner. The following are recent hot intervention methods:
| Means of intervention | Applicable age | Effect |
|---|---|---|
| Corneal resizing mirror (OK mirror) | Over 8 years old | Delay myopia progression by 50%-60% |
| Low concentration atropine eye drops | Over 6 years old | Delay the progression of myopia by 30%-50% |
| Multifocal contact lenses | Over 12 years old | Delay the progression of myopia by 30%-40% |
4. Parent FAQs
Here are some of the most concerned issues for parents in the past 10 days:
1. Will myopia be 100% inherited?
Won't. Even if both parents are myopic, the child may not be myopic, but the probability is higher. The key lies in the acquired eye habits and environment.
2. What age does the child need to check his vision?
It is recommended to start regular vision checks from the age of 3, especially for children whose parents are myopic.
3. Can diet therapy prevent myopia?
Dietary therapy can only be assisted and cannot be completely prevented. Comprehensive measures such as outdoor activities and eye hygiene should be combined.
5. Summary
Although myopia is uncontrollable, through scientific prevention and intervention, it can completely reduce the risk of myopia in children or delay the progression of myopia. Parents should pay attention to their children's eye health, regularly check their vision, and take comprehensive measures to protect their vision. Remember, inheritance is just a possibility, and acquired efforts are the key!
