Parents must watch! The super comprehensive guide to children's vision screening is here.

Babies' eyesight problems vary greatly with their age.

4-6 months: Beware of strabismus. Strabismus is always accompanied by crooked neck. If the baby has this kind of performance, consult an ophthalmologist in time.

After 6 months: you can do refractive screening to determine whether there is astigmatism, high myopia, hyperopia, etc.

2-2.5 years old: Some hyperopia children are prone to cross-eye. It is necessary to consider whether there is conditional varus through astigmatism and judge whether it needs correction.

3 years old: Generally, a 3-year-old child can cooperate with the eye axis to prevent myopia.

4-6 years old: if there is no problem with the above examination, it is mainly myopia prevention and control.

What can parents do besides routine screening?

0-3 years old is the critical period of visual development, and 3- 10 years old is the sensitive period. In these two important stages, careless eye habits, lack of outdoor activities and insufficient vitamin A intake are the main factors leading to abnormal vision of children.

In addition, calcium also has a clear role in protecting eyesight. Calcium can increase the regulation ability of eye muscles, effectively avoid eye fatigue and reduce the risk of myopia. Therefore, as a key nutrient for calcium absorption, adequate vitamin D is also necessary.

However, vitamin A and vitamin D are the two nutrients that babies are most likely to lack. The latest large sample epidemiological data shows that the overall lack rate of children aged 6 months to 14 years in China has reached 47.98%, and the younger they are, the higher the lack rate is. The proportion of vitamin D deficiency is also over 50%. In order to meet the needs of children's growth and development, promote vision development and prevent myopia, the baby should be supplemented with vitamin A 1500IU-2000IU and vitamin D400IU-800IU every day after birth. It is very necessary to take one tablet of Iconoxin every day, at least until the age of 3. It is ideal to continue to supplement in the critical period and sensitive period of vision development.
