Recently, the results of the sampling survey of primary and secondary school students' vision released by the Ministry of education show that in the first half of 2020, the myopia rate of primary and secondary school students in China increased by 11.7%, especially for primary school students, the myopia rate increased by 15.2%. The detection rate of myopia within 1 hour of online class per day was 45.8%, while those over 4 hours increased to 76.7%.
Myopia is becoming more and more young, and "small glasses" emerge endlessly, affecting the hearts of millions of parents. Whether it is to watch scenery or read books and watch TV, children always use their eyes. This requires parents to help them grasp the critical period of vision development before the age of 6, and learn to use eyes correctly and scientifically to protect their eyes.
Under 1 year old: perception of change, encouraging exploration
From eye chasing objects to reaching out for touch, baby can feel exploration through eye command. With the development of eye movement, vision and the enhancement of hand eye body coordination, the baby begins to crawl and stand, and grab and throw objects independently.
Baoma Bao dad at this stage must pay attention to that indoor lighting is not easy to be too bright. It is necessary to avoid direct sunlight or light directly to the baby's eyes, not hang children's toys in a fixed position, and avoid the baby always staring at a position of the object. It can use cards or toys of various colors and materials to interact with the baby to help the baby feel the shape and texture of different items by hand, and ensure enough time for crawling and exploration, and not encourage early walking.
Over 1 year old: continuous development and Prevention
With the coordination of hand and eye and the continuous development of deep vision, it is not recommended that the baby contact any electronic screen before the age of 2. After 2 years old, the screen use time should be strictly controlled, no more than 1 hour a day, and pay attention to the 20 minutes rest for every 20 minutes of TV watching, more outdoor activities, develop good eye habits, regularly take the child for systematic ophthalmic examination, exclude amblyopia, strabismus and other conditions What's the matter.
In daily life, parents should set an example, refuse to be "screen slave", play puzzles and blocks with their children more; give children enough outdoor sports time, do more cycling, ball games, and encourage the baby to wear clothes, play rubber mud, clip stickers, etc., so as to exercise the hand eye and overall coordination ability.
After 3 years old, lutein should be supplemented in time
In addition to the observation on a regular day, pay attention to eye hygiene and ensure a good "eye" environment, parents should pay attention to eye nutrition supplement, especially lutein, a nutrient essential to the development of vision.
Lutein, also known as "eye gold", is the most important nutrient component in human retina, which is widely found in macular (visual center) and crystalline body of the retina. Lutein directly affects the therapeutic effect of myopia and amblyopia, but the human body can not synthesize lutein by itself, and can only be absorbed by the outside world.
Lutein is good, but it has some disadvantages, such as instability, easy decomposition in case of heat exposure, and small tolerance to human pH value, so it is not suitable to take orally directly and the bioavailability is low. Lutein ester can avoid these disadvantages and is more suitable for human body to take nutritional supplements. Lutein ester is a compound formed by lutein and fatty acid. It has been proved that lutein ester can be hydrolyzed into free lutein naturally in human body and improve the bioavailability of lutein crystal.
In the critical and sensitive period of children's vision development, parents must pay attention to the effective supplement of lutein, and it is better to extend to adolescence, so as to help children effectively prevent myopia.
