Children with high myopia, in middle and old age, the risk of blindness is much higher than the normal population. In developed countries, high myopia has become the number one cause of blindness and visual impairment. Myopia is not only a problem of wearing glasses, but also related to the future health of teenagers, especially visual health.

The myopia rate of children and adolescents is increasing year by year and tends to be younger. The problem of "small glasses" is very prominent. How should parents protect their children's eyes and let them have a bright future?

The incidence of myopia has several important characteristics: the first is a high incidence, the second is a young age, and the third is a high proportion of high myopia.

At present, more than 10% of children in kindergarten are nearsighted. This obviously young age is very scary. Among high school students, high myopia has exceeded 20%, while 20 years ago, the proportion of high myopia was only about 2% to 5%.

A large number of facts have proved that the gradual increase of after-school tutoring has consumed a lot of time and energy for children, and most children have not only failed to improve their academic performance, but their eyesight has significantly decreased.

The eyesight health of young people is related to the future of our country.

Children should reduce the homework burden, reduce the close eye time, and increase the time for outdoor activities.

Prevent children myopia, parents are duty-bound, how to protect children's eye health in daily life?

First of all, parents need to know the condition of their children's eyes. No matter how old the child is, from birth, kindergarten, primary school, middle school, parents must grasp the basic data of the child's eyes in time, and must go to the hospital to dilate, optometry, check vision and measure the axis of the eye.

If the child is 6 years old and 200 degrees of hyperopia, it means that the hyperopia reserve is good, and then through good control, it is not easy to myopia.

Secondly, urge children to develop good eye habits. Studies have found that children play mobile phones for 20 minutes, the average eyesight dropped to 43.8 degrees of myopia; Playing iPad continuously for 20 minutes, the average vision dropped to 41.7 degrees of myopia; After watching LCD TV for 20 minutes, the average eyesight dropped to 18.8 degrees of myopia.

The variety of colors and rapid changes of the electronic product screen require the pupil to adapt to different intensity light in a short time, which can easily lead to or aggravate myopia.

And when children are playing mobile phones or watching TV, their eyes stare at the screen for a long time, which is easy to cause eye fatigue.

Children should not use electronic devices for too long, to remember the "202020" mantra: 20 minutes of electronic devices, to look 20 feet (6 meters) away, at least 20 seconds.

But it does not mean that children can free themselves, children at home, parents should be more strict control of children's use of electronic products time, a continuous use should not exceed half an hour; When you must use electronic tools, try to choose a large screen, high resolution electronic products, the order of selection is projector, TV, computer, tablet, mobile phone, screen font should also be as large as possible, the background picture color is not too light.

Third, take your children to do outdoor activities for at least 2 hours a day.

Do not make up lessons, parents should take their children to participate in outdoor activities, more contact with nature, so that children's eyes can fully relax.

At least 2 hours of outdoor activities a day, both can strengthen the body, but also can prevent myopia.

Sunlight can stimulate the retina to produce more active substance dopamine, dopamine can promote the normal development of the eyeball, inhibit the growth of the eye axis, can prevent or delay the development of myopia.

An Australian study found that children spend 1 hour a day outdoors, the myopia rate is about 3%; When outdoor activities reach 3 hours a day, the myopia rate is only 0.8%.

Fourth, monitor your child's vision regularly.

Every semester, regardless of whether the child is nearsighted, at the end of the semester, parents should take their children to optometry, look at vision, and look at eye conditions.

If you already have myopia, it is more necessary to go to optometry to see changes in vision.

Parents should take their children to do vision tests every semester to understand whether the child's eye development is normal and whether there is a risk of myopia; If the child is already myopic, try to prevent the child from becoming highly myopic.

Fifth, ensure that children eat a reasonable diet and get enough sleep.

Balanced diet and reasonable collocation help children's eye development, parents should supplement more fresh food rich in DHA, lutein, anthocyanin, beta-carotene for children. At the same time, ensure that the child gets enough sleep, and ensure the quality of sleep, so that the child's eyes get enough rest.

When children read at home, they must have a reading environment suitable for light, maintain a good healthy reading posture for children, and reasonably arrange reading and rest time.

It is important for parents to lead by example.

Many parents tell their children not to play with mobile phones, but themselves play endlessly; There are parents who use the iPad as a toy, babies and even babies cry, they use the iPad to coax their children, in fact, the earlier the child uses electronic products, the greater the visual damage, the more chance of myopia.

Give children and teenagers a myopia prevention and control key: "tree foresight, myopia prevention, less video, more exercise, not picky food, sleep, pro-nature, heart window." To prevent and control myopia in children and adolescents, schools, families and society need to work together to protect children's bright future.
