More than half of children and adolescents in my country suffer from myopia

  To pay attention to visual health, we must first understand what is impaired vision?

  Feng Shi, a postdoctoral doctor in the Department of Ophthalmology at Peking Union Medical College Hospital, said that visual impairment refers to long-term blurred vision of distant or near objects, which can be divided into four types: blindness, moderate to severe, mild, and near vision impairment.

  The World Health Organization's first "World Sight Report" released in 2019 shows that at least 2.2 billion people worldwide are visually impaired or blind, of which at least 1 billion people have visual impairment that could have been prevented or has yet to be resolved.

  According to a press conference held by the National Health Commission in July this year, the overall myopia rate of children and adolescents in my country in 2020 is 52.7%, and the problem of myopia and aging of children in my country is still prominent.

  In addition, monitoring in 2020 shows that about 10% of myopia students have high myopia, and kindergartens and elementary schools are the key ages for myopia prevention and control in my country.

  Experts say that high myopia is prone to cause a variety of serious complications, such as cataracts, retinal detachment and glaucoma, which are blinding eye diseases that are focused on prevention and treatment.

Why are there more and more "small glasses"?

  Nowadays, children with glasses can be seen everywhere. Why are there more and more people with myopia, and their age is getting younger and younger?

  Jiao Yahui, director of the Medical Administration and Hospital Administration of the National Health Commission, once said that besides genetic factors, myopia also has some incorrect eye habits, such as incorrect reading and writing posture of children, and reduced outdoor activities.

  In addition, you can often see in public places that, in order to prevent children from crying, parents, especially young parents, show their children their mobile phones or tablets to watch videos and play games.

  These electronic products are enriching their spare time and facilitating their lives. At the same time, they do bring a great threat to children's vision problems.

  Experts say that myopia not only brings inconvenience to our study, work, and life, but serious myopia can also bring some complications, and it is also one of the factors that cause blindness.

Expert: 90% of vision problems can be prevented and cured

  Han Ruoan, the attending physician of the Department of Ophthalmology at Peking Union Medical College Hospital, said that 90% of vision problems are preventable and treatable.

For example, cataract is the most important cause of blindness. About 100 million people suffer from cataracts that have impaired vision. Cataract surgery can help these patients restore their vision.

  Uncorrected refractive error is the primary cause of vision loss. These patients can restore their vision by wearing appropriate glasses, contact lenses, or undergoing refractive surgery.

  So, how to prevent vision loss, protect, maintain and optimize vision?

  Feng Shi said that a healthy lifestyle can prevent many eye diseases.

In the diet, intake of vitamin A, vitamin C, vitamin E, omega-3 fatty acids, lutein, zinc, etc. can nourish the cornea, retina, and delay the progression of diseases such as cataracts and age-related macular degeneration.

  Han Ruoan introduced that he also protects his eyes in the following simple ways:

  Wear protective goggles.

When doing work or activities that may cause eye injury, be sure to wear goggles to prevent damage to your eyes from ultraviolet rays, high temperatures, chemical or radioactive materials, and splash particles.

  Pay attention to timely cleansing eye makeup.

Residual cosmetics may cause eye allergies, dry eye surface, etc.

  Reduce the time of using electronic equipment.

Take moderate rest and avoid staring at the screen for long periods of time.

Follow the "20-20-20" principle: After working for 20 minutes, look at an object 20 feet (about 6 meters) away and let your eyes rest for 20 seconds.

  In addition, experts advocate regular systematic eye examinations to check vision, intraocular pressure, and dilate pupils if necessary, to assess eye health, early detection of some hidden eye diseases, maintain existing vision, and avoid vision loss.
