Knowledge of myopia prevention and control

In 2020, the overall myopia rate among children and adolescents in China was 52.7%, with a myopia rate of 14.3% for 6-year-old children, 35.6% for primary school students, 71.1% for junior high school students, and 80.5% for high school students. These data all show the serious situation of myopia in Chinese children

Therefore, for domestic children, the incidence rate of myopia has become a serious problem

1. Cultivate good eye habits

The correct sitting and reading posture can effectively reduce the burden on the eyes. Maintain a distance between your gaze and the book or screen, and avoid looking down or using your eyes at close range for extended periods of time. At the same time, it is important to control eye usage time, allowing the eyes to rest at regular intervals and performing appropriate eye exercises to alleviate eye fatigue

2. Create a good eye environment

The eye environment is crucial for visual health. Study or read in a well lit environment and avoid using your eyes in dim or bright light. In addition, it is advisable to minimize prolonged use of electronic devices such as televisions, computers, etc. to reduce eye irritation

3. Increase outdoor activity time

Engaging in at least two hours of outdoor activities every day can help prevent myopia. Outdoor activities can allow children to bask in natural light, which helps alleviate eye fatigue and has a positive effect on preventing myopia

4. Pay attention to nutrition

A reasonable diet is crucial for children's visual health. Eat more vegetables and fruits rich in vitamins and minerals, such as carrots, tomatoes, oranges, etc. These foods help protect the eyes and prevent the occurrence of myopia

5. Regular vision check ups

Regular vision check ups are an important step in preventing myopia. If vision loss or myopia symptoms are found, it is necessary to go to the hospital for examination in a timely manner and take corresponding prevention and control measures according to the doctor's advice

In short, protecting children's visual health requires parents' attention and active action. By cultivating good eye habits, creating a good eye environment, increasing outdoor activity time, paying attention to nutrition, and regularly undergoing vision checks, we can effectively prevent the occurrence of myopia and safeguard children's future

If a child is already nearsighted, not only should they achieve the above points, but they also need to actively correct and control their myopia

There are currently several mainstream methods for correcting and controlling myopia:

1. Corneal reshaping lens: It is a specially designed rigid high oxygen permeability contact lens that is worn during sleep every night, and can be removed after waking up during the day to obtain clear naked eye vision. It can also effectively slow down the development of myopia. Suitable for children over 8 years old who do not want to wear glasses

2. Defocused frame glasses: A frame lens designed based on the principle of peripheral myopia defocusing. Wearing this lens can not only correct myopia, but also effectively slow down the development of myopia, suitable for children of any age. At the same time, defocused frame glasses also have some advantages, such as special lens material, thinner and lighter, UV protection, and good impact resistance

3. Defocusing soft lenses are a type of soft contact lens with defocusing function, worn during the day and removed at night, which can correct myopia and prevent its progression. Suitable for children who enjoy sports but do not like wearing glasses

4. Low concentration atropine: Low concentration atropine is a medication that can be used to control the development of myopia, but it cannot correct myopia. To correct myopia, it is necessary to wear frame glasses. It can also be combined with OK glasses, defocused frame glasses, or defocused soft glasses to enhance the effect of myopia prevention and control

The above are the current mainstream methods for correcting and controlling myopia. Parents need to choose and use them under the advice and guidance of doctors
