According to statistics, China's nearsighted population accounts for 30% of the total population, and the urban nearsighted population accounts for 33%. Among them, the proportion of primary school students wearing glasses is 30%, middle school students are 50% and college students are 75%. Ranked second in the world. Statistics show that the incidence of myopia in China has reached 3. 600 million, the first in the world.
In this regard, I would like to make the following suggestions:
First, the light must be sufficient: the light should be sufficient and comfortable. If the light is too weak to see the font clearly, it will get closer and closer.
Second, reflection should be avoided: there should be a lighting device next to the desk, in order to reduce reflection and reduce the damage to the eyes.
Third, the reading time should not be too long: whether doing homework or watching TV, the time should not be too long, and it is best to take a break every 30 minutes.
Fourth, the sitting posture should be correct: don't stoop. The closer you get to doing homework or squatting, it will easily cause excessive tension in the ciliary muscles, leading to myopia.
5. The reading distance should be moderate: the distance between books and eyes should be 30 cm, and the height of tables and chairs should also match the physique.
6. Don't watch TV too close: When watching TV, keep the diagonal distance of the TV screen six to eight times, and have a rest every 30 minutes.
Seven, sleep can not be too little, regular work and rest: lack of sleep is easy to fatigue, easy to cause false myopia.
Eight, do more outdoor sports: often overlooking can relax eye muscles, prevent myopia, and get in touch with the green mountains and green waters in nature, which is conducive to eye health.
Nine, nutrient intake should be balanced: not partial eclipse, should pay special attention to the intake of vitamin B (germ rice, cereal yeast).
X. Routine eyesight: Anyone with abnormal eyesight should go to a qualified eyewear company or ophthalmologist for further examination.
The eyes are the windows of the soul, but they are the windows for us to appreciate this beautiful world. Take good care of your eyes and treat every day with your eyes as the day before you will lose your light.
Protecting your eyes is everyone's responsibility.
