It is estimated that half of the world’s population will be short-sighted by 2050. Don’t you cherish your eyes?

Abstract: why is the number of myopia so large? This is undoubtedly inseparable from the change of people’s living habits. Due to the rapid development of information and transportation, people spend less and less time outdoors. On the contrary, they spend more and more time staring at the screen or books. Experts explained that the occurrence and development of myopia are closely related to close work., In recent years, myopia has become a major problem perplexing global vision health. Recently, Australian researchers estimated that in 2000, about 1.4 billion people in the world were short-sighted, accounting for 22.9% of the world’s total population, of which 163 million were in serious condition. At present, among the 7.3 billion people in the world, there are about 2 billion people with myopia. It is estimated that by 2050, the number of myopia will reach 4.758 billion, accounting for 49.8% of the global population, of which 938 million will be in serious condition., This is a serious trend because deep myopia means a greater risk of eye conditions, such as myopic maculopathy, cataract, glaucoma and retinal detachment. These conditions can lead to permanent blindness., Why is the number of myopia so large? This is undoubtedly inseparable from the change of people’s living habits. Due to the rapid development of information and transportation, people spend less and less time outdoors. On the contrary, they spend more and more time staring at the screen or books. Experts explained that the occurrence and development of myopia are closely related to close work. The eyeballs of teenagers, in particular, are in the stage of growth and development, with strong adjustment ability and large extension of the ball wall. The adjustment and collection function of reading and other close work makes the internal rectus muscle exert certain pressure on the eyeballs, and the intraocular pressure increases accordingly. With the continuous increase of work, the frequency and time of adjustment and collection also gradually increase, Ciliary muscles and extraocular muscles are often in a state of high tension. Excessive regulation can cause ciliary muscle spasm, resulting in temporary vision loss., How to protect eyes and prevent myopia?, 1. Keep a good working posture, keep the most appropriate posture, and make your eyes look flat or look down slightly on the fluorescent screen, so as to relax the neck muscles and minimize the area of eyeballs exposed to the air., Do not turn your eyes.

Recently, Australian researchers estimated that in 2000, about 1.4 billion people in the world were short-sighted, accounting for 22.9% of the world’s total population, of which 163 million were in serious condition.

It is estimated that by 2050, the number of myopia will reach 4.758 billion, accounting for 49.8% of the global population, of which 938 million will be in serious condition.

this is a serious trend, because deep myopia means a greater risk of eye conditions, such as myopic maculopathy, cataract, glaucoma and retinal detachment. These conditions can lead to permanent blindness.

how to protect eyes and prevent myopia?

1 maintain a good working posture

maintain the most appropriate posture to make both eyes look down or slightly look down at the fluorescent screen, which can relax the neck muscles and minimize the area of eyeballs exposed to the air.

2 never turn your eyes.

pay attention to frequent and complete blinking. Frequent blinking can reduce the time of eye exposure to the air and avoid the evaporation of tears.

3 the air conditioner

should not be blown for too long to avoid airflow on the seat, and tea should be placed near the seat to increase the surrounding humidity.

4 avoid continuous operation of the computer for a long time.

pay attention to rest in the middle. Usually operate continuously for 1 hour and rest for 5-10 minutes. At rest, you can look far away or do eye exercises.

5 adjust the distance between the fluorescent screen and the position

. The recommended distance is 50-70cm, and the fluorescent screen should be 10-20cm lower than the horizontal position of the eye, with a downward viewing angle of 15-20 degrees. Because the angle and distance can reduce the demand for refraction and reduce the probability of eye fatigue.

6 eat more fruits

, especially citrus fruits. You should also eat more green vegetables, grain, fish and eggs. Drinking plenty of water can also help reduce dry eyes.

7 maintain good living habits

ensure adequate sleep and do not stay up late.
