Abstract: myopia (axial myopia) is caused by the lengthening of the eye axis. The light entering the eyeball cannot focus on the retina, but falls in front of the retina. Therefore, it is necessary to wear a concave lens to move the focus backward. The longer the eyeball, the higher the degree of concave lens required, that is, the higher the degree of myopia.
Now, more and more children wear thick glasses at a young age. As parents, the most anxious thing is to watch their children’s myopia soar every year. In particular, parents with myopia are more reluctant to watch their children’s life and study because of vision problems.
have too many methods to prevent and control myopia: acupuncture, blinking, electronic massage… People have no choice. Parents are always looking for whether there is a feasible method without risk? Why should
be prevented? Because myopia is irreversible!
myopia (axial myopia) is caused by the lengthening of the eye axis. The light entering the eyeball cannot focus on the retina, but falls in front of the retina. Therefore, it is necessary to wear a concave lens to move the focus backward. The longer the eyeball, the higher the degree of concave lens required, that is, the higher the degree of myopia.
In other words, myopia is caused by the lengthening of the eyeball. Therefore, parents should recognize a reality: the degree of axial myopia will basically only deepen, not decrease. This is why the prevention of myopia has been emphasized.
moderate outdoor exercise every day is the best means of prevention.
teenagers and children are in the period of growth and development. Like physical development, the development of vision also has its own process, which is generally stable around the age of 18. Due to academic pressure, Every day, children have to use their eyes closely for a long time (reading and doing questions), and their eyes are prone to fatigue. If they use electronic products at other times, they may have long-term spasm of ciliary muscles, elongated eye axis and myopia.
In a study, children in six schools began to increase 40 minutes of outdoor courses every day from the age of six or seven. After three years, the myopia rate was 30%, while the myopia rate of children in the control group was 40%.
therefore, in spare time, it is recommended to ensure that children stay away from electronic products and take adequate outdoor sports every day, so as to relax their eyes. This is also recognized as the most effective, harmless and economical method for the prevention and treatment of myopia.
