How to prevent the children from suffering from myopia has always been a topic that most of the parents care about. Apart from having a balanced diet, not writing or reading in the sunshine, not using the eyes for a long time, etc., do you know enjoying sunshine is also very helpful for preventing the children’s myopia? As for the reasons, I think they can be listed as below:
First of all, enjoying sunshine can accelerate the exudation of vitamin D that can increase the absorption of calcium by the children’s body. Calcium is an indispensable element for the human body, therefore, for eyes, lack of calcium is likely to weaken the elasticity and surface tension of the wall of eyeball. The children’s ocular axis is easy to be lengthened when they do some near-distance work or lower their heads, so that the myopia occurs and develops.
Second, enjoying sunshine can promote the children’s bodies to exude more dopamine which can effectively stunt the growth of eyeball so as to impede the occurrence and development of myopia.
Third, sunshine can make the children’s pupils contracted and increase the focusing force of their eyes to see more clearly, hence preventing their eyes from suffering myopias.
Fourth, as people usually enjoy the sunshine outdoors, when the sunlight is strong they seldom see near objects; on the contrary, they will see far and do some sports instead in order to relax their eyeballs. This is just the best way to protect their eyesight and it is also conducive to preventing myopia.
It is worth to be mentioned that we should let our children do more outdoor activities and enjoy as much sunshine as possible, allowing the UV ray from the sun to directly shine on the children for over 2 hours everyday to enable them to get sufficient dopamine and vitamin D. It is true that the children living in today’s world are busy with study, but anyhow the parents should take them to do sports and play outdoors as far as possible.
