Can outdoor exercise make vision better, and can outdoor exercise prevent myopia

Yes. More and more scientific studies have shown that 2 hours of outdoor activities a day can effectively prevent the occurrence and progression of myopia, and is currently the most cost-effective myopia prevention and control measure.

Outdoor exercise can prevent myopia is a conclusion based on the observation of a large number of clinical data in recent years, and its principle is mainly the following aspects:

1.When exercising outdoors, the eyes usually focus on distant objects, so that the ciliary muscles are relaxed and the eyes are rested, which can play a role in preventing myopia.

2.When exercising outdoors, the probability of changing the eyes from far to near will be relatively large, so that the adjustment function of the ciliary muscle has been exercised, which is also effective in alleviating visual fatigue and eliminating pseudomyopia.

3.Exposure to sunlight during outdoor exercise can help calcium absorption, and calcium supplementation can increase the strength of the sclera and delay the formation of axial myopia.

Professor Kathryn Rose pointed out that based on the results of previous cross-cutting studies, about 2 hours of outdoor activity per day can have the effect of reducing the risk of myopia.

Life is difficult to have smooth sailing, but whether it is for ourselves, for our families, or for our dreams, we can't stop working hard. May in the new year, all sweat will be harvested, and all efforts will not be disappointed.

No! I firmly believe that there must be a harvest for paying, there must be a fruit for sowing, people are good or bad for this harvest, more and less, the size of the fruit is another thing, and then think about it, I feel nothing! The quality of the harvest, the size of the fruit, this kind of power still belongs to us, "do my best", as long as you have worked hard, why care about the result?

As long as you have it, why care about the good or the bad? Only if you have done your best, why should you pay attention to the amount of gain?

Harvest, in the fall. Joy spreads in the fiber-filled air. People reaped the fruits and laughter, and a happy atmosphere filled the surroundings. Sowing in the spring, ploughing in the summer, and reaping in the autumn seems to be an eternal truth.

October is the harvest season, and the beautiful northern country is even more picturesque: you look at the endless rice fields, the rice waves are rolling, a golden yellow, like a golden ocean.

If you understand me, your affection is long, your heart is full of joy, and you can go all the way, and you will be smooth. Love**, flowers**, harvest**. Dipped in warmth, the water waves are stirred, and a pair of shadows are reflected. Inspiration came suddenly, and there was a beautiful article, which was refreshing and refreshing.

Those who only fantasize and do not act will never experience the joy of reaping the fruits.

Giving may not necessarily be rewarded; If you don't give, you won't get anything, and don't expect miracles.

In the eyes of a farmer, receiving golden fruits in autumn is success, harvest; In a student's view, making progress in learning and getting good grades is success and harvest; In a worker's view, producing better and more products is success and harvest; In a chef's opinion, making a beautiful and delicious dish is success and harvest.

We have a natural inertia, always thinking about suffering the least, taking the shortest detours, and getting the greatest benefits. There are some things that others can do for you, but they can't feel for you, and without this mental journey, even if you succeed, the spiritual field is still a barren. The happiness of success and the satisfaction of harvest are not at the end of the struggle, but in the process of struggle, the road you should take must be walked by yourself, and others cannot replace it.

Because it has less radiation to the eyes, it will not lead to overuse of the eyes, which is conducive to eye relaxation. Spending more time in nature is not only good for your eyes, but also good for your physical and mental health.

Because the outdoors is natural light, the natural environment is good for people's eyes and body. On the other hand, there are three-dimensional reasons for this. The outdoor environment itself is three-dimensional, coupled with the sunlight and light and dark shadows, so that the vision will have a strong sense of hierarchy.

When children are running and jumping, the eyes and three-dimensional objects form a relative motion relationship, which will be very beneficial to the health of the eyes.

Children are little angels in nature, and it is their nature to love outdoor activities. But what children lack most nowadays is outdoor activities, mobile phones, tablets are inseparable from the hands of every child, and there is endless homework.

In this way, long-term eye use is the most important cause of acquired myopia, so physical exercise and outdoor activities are one of the best measures to prevent myopia. Prolonged close-up use of the eyes will cause the ciliary muscles to be in a state of spasm, so students should not stay in the classroom during recess, but should go to the open environment outside to broaden their horizons and relax their adjustments, which will help eliminate eye fatigue.

Doing more outdoor activities is a good way to see more far and near. Outdoor activities can receive sunlight to meet the needs of the eyes for sunlight in an open environment, greatly relax the eye adjustment, reduce the forced elongation of the eye axis, maintain normal visual function, and reduce the incidence of myopia. Let your child play under the blue sky and white clouds, with a pair of bright and clear eyes!

1. Small ball movement.

An important cause of myopia is excessive eye fatigue. For people who have been working in close proximity for a long time, the lens is always in a state of height adjustment, which causes visual fatigue. At the same time, when looking at a near object, the two eyeballs converge in the direction of the root of the nose, causing the extraocular muscles to compress the eyeballs, and over time, the eye axis will slowly become longer, forming myopia.

When playing table tennis, badminton and other small balls, the eyes aim at the ball, and constantly adjust the movement up and down to relax and contract, which can improve the tension of the ciliary muscle; The extraocular muscles can also be constantly active, promote blood circulation in the eye tissue, improve eye vision, and eliminate eye fatigue.

2. Mountaineering and hiking.

Climbing is a sport that benefits the whole body and mind, including the eyes. In the mountains, especially at the top of the mountain, you can extend your vision into the distance, naturally adjust your eye muscles, and help your eyes relax and rest. It also increases the time spent in the sun, which prompts the body to synthesize more vitamin D, which can increase the body's calcium absorption.

For the eyes, calcium deficiency is easy to weaken the elasticity and surface tension of the eye wall, and it is easy to elongate the eye axis and develop myopia when using the eye at close range or in the state of bowing the head. Exposure to the sun can also make the pupils constrict, increase the focus of the eyes, and see things more clearly, thereby relieving visual fatigue and improving vision.

3. Bounce on the spot.

When jumping, all organs of the body enter a state of movement. Several eye muscles in the eye work together to make the image appear clearly on the retina, so as to ensure the balance of the body when falling. Ordinary exercises, such as running and swimming, have limited coordination exercises for eye muscles, while bouncing can make the retina carry out sharp imaging activities that are difficult to carry out in ordinary times, so that the vision can be adjusted, and it invisibly plays a role in eye care.
