Contemporary society, young people not only often back pain, excessive use of eyes also abound, suffering from vision problems are more and more people. So when people do sports to exercise the body, have you ever thought that the eyes can also exercise?
Why is it that the eyes can do exercise?
The eye is like a camera, the lens is the focus of our eyes, and drive the lens focus movement is the ciliary muscle. The ciliary muscle is like the muscles of our arms and legs, play a regulatory role in the movement, when our muscles work for a long time, or a long time in a state of work, fatigue symptoms will occur.
For example, if you sit down every day, after 3 hours, you will feel lumbar pain and back pain, which is the fatigue of your lumbar and back muscles. Similarly, using a computer for 3 hours, your eyes will be tired, we call it visual fatigue, that is, the ciliary muscle fatigue of our eyes focusing movement, it can not produce effective movement, the eyes can not focus.
Life, in order to see the near target needs through the eye ciliary muscle contraction, to make the eye lens curvature increased, thus enhancing the refractive power of the eye, so that the near object retina to form a clear image. This function of changing the refractive power of the eye in order to see close objects is called ocular accommodation.
Then the eyes do exercise, that is to say, to do visual training, can regulate the abnormalities of our eyes, to relieve the pressure and fatigue of the ciliary muscle, just as exercise exercise human muscle, visual training can exercise the ciliary muscle regulation ability.
Why do you need to do exercise for your eyes?
01. Visual training can control the growth of myopia
Visual training is a common training for children with binocular vision dysfunction, which aims to increase the magnitude of the child's eye adjustments, strengthen their adjustments, and eliminate the effects of the dysfunctions on myopia.
Therefore, visual training has a certain control effect on the growth of myopia, although it can't guarantee no length count, but it can slow down the growth of myopia.
02. Visual training can eliminate eye fatigue
Visual fatigue is caused by fatigue of the ciliary muscle of the eye responsible for adjustment, or the eye is in a state for a long time, causing the lens can not focus quickly. As focusing is driven by ciliary muscle muscle movement, muscle strength, speed, amplitude can be exercised.
Therefore, we can effectively train the ciliary muscle through visual training, change its working condition, increase its muscle strength and movement speed, amplitude, improve the eye focusing ability, so that the eyes are not easy to fatigue.
03. Visual training can prevent myopia
Visual training is a set of eye training methods based on the specific eye condition of the trainee. Visual training can significantly improve pseudomyopia and control the progression of myopia in adolescents, and is effective in improving visual acuity, enhancing visual skills, developing visual potential, and improving visual function.
Visual training programs vary from person to person and are designed to promote eye movement and enhance eye regulation, thereby preventing myopia.
How do I do exercises for my eyes?
Depending on the method of training and the training tools involved, training can be categorized into home training methods and professional training methods. Home training can be done at home, through small games or interaction, under the care of parents, training operation is simple and widely applicable.
Specialized training must be carried out under the guidance of a professional trainer, and is more targeted to children who are nearsighted or amblyopic, or who have chronic visual fatigue. Visual training is accomplished through instrumental training and interaction with the trainer. At the same time, it is necessary to adjust the training methods and programs at different stages according to the training experience.
Here are a few tips for parents:
1. Passing and catching the ball: Parents can pass the ball around the house with their children, encouraging them to participate fully. You can also take your child to play table tennis, badminton, etc., mainly to exercise the child's hand-eye coordination and visual tracking ability.
2. Pick beans: you can put soybean green beans and other beans of similar size on the plate, let the child hands to sift them out. The main exercise is to exercise the child's visual response and hand fine motor, but also can develop the child's concentration.
3. Trouble-shooting: Let your child focus on two different things and let him tell the difference between them.
