In a relaxed state, the parallel light passes through the refractive system of the eyeball and focuses in front of the retina, which is called myopia. Myopia is also called shortsightedness, because this kind of eye can only see near but not far. When the eye is resting, the parallel light from the infinite distance, after passing through the refraction system of the eye, gathers in front of the retina to form a focus, and forms an unclear image on the retina. The far vision is obviously reduced, but the near vision is still normal. There are many factors that cause myopia, one is genetic factor, the other is acquired external factor. Here we mainly explain the way to alleviate myopia caused by acquired factors.
(1) Relax:
① Mydriasis therapy: mydriasis with cycloplegia is used. At present, eye drops are given once a day.
2. Convex lens method: first let the patient wear a convex lens with a higher degree, watch the vision meter 5 meters away, relax the ciliary muscle, then adjust the degree of the convex lens, so that the eyesight is basically normal.
③ Overlooking method: after studying or writing for 1-2 hours, you can overlook the natural scenery and relax the ciliary muscles. Keep on doing eye exercises 3-4 times a day.
(2) To improve the excitability and visual function of the visual center:
Direct current therapy for myopia, ear acupuncture, plum blossom acupuncture, acupoint massage, acupoint conduction, Qigong therapy and cold water bath therapy. It is mainly to increase the excitability of the brain's optic center and optic nerve cells, which can improve both the near and far vision.
(3) Improve learning environment: keep a distance of 30cm and correct posture when reading and writing. Pay attention to the natural light and ensure adequate lighting in the room. Combine work with rest, get rid of bad study habits, take a rest of 10-15 minutes every hour, do not lie or walk to read. Pay attention to physical exercise
Of course, there are many specific methods, such as:
1: Stand somewhere, find a distant tree and a closer tree, and then observe the trees near for a while, and then observe the trees far away for a while. This method has the function of adjusting eye muscles and relaxing. When observing, try to look at the details of the tree as much as possible
2: Rub your hands and cover your eyes. Do it again and again. It's relaxing and comfortable. You can do it anytime, anywhere.
3: Sunbathe, when the weather is clear, close your eyes, face the sun, let the light through the eyelids, stimulate the eye cells. Our nearsighted people are very sensitive to light. They will squint or squint when they encounter strong light. This can improve the ability of our eyes to accept light.
4: Sit or stand, look straight ahead first, then move your eyes up, down, left and right, and stretch your eyes in each direction as much as you can, just for a few seconds in each direction. We will find that our eyes are deformed after myopia. This method can adjust our eyes back to normal shape and help to restore the focusing ability of the eyes.
5: More blinking, blinking can alleviate eye fatigue, this is to do at any time.
According to the above methods, combined with reasonable vision correction, I believe that you will feel that your eyesight has indeed improved after a period of time. My friends have tried it for a month, and the eyesight has dropped from the original 400 to 300 degrees. He is still insisting. Listening to him, the effect is very good. You may as well try it.
