Abstract: if you suffer from myopia, don’t blindly go to the glasses store for computer optometry. It must be noted that students under the age of 12 should use 5% tropicamide eye drops to dilate their pupils and optometry after the ciliary muscle is relaxed, so as to eliminate the possibility of false myopia and avoid unnecessary optometry., Myopia refers to that when the eye is in a regulated state, the parallel light passes through the refractive system of the eye and forms a focus in front of the retina, so it is blurred to see far. Generally, the front and rear eye axes of teenagers with myopia are longer than those of normal teenagers, so the focus of light falls in front of the retina. It is necessary to wear a concave lens in front of your eyes to divergent light, so that the focus just falls on the retina, that is, to form a clear image., To distinguish between true myopia and false myopia: if you suffer from myopia, don’t blindly go to the glasses store for computer optometry. You must pay attention to that students under the age of 12 should use 5% tropicamide eye drops to dilate their pupils and perform optometry after the ciliary muscle is relaxed, so as to eliminate the possibility of false myopia and avoid unnecessary optometry., (1) pseudomyopia is caused by excessive use of the eyes at close range. The focus of the ciliary muscle in the eye is moved closer through contraction adjustment. Over time, it shows temporary myopia. After using pupil dilators, the ciliary muscle is relaxed and the myopia can disappear (2) True myopia is due to heredity or overdevelopment, which makes the eye axis elongate. After using mydriasis drugs, the myopia phenomenon has not changed. If it is false myopia, there is no need to wear glasses, and the symptoms will be reduced after eye rest and relaxation. True myopia needs to wear glasses. Glasses principle: choose the lens with the lowest degree to enable the patient to obtain the best vision. How to prevent false myopia Become true myopia?, 1. Balanced nutrition, supplemented with chromium and zinc.
myopia refers to that when the eye is in a regulated state, the parallel light forms a focus in front of the retina after passing through the refractive system of the eye, so the vision is blurred. Generally, the front and rear eye axes of teenagers with myopia are longer than those of normal teenagers, so the focus of light falls in front of the retina. It is necessary to wear a concave lens in front of your eyes to divergent light, so that the focus just falls on the retina, that is, to form a clear image.
and
should be divided into true myopia and false myopia:
and
suffer from myopia. Do not blindly go to the optical shop for computer optometry before fitting glasses. It must be noted that students under the age of 12 should use 5% tropicamide eye drops to dilate their pupils and optometry after the ciliary muscle is relaxed, so as to eliminate the possibility of false myopia and avoid unnecessary glasses.
(1) pseudomyopia is caused by excessive use of the eyes at close range. The focus of the ciliary muscle in the eye is moved closer through contraction adjustment. Over time, it shows temporary myopia. After using pupil dilators, the ciliary muscle is relaxed and the myopia can be eliminated.
(2) True myopia is caused by heredity or overdevelopment, which makes the eye axis elongate. After using mydriasis drugs, the myopia phenomenon remains unchanged.
if it is false myopia, there is no need to wear glasses, and the symptoms will be reduced after eye rest and relaxation. True myopia needs to wear glasses. Glasses principle: select the lens with the lowest degree to enable the patient to obtain the best vision.
How to prevent false myopia from becoming true myopia?
1. Nutrition is balanced and chromium and zinc are supplemented. Friends with pseudomyopia should eat more foods containing more zinc. Foods such as soybeans, almonds, laver, kelp, mutton, yellow croaker, milk powder, tea, meat, beef and liver contain more zinc and chromium, which can be increased appropriately.
2. How to eliminate pseudomyopia and improve the learning environment
reading and writing should keep a distance of 30 cm at any time and have a correct posture. Pay attention to natural light and ensure adequate indoor lighting. Combine work and rest, get rid of bad learning habits, and rest for 8 ~ 10 minutes every half an hour.
3. Stimulate the visual center and improve visual function.
DC treatment of myopia, ear acupuncture, plum blossom acupuncture, empty massage, acupoint conduction, Qigong therapy and cold water bath therapy. It mainly increases the excitability of the visual center and optic nerve cells of the brain, which can improve the far and near vision. (you should go to a regular eye hospital for treatment)
4. Relax and adjust
① mydriasis therapy. Apply cycloplegic agent to mydriasis. You can use eye drops once a day.
② wearing convex lens method. First, let the patient wear a convex lens with a higher degree, watch the vision meter at 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, overlook the natural scenery to relax the ciliary muscles.
