Abstract: human vision is gradually developed. Childhood is hyperopia. With the growth of the body, the eyeballs are also growing. The vision changes from hyperopia to emmetropia, and then to myopia. Now, because the intensity and frequency of watching mobile phones and using computers are too high and dense, and affected by environmental factors, myopia is accelerating. Once myopia occurs, as children grow up, their eyes grow up, and the degree of myopia will change., We often hear people say that children are nearsighted. Can they wear glasses or not, because they can’t take them off. The more they wear glasses, the more nearsighted they become. Will wearing glasses have a negative impact on your eyesight and lead to worse eyesight?, Then Xiaobian will take you melon eaters to solve this mystery., The cause of myopia, human vision is gradually developed. Childhood is hyperopia. With the growth of the body, the eyeballs are also growing. The vision changes from hyperopia to emmetropia, and then to myopia. Now, because the intensity and frequency of watching mobile phones and using computers are too high and dense, and affected by environmental factors, myopia is accelerating. Once myopia occurs, as children grow up, their eyes grow up, and the degree of myopia will change., Will wearing glasses damage your eyesight? The cause of myopia is clear. Let’s look at the problem of glasses. Parents think their children are short-sighted. They can’t wear glasses. The more they wear, the more short-sighted they become. This is wrong. Because: 1. Normal people’s eye imaging is on the retina. After myopia, the imaging will be in front of the retina. Wearing nearsighted glasses is equivalent to adding a concave lens to bring the image back to the retina., 2. Clinical observation shows that after myopia, the visual acuity of the naked eye cannot recover automatically. The so-called “the nearsighted you wear glasses”, you can’t take them off. It’s not the fault of glasses, but the continuous decline of vision.,

causes of myopia
human vision is gradually developed. Childhood is hyperopia. With the growth of the body, the eyeballs are also growing. The vision changes from hyperopia to emmetropia, and then to myopia. Now, because the intensity and frequency of watching mobile phones and using computers are too high and dense, and affected by environmental factors, myopia is accelerating. Once myopia occurs, as children grow up, their eyes grow up, and the degree of myopia will change.
will wearing glasses damage your eyesight? The causes of
myopia are clear. Let’s look at the problem of glasses. Parents think their children are short-sighted. They can’t wear glasses. The more they wear, the more short-sighted they become. This is wrong. Because:
1. The normal eye imaging is on the retina. After myopia, the imaging will be in front of the retina. Wearing nearsighted glasses is equivalent to adding a concave lens to make the image converge to the retina again.
2. Clinical observation shows that after myopia, the visual acuity of the naked eye cannot recover automatically. The so-called “the more myopia you wear glasses”, you can’t take them off. It’s not the fault of glasses, but the continuous decline of vision.
therefore, if the glasses are accurate, wearing glasses will not aggravate the degree. Not wearing it will aggravate the degree of myopia.
scientific prevention and control of myopia
optometry experts suggest that we must grasp the root of scientific prevention and control of myopia. Mastering three secrets can help parents scientifically guide their children to prevent and control myopia. Tips of
and
1. Reduce close eye use: formulate a reasonable learning plan for children, reduce close reading and writing, and take a break and look into the distance for 10 minutes every 40 minutes of continuous close reading.
secret 2. Sufficient outdoor activities: more and more studies and evidence show that outdoor activities can effectively control the occurrence and development of myopia. The mechanism is that outdoor high illumination can promote the secretion of dopamine and dopamine can inhibit the growth of ocular axis. Therefore, it is recommended that children carry out outdoor activities for 2 hours every day. They should go to outdoor activities during recess instead of staying in the classroom. Secret of
and
3. Establish refractive development files: children need to go to professional education when they are three years old Regular ophthalmic service institutions establish refractive development files (regularly check corneal curvature, eye axis, ciliary muscle paralysis and pupillary optometry results, intraocular pressure, height and other indicators), and ask professional optometrists to analyze and evaluate various parameters of children’s eyes and formulate scientific intervention plans for you.
Optometrists suggest that if your child has myopia or does not have myopia, you need to form the habit of going to a regular eye service institution for comprehensive optometry examination; Establish refractive development files, monitor children’s visual changes and intervene in time!
