Definition and harm of myopia

Myopia refers to that when the human eye looks at an object from a long distance, the light cannot be fully focused on the retina due to the long axis of the eye or the abnormal diopter, resulting in the blurred object from a long distance. The harm of myopia is mainly reflected in the following aspects:

1. Impact on learning: myopia reduces children's vision and prevents them from clearly seeing the content on the blackboard, which affects the learning effect.

2. Increase eye fatigue: staring at books or electronic devices for a long time is likely to cause eye fatigue and dryness.

3. Increased risk of eye disease: myopia will increase the risk of eye disease, such as retinal detachment, cataract, etc.

Scientific eye use, correct eye posture

The correct eye posture includes the following aspects:

1. Keep an appropriate eye distance: keep a certain distance, not close to the visual object, and keep an appropriate reading distance.

2. Correct sitting posture: keep the sitting posture upright, pay attention to the posture of the body and neck, and do not bow or sit sideways.

3. Reasonably arrange the rest time: get up every 40 minutes and exercise for 10 minutes. At the same time, take eye relaxation exercise to relieve eye fatigue.

Reasonable use of electronic products

Nowadays, teenagers' myopia is often related to long-term use of electronic products, so reasonable use of electronic products can effectively prevent myopia. Here are some suggestions:

1. Control the use time: reduce the time of continuous use of electronic products for a long time, and the daily use time should not exceed 2 hours.

2. Attention to posture: keep the correct posture when using electronic products, and do not lower your head or squint at the mobile phone or computer screen.

3. Use anti blue glasses: anti blue glasses can effectively reduce the damage to eyes.

Regular eye examination

Regular eye examination is very important for early detection of myopia and taking corresponding treatment measures. The following are some important inspection items:

1. Vision examination: regularly test your vision, so you can know whether your vision has declined in time.

2. Fundus examination: Through fundus examination, we can find out whether there is retinal detachment and other problems.

3. Refractive test: check the diopter to see if glasses or other correction methods are needed.

summary

Juvenile myopia is a common problem, but we can take a series of scientific methods to prevent and control myopia. Correct eye posture, reasonable use of electronic products, and regular eye examination are all important measures to effectively prevent myopia. Only by paying attention to teenagers' myopia and protecting their eye health can they have a bright future.
