随着暑假的来临，我国各地天气逐渐炎热，孩子们的户外活动时间缩短，加之长时间的室内近距离用眼和不规律的生活作息，这些因素都可能导致儿童青少年的视力问题加剧。因此，预防和控制近视成为了家长们关注的焦点。为了帮助儿童青少年健康度过暑假，我们总结了以下12个字的防控近视秘诀，希望对家长们有所启示。
**一、充足户外活动**：研究表明，每天至少两小时的户外活动能有效降低儿童青少年近视的风险。家长应鼓励孩子在暑假期间多参与户外活动，如篮球、足球、跑步等，让眼睛在自然光线下得到充分休息。
**二、合理用眼时间**：控制室内近距离用眼的时间，每用眼40-50分钟后，远眺20秒至30秒，让眼睛得到放松。使用电子产品时，遵循“20-20-20”原则，即每20分钟看20英尺（约6米）外的物体20秒，减少对眼睛的伤害。
**三、规律生活作息**：保证充足的睡眠，小学生每天应睡足10小时，初中生9小时，高中生8小时。规律的作息有助于眼睛和身体的健康发育，避免因熬夜导致的视力问题。
**四、正确阅读姿势**：保持阅读距离适中，一般应在30厘米左右。光线要充足且柔和，避免在过暗或过亮的环境下阅读，减少对眼睛的刺激。
**五、定期视力检查**：家长应定期带孩子进行视力检查，及时了解视力状况，一旦发现视力下降或出现视力问题，应及时就医，避免近视的进一步发展。
**六、科学用眼环境**：保持室内光线明亮均匀，避免反光，使用符合标准的护眼灯具，减少对眼睛的伤害。
通过上述六个方面，家长们可以有效地帮助孩子在暑假期间防控近视，保持良好的视力健康。让我们一起努力，让孩子们在享受暑假的同时，也能拥有明亮的未来。

### Healthy Summer Vacation:防控近视, Follow These 12 Words
As the summer vacation rolls in, with temperatures rising across the country and children spending less time outdoors, coupled with prolonged indoor, close-up viewing and irregular daily routines, these factors can exacerbate vision issues in children and adolescents. Therefore, preventing and controlling myopia has become a key concern for parents. To assist children and adolescents in maintaining their health during summer, we have compiled a set of 12-word tips for myopia prevention, hoping to offer guidance to parents.
**1\. Plenty of Outdoor Activities:** Research indicates that spending at least two hours daily in natural light can significantly reduce the risk of myopia in children and adolescents. Parents should encourage children to participate in outdoor activities such as basketball, football, or running during the summer, allowing their eyes to rest in the natural light.
**2\. Manage Screen Time:** Limit the duration of indoor, close-up viewing, taking a 20-second to 30-second break every 40-50 minutes of screen time, and looking at something 20 feet away. Adhere to the “20-20-20” rule when using electronic devices, spending 20 seconds looking at something 20 feet away every 20 minutes, to minimize eye strain.
**3\. Regular Sleep Schedule:** Ensure sufficient sleep, with 10 hours for elementary school students, 9 hours for middle school students, and 8 hours for high school students. Regular sleep patterns are crucial for eye and overall health development, avoiding vision issues caused by late-night activities.
**4\. Correct Reading Posture:** Maintain a reading distance of around 30 centimeters. Ensure adequate and soft lighting, avoiding reading in dim or overly bright environments to reduce eye strain.
**5\. Regular Eye Examinations:** Parents should regularly take children for eye exams to monitor their vision status. Promptly seek medical attention if vision deteriorates or any vision issues are detected, to prevent the progression of myopia.
**6\. Optimal Lighting Environment:** Keep indoor lighting bright and even, avoiding glare, and use eye-friendly lighting that meets standards to minimize damage to the eyes.
By following these six aspects, parents can effectively help their children prevent myopia during summer, maintaining good eye health. Let’s work together to ensure that children can enjoy their summer while also securing a bright future for their eyesight.
