In routine optometry clinics, anxious parents frequently ask: "Doctor, my child's myopia increased by 100 diopters this year. Is that normal? Do we need immediate intervention?"

Today, we'll comprehensively address parents' top concern on myopia prevention by aligning with national guidelines. This includes the science behind myopia progression, key risk factors, evidence-based intervention strategies, and common misconceptions to help you avoid pitfalls in your child's eye care journey.

Is a 100 diopter increase in myopia per year within the normal range?

Based on the authoritative standards for myopia prevention and control in children and adolescents issued by the National Health Commission of China:

处于身体发育期的孩子，每年近视涨幅 50～75 度是相对稳妥的区间；一旦年度涨幅超过 50 度，就属于进展性近视范畴；一年加深 100 度，增长速度明显偏快，并不健康，需要及时介入管控中华人民共...。

当然不能一概而论，两种特殊情况可短暂放宽看待：

For children newly diagnosed with low myopia, small fluctuations in prescription during the eye's adaptation phase are normal. A short-term increase is common, but if the prescription exceeds 100 degrees for two consecutive years, it requires attention.

In preschool-aged children, eye growth is rapid, with an initial rate slightly higher than in older children. However, even so, it is not recommended to sustain an annual increase of 100 diopters over the long term.

绝大多数一年暴涨 100 度的孩子，根源都是长期近距离用眼超负荷、户外活动严重不足，任由速度持续下去，很容易早早发展成高度近视，后续会提升眼底病变风险。

二、近视到底是怎么悄悄找上门的？

Many parents focus solely on the prescription number without understanding the core causes of myopia:

我们的眼睛好比一台精密照相机，健康状态下，外界光线能够精准汇聚在视网膜上，视物清晰。

If this elongation exceeds a normal rate, light focuses in front of the retina, causing distant objects to appear blurry. This leads to the formation of true myopia. Source: State Council of China.

眼轴增长不可逆，身高停止发育后眼轴才会慢慢趋于稳定。发育期眼轴长得越快，近视度数涨得就越猛，这也是小学、初高中阶段孩子近视飙升的关键原因。

三、五大核心因素，推着孩子度数一路上涨

1. Innate genetic foundation

父母双方均为高度近视，孩子近视的发病概率会大幅提升；遗传相当于埋下了近视易感体质，后天不良用眼环境会加速近视显现与加深。

2. Reading/writing distance too close; incorrect posture

Many children hold their heads too close to their desks while doing homework. This forces their eyes to remain in a state of constant, near-focus strain, leading to cumulative eye fatigue that directly stimulates excessive elongation of the eyeball.

胸口离桌沿一拳、眼睛离书本一尺（约 33cm）、握笔指尖距离笔尖一寸，昏暗灯光、躺卧看书、坐车看书都会加重眼部负担新华网。

3. Severe lack of daytime outdoor activities

学业压力挤占了大部分室外时间，是当下近视高发首要诱因。

Outdoor natural light stimulates dopamine secretion in the retina, effectively inhibiting excessive elongation of the eyeball. It is widely recognized as the most cost-effective prevention method. Authoritative guidelines recommend at least 2 hours of outdoor activity during daylight each day; it remains effective even on cloudy days. During breaks, step outside to gaze into the distance and relax your eyes. Guangxi Zhuang Autonomous...

4. 电子产品无节制使用

Phones, tablets, and TVs are part of daily life, but staring at screens for long periods drastically reduces blinking frequency, leading to dry, sore eyes and sustained strain.

5. 双眼视功能不协调

斜视、隐斜、双眼融合功能偏弱等问题，会造成孩子看东西易重影、串行、眼酸疲惫，视觉系统始终处于费力代偿状态，间接加快近视发展，这类问题大多需要专业视光检查才能发现。

IV. Myopia progressing too fast? 4 science-backed intervention steps

True myopia is irreversible. The core goal is to slow the progression of refractive error and control axial elongation, preventing the development of high myopia. Effective management consists of four key components:

1. 精准专业验光，筑牢防控基础

孩子验光万万不可随意应付，精准的数据是配镜、制定防控方案的前提。

鲸目眼镜采用蔡司 11 步标准化数字化验配体系，涵盖客观屈光检测、KEELER 专业检影验光、ZEISS VISUPHOR 500 精细化综合验光全套流程；所有验光师均持有国家高级验光资质，从业经验充足，可完整排查度数、眼轴、角膜曲率、双眼视功能等多项眼部数据，结果更严谨可靠。

2. Choose myopia control lenses on demand for personalized eyewear.

Current myopia control methods each suit different groups. Choose based on your child's eye conditions.

Defocus spectacle lenses: Widely applicable; use specialized optical design to create peripheral myopic defocus, slowing axial elongation. Suitable for most school-aged children with myopia.

OK 镜（角膜塑形镜）：夜间睡觉时佩戴，白天无需戴镜就能拥有清晰视力，控近视效果突出，但对眼部条件、个人卫生护理、依从性要求较高，需严格遵医嘱佩戴复查；

Standard single-vision lenses provide clear vision but offer minimal myopia control. Jingmu eyewear creates a personalized vision management plan for children by integrating prescription data, daily visual demands, and age-specific factors.

3. 日常用眼行为长久管控

防控重在日复一日的坚持，简单几条准则一定要落实：

遵循 20-20-20 法则：近距离用眼每 20 分钟，抬头眺望 6 米外远处至少 20 秒；连续看书、写作业不超过 40 分钟，休息 10 分钟；

严格恪守一拳一尺一寸坐姿，保证书桌光线充足柔和；

Reduce time spent on mindless video scrolling and gaming; replace fragmented moments with outdoor walks or exercise.

4. Regularly review progress and adjust the plan dynamically

Myopia management is a long-term, dynamic process—not a one-time fix after getting glasses.

Schedule vision, refraction, and axial length checkups every 3–6 months. Monitor data trends; if changes accelerate, adjust your myopia control strategy promptly.

Whale Vision creates a personalized myopia development profile for each child, capturing every exam data point. Parents can easily track vision changes over time, while professionals use this data to continuously optimize management plans.

5. The 3 Most Common Fatal Mistakes Parents Make

误区 1：初期看不清不用管，熬一熬就好了

很多家长觉得孩子偶尔眯眼、视物模糊只是没休息好，迟迟不做检查；等到度数涨到两三百度才着急就诊，早已错失近视早期最佳管控窗口，后续涨幅很难压下来。

Myth 2: Expensive lenses aren't a cure-all; daily eye habits still matter.

再好的防控眼镜都只是辅助工具。倘若依旧天天近距离久坐、沉迷电子产品、不出门活动，镜片的控度效果会大打折扣，良好用眼习惯才是近视防控的核心。

误区 3：网上随意网购眼镜，贪图便宜省事

网购眼镜无法做专业验光与双眼视功能检查，度数、瞳距、散光轴位容易出现偏差；不合适的眼镜会持续加重眼疲劳，反倒加速近视加深，得不偿失。

总结

A child's myopia increased by 100 degrees in a year, indicating a relatively fast progression that requires immediate parental attention.

Myopia control for children is never just about a pair of glasses. It requires a comprehensive system: precise prescription and fitting at professional facilities, sufficient daily outdoor activity, proper eye-use habits, and regular monitoring of axial length and refractive error—all are essential.

日常接诊中我们发现，多数家长一味看重镜片品牌，却常常忽略用眼作息、双眼视觉功能、长期追踪管理这些关键环节。希望各位家长摆正心态，科学管控视力，守护孩子长久清晰视界。
