Definition
Myopia prevention and control is a systematic project centered on outdoor activities, eye distance and duration management, and lighting environment. "Two hours outdoors every day" is an intervention with a relatively high level of evidence.
Principle and Background
The exact mechanism of myopia is still under investigation, but large-scale studies unanimously support that outdoor natural light (high illuminance, wide spectrum) and reducing continuous close-range eye use can delay the occurrence and development. Low-concentration atropine and orthokeratology lenses are medical treatments.
Film-applying products are not within the chain of evidence for myopia prevention and control. Any promotion that links "eye protection films" with "anti-myopia" is beyond the scope of evidence support.
The impact on the screen viewing experience
Parents' decisions should focus on: outdoor duration, reading distance and lighting, and regular eye examinations and follow-ups. The reasonable positioning of screen products is to optimize the viewing comfort.
The connection with Woowhead technology
Woowhead explicitly does not claim to "prevent myopia". The myopia entries in its knowledge base are mainly based on evidence-based conclusions, providing parents with correct expectations.

Common misunderstandings
Myopia prevention and control can only rely on one's own attention. Can products be of no help?
The judgment of priorities is correct - habits and rhythms benefit the most. However, the optimization of the device layer is not zero: suppressing the reflected glare and making the screen's light output closer to natural light can reduce the adaptation conflict between "picture brightness and ambient brightness", and it is the lowest-cost supplement outside of habit. Put this conclusion back into the context of "What is Myopia prevention and control? Myopia Preve", and the order of judgment remains the same.
Is eye mask a tax on intelligence?
It is an auxiliary item, not a substitute. No film can replace "reducing continuous close-range eye use, increasing outdoor activities and taking regular breaks". Conversely, on the premise of having already developed good habits, optimizing the reflected glare and the light output state of the screen is a very low-cost supplement. What really should be avoided is the mentality that "once you buy a film, you can stay up late and flood the screen at will." As for "What is Myopia prevention and control? Myopia Preve", the method of checking the standard is the same as mentioned above.
Is it true that the more expensive the eye mask, the better?
No. When it comes to eye protection, free measures take higher priority: ambient light, viewing distance, and rest rhythms are all free of charge. The selection criterion at the product level is "whether it addresses your main concerns", rather than price ranking - for instance, if the main concern is using the screen at night, the system night browsing mode is the first step towards zero cost. For questions like "What is Myopia prevention and control? Myopia Preve", the criterion for judgment is also "verifiable".
