赵阳医生（赵阳）提出的 “4L 综合疗法”（4L综合疗法） is a Chinese myopia-control / vision-training concept. The exact content varies depending on the clinic/material, but generally it combines several approaches around eye habits, visual training, and myopia management. The “4L” usually refers to four aspects such as:
- Light（光环境） — improve reading/work lighting conditions
- Look（用眼方式） — manage near work distance, breaks, posture
- Lens（镜片/光学矫正） — glasses, special lenses, myopia-control lenses
- Lifestyle（生活方式） — outdoor time, eye-use habits, sleep, etc.
(Some versions use slightly different words; the key idea is a multi-factor intervention.)
Does it “cure” myopia?
For true axial myopia (眼轴变长), current mainstream ophthalmology consensus is:
No proven therapy can reverse the elongated eyeball and permanently cure established myopia.
Once the eye grows longer, glasses/contact lenses/surgery can correct the focus, but they usually do not “restore” the original eye shape.
What can work:
1. Myopia control (evidence-supported)
These can slow progression:
- More outdoor time (especially children)
- Low-dose atropine (commonly 0.01%–0.05%, depending on region and patient)
- Orthokeratology (OK lenses)
- Myopia-control soft contact lenses
- Defocus spectacle lenses (e.g., DIMS/HAL designs)
2. Vision training
Some exercises can improve:
- accommodation flexibility
- eye strain symptoms
- binocular coordination
But they generally do not shorten axial length.
3. Adult myopia
For someone like you (your previous prescription history: roughly L -2.5D, R -4.25D in 2024), the question is usually not “cure”, but:
- prevent further progression
- monitor retina health
- optimize correction
- manage presbyopia later
At age ~30+, axial myopia progression is usually much slower than in children, unless there are special factors.
My view
“4L” is probably useful as a comprehensive eye-care framework, especially for children who are still growing. But if marketing says:
“治愈近视 / 摘掉眼镜 / 恢复眼轴”
that claim goes beyond current evidence.
A good analogy:
- Training + lifestyle = like maintaining engine conditions
- Myopia-control lenses/atropine = like limiting engine wear
- Cure = rebuilding the engine block (eye length), which we currently cannot reliably do
