Brief Summary
Photobiomodulation therapy, that is, Low-level red-light technology provides a new and innovative myopia control approach. This strategy enables relatively high energies of light to be delivered at much shorter durations of exposure to induce the myopia control effect. The efficacy of the low-level red-light technology has been proven in a Chinese populationb for the recent 3 years with evidence based papers and amazing results. However, there's not yet evidence to demonstrate the relationship between the dose response effect of photobiomodulation therapy on myopia control at the different age lever.

Study Arms (4)
Moderate irradiance of PBM therapy to myopia
EXPERIMENTALThe PBM therapy irradiance is about 0.60mW. It is asked subjects to look at the light binocularly with fusion through the pupils with natural pupils. The distance between the light and the pupils is about 5\~10cm. The treatment of each session is 3 minutes and twice daily administration while the interval time between two session is equal or larger than 4 hours with twice daily administration.
Extra low irradiance PBM therapy group
SHAM COMPARATORThe PBM therapy irradiance is about 0.37mW. It is asked subjects to look at the light binocularly with fusion through the pupils with natural pupils. The distance between the light and the pupils is about 5\~10cm. The treatment of each session is 3 minutes and twice daily administration while the interval time between two session is equal or larger than 4 hours with twice daily administration.
high lever PBM therapy group
EXPERIMENTALThe PBM therapy irradiance is about 1.20mW. It is asked subjects to look at the light binocularly with fusion through the pupils with natural pupils. The distance between the light and the pupils is about 5\~10cm. The treatment of each session is 3 minutes and twice daily administration while the interval time between two session is equal or larger than 4 hours with twice daily administration.
Control
NO INTERVENTIONWithout PBM therapy group.
Interventions
This light is Narrow-Band, Long-Wavelength Lighting with three different illumination (400lux, 800lux, 1200lux) or irridiance (1.2mW, 0.6mW, 0.37mW) respectively. And the wavelength is 650nm. It allows biocular therapy.
Eligibility Criteria
You may qualify if:
- Myopia or near Myopia with younger age
- Without other intervention of myopia control, including atropine, Misight contact lens, special design lens to control myopia, orthokeratology and other red light devices.
- Follow-up at least once
- With baseline data of ocular parameters before the follow-up
You may not qualify if:
- Photophobia
- Allergy to red light
- Severe ocular progressing diseases or systemic diseases
- The data is unacceptable with reasonable explanations
