Arms Assigned Interventions
Experimental: Standardized Chinese ocular exercise
The participants are trained with standardized Chinese ocular exercise which contains accurate positions of acupuncture points and appropriate pressure on the points.
Other: Chinese ocular exercise
A kind of massage around the acupuncture points around the eye.
Sham Comparator: Nonstandardized ocular exercise
The participants are trained with nonstandardized ocular exercise performed on wrong positions where no acupuncture points at all.
Other: Chinese ocular exercise
A kind of massage around the acupuncture points around the eye.
No Intervention: Eye closure
The participants are told to close eyes and don't do ocular exercise at all.

Detailed Description:
Myopia is a public health problem worldwide, especially in some Asian countries like China, Singapore, and Japan. Chinese ocular exercise, originating in 1963 with the theory of Traditional Chinese Medicine, is a kind of massage on acupuncture points around the eye to prevent myopia and alleviate visual fatigue. The exercise has been spread as a community ritual and living habit of primary and high school students for nearly half a century. However, the prevalence of myopia in Chinese children increased remarkably in recent years. Therefore, the efficacy of Chinese ocular exercise on preventing myopia or alleviating visual fatigue is widely questioned. Evidence from clinical trials of high level is needed to clarify that whether Chinese ocular exercise is effective in slowing and preventing myopia progression, or at least in part in easing the symptoms related to myopia and visual fatigue.
