Brief Summary

To assess whether Chinese ocular exercise is effective in altering distant and near visual acuity, ocular accommodation and visual symptoms in myopic teenager, and thus might have the possibility of slowing myopia progression in teenager through a weak but long-term effect.

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.
