Background

The periocular massage device is an electric massage instrument specifically designed for periocular muscles and delicate tissues around the eye. In modern society, problems such as eye fatigue, dryness and maculopathy caused by long-time use of electronic products such as computers and mobile phones are becoming more and more common. The background of application of periocular massaging devices is primarily to provide relief and treatment for these problems.

According to the theory of traditional Chinese medicine, channels and collaterals and acupoints are arranged in the human body, and a plurality of acupoints such as Jingming acupoint, chengqi acupoint, sibai acupoint and the like are arranged in the region around eyes. By stimulating the acupoints, the channels and collaterals can be promoted to be unblocked, and the qi and blood running of the human body can be regulated, so that the effects of disease treatment and health care are achieved. Modern medical research has found that acupoints are physically rich in nerve, muscle and blood supply. Stimulation by some means can regulate the activities of the nerves and excite the curative effect of the body, thereby playing a role in treatment.

Weak current can be adopted to stimulate the acupoints around eyes to relieve fatigue, prevent myopia and improve eye function.
