Human body puncture is called an alternative art in medicine, which is different from medical puncture. It is a beauty trend rising in Europe and America. People boldly pierce the skin or cartilage of the navel, lips, tongue, eyebrows and earlobes, and even pierce accessories in the private parts of the human body, and decorate the human body with various dazzling metal nail rings to show their individuality and flaunt their uniqueness. Nowadays, eyeball jewelry has become the latest fashion in Holland. Under anesthesia, tiny jewels called "gem eyes" are implanted into the mucous membrane of the eyes by ophthalmologists.
