1. An apparatus for measuring eyelid tension, comprising:
a cylindrical body;
a measuring sensor formed on an outer circumferential surface of the body and configured to be disposed between an upper eyelid and a lower eyelid of a person to be measured to measure the eyelid tension such that the upper eyelid and the lower eyelid come into contact with the measuring sensor and press the measuring sensor; and
a contact part formed at a longitudinal distal end of the body to come into contact with an eyeball of the person to be measured between the upper eyelid and the lower eyelid.
