An artificial eyelash structure includes a mounting member having a bonding portion for adhering to an eyelid and a bendable portion for enabling the bonding portion to be curved into a smoothly arched shape when bending the bonding portion upwards or downwards, and multiple eyelashes connected with the mounting member. The artificial eyelash structure is prepared by: forming a mounting member from a thin film, and then processing the thin film of the mounting member into a bonding portion and a bendable portion such that the bendable portion enables the bonding portion to be bent upwards or downwards, and then connecting eyelashes with the mounting member. A method of using an artificial eyelash structure includes the step of preparing an artificial eyelash structure having a mounting member and eyelashes connected with the mounting member, the step of bending the mounting member along the connection between the mounting member and the eyelashes to form a bonding portion; and the step of curving the bonding portion into a smoothly arched shape and then using a glue or double-sided adhesive to adhere the bonding portion to an eyelid.
