PURPOSE: A lens set for a 3-dimensional image is provided to offer comfort to a user's eyes and obtain a high power by refracting an optical path to a focus point. CONSTITUTION: A plurality of 3-dimensional images(11,12) are printed on a left side face(602) of each page in an inside of a book(600). A plurality of eccentric lenses(100,200) are adhered on a cover(601) of a left side of the book(600). A plurality of extension parts(603,604) and a curved part(605) are formed in order to view 3-dimensional images(11,12) through the eccentric lenses(100,200). The length extended from the left cover(601) is determined by a focusing distance between the 3-dimensional images(11,12) and the eccentric lenses(100,200) when the eccentric lenses(100,200) are adhered on the left cover(601) of the book(600) in order to view the 3-dimensional images(11,12).
