A glasses apparatus is provided. The glasses apparatus includes: a first retarder which delays phases of a first image and a second image which are output from a display apparatus, a second retarder which delays the phases of the first image and the second image in a direction different from that of the first retarder, a first shutter glass and a second shutter glass which change polarization properties of the first image and the second image, optical axes of which are rotated according to whether power is supplied or not, and a controller which controls to selectively supply the power to the first shutter glass and the second shutter glass so that a user selectively views the first image and the second image.
