An eyeglass member which is attachable to and detachable from a frame mounted to a head of a user, including: a right-eye polarized-light modulation layer which has a first optical axis and modulates polarized light at a right-eye region positioned in front of a right eye of the user; a left-eye polarized-light modulation layer which has a second optical axis different from the first optical axis and modulates polarized light at a left-eye region positioned in front of a left eye of the user; a polarizing layer which is laminated on and astride both the right-eye polarized-light modulation layer and the left-eye polarized-light modulation layer and has an absorption axis extending in an equal direction across the right-eye region and the left-eye region; and a labelling portion which indicates a left-right orientation for mounting to the frame.
