A pair of stereoscopic glasses includes a pair of left and right stereoscopic rims connected to each other and respectively holding stereoscopic optical components used when observing a stereoscopic image, and a stereoscopic frame that includes stereoscopic temples extending rearward from the stereoscopic rims. The stereoscopic frame is provided with an engagement section that is brought into engagement with a rim or a bridge of a frame of glasses already worn by a user in a state where the stereoscopic optical components are positioned in front of lenses of the glasses so that the stereoscopic optical components are positionally maintained in front of the lenses of the glasses.
