The interpupillary distance refers to the optimum distance between the eyepiece lens and the pupil of the eye. With Telescopic sights it is a question of trying out what is most comfortable for you. Most binoculars, as well as all DDoptics models, have so-called retractable EyecupsFor spectacle wearers, all DDoptics binoculars are equipped with retractable eyecups.
