1. A method for determining parameters for spectacle fitting, comprising:
detecting depth information in relation to a user's head with a depth information detection unit;
determining parameters for spectacle fitting based on the depth information,
wherein the depth information detection unit is a light field camera, a time-of-flight sensor, or a camera-based infrared depth sensor,
wherein an infrared pattern is generated by a projection system and, with a scene thus illuminated being recorded by an infrared camera, a depth of objects in the scene is averaged, or wherein the depth information detection unit operates based on infrared radiation or based on patterns in a visible light range, or wherein the depth information detection unit measures a distance by optical triangulation;
repeating detecting the depth information a number of times;
averaging over a plurality of detected items of depth information; and
rejecting the plurality of detected items of depth information, which satisfy predetermined criteria.
