Abstract

The invention relates to a device (10) for determining the optical parameters of a user comprising: at least two image recording devices (14, 16), which are configured and arranged to respectively generate image data of at least sub-sections of the head of the user (30); a data processing unit comprising a user data determination device, which is configured to use the generated image data to determine user data relating to at least one sub-section of the head, or at least one sub-section of a system placed on the head that supports a pair of glasses (38) of the user (30) in a normal position of wear, the user data containing the three-dimensional location information of predetermined points in the head sub-section or the system sub-section and comprising a parameter determination unit, which is configured to determine at least some of the optical parameters of the user (30); a data output device, which outputs at least some of the determined optical parameters of the user (30). The invention also relates to an additional device, a corresponding method and a computer program.
