Popis: The work presented in the paper describes a mechatronic test stand and technique employed to determine the accuracy of a system developed by the authors to assist optometrists in measuring parameters used in the customization of progressive lenses, as well as regular lenses. The system aims to offer information about interpupillary distance, pantoscopic angle, and vertex distance, as well as measurements useful in correctly mounting the lenses in the frames. This is conducted by attaching a marker support system to the user’s frame and determining the user’s dimensions by using image acquisition techniques performed via a custom application built for this purpose. In this paper, a test mannequin is used to determine the accuracy of the system, with measurements being compared to those obtained by using classic methods. This method is used to determine the accuracy of the measurements in a controlled environment. Following the good results obtained in this paper and pending some improvements to the application, clinical tests will be performed on a small scale in selected optometrist offices.
