The frame of the One loupe glasses combines the stability of titanium with the lightness of aluminium. The high-definition optical system is made to measure based on individual requirements, such as pupillary distance and working distance of the user. The spectacles therefore provide an optimal fit and create ideal working conditions for surgeons and dentists. Furthermore, optional accessories such as side protectors, a headband and the connection with the illumination system are designed to offer a comfortable integrated ensemble.
