Abstract
Some demonstrative embodiments of the invention include devices and/or methods of measuring a personalized lens-orientation value for a spectacle frame supporting a pair of lenses. The device, according to some demonstrative embodiments, may include a pair of orientation-measuring mechanisms, each mechanism adapted to measure a value corresponding to an orientation of a surface of a respective one of the lenses relative to a reference axis. The device may also include an adjustable positioning mechanism to adjust a distance between the pair of orientation-measuring mechanisms according to an inter-pupil distance of the user. Other embodiments are described and claimed.
