Abstract
Some demonstrative embodiments include apparatuses, systems and/or methods of determining a pupillary distance. For example, a product may include one or more tangible computer-readable non-transitory storage media including computer-executable instructions operable to, when executed by at least one computer processor, enable the at least one computer processor to implement operations of measuring a pupillary distance between pupils of a user. The operations may include receiving a captured image comprising first and second reflections of a light of a light source, the first reflection comprising a reflection of the light from a first pupil of the user, and the second reflection comprising a reflection of the light from a second pupil of the user; and determining the pupillary distance based on locations of the first and second reflections in the captured image and an estimated distance between an image capturing device and pupils of the user, when the image is captured.
