Abstract
In certain embodiments, pupil-related characteristic detection or spectacles correction/adjustment based thereon may be facilitated. In some embodiments, a stimulus may be presented at a location on a first display portion of the user device at a first time to cause a first eye of a user to fixate on the location. A stimulus may be presented at the location on a second display portion of the user device to cause a second eye of the user to fixate on the location at a time subsequent to the first time. Movement of the first or second eye to fixate on the location on the respective first or second display portion in connection with the stimulus presentation at the second time may be determined. In response to the movement of the first or second eye exceeding a threshold movement amount, a user profile may be generated that includes the user's pupil distance.
