Abstract
The invention relates to an automatic pupillometer comprising a light source suitable for generating a corneal reflection on at least one of the eyes of an individual facing first and second windows, a collimator lens serving at least to position the light source to correspond to far vision of the individual, a detection receiver for automatically locating said reflection, and a calculator for calculating the pupillary distance of said individual. According to the invention, the pupillometer also comprises a third window where the eye of an observer responsible for the measurement is designed to be placed in the vicinity of the focus of said lens so as to view and verify measurement conditions.
