Abstract:	A method for tear film break up measurements based on the degradation of corneal reflex images caused by dry spots is presented. The experimental setup, which is based on recording the corneal reflex image or the first Purkinje image, is described, as well as the method used to determine tear film stability by means of the associated break up time using the corneal reflex image degradation. Images obtained through simulations of the experimental setup are also shown.
