bjective: The purpose of our work was to study and compare the cornea and tear film of people and sheepinhabiting in a region of Argentinean Patagonia (PATG), and in a geographically and climatically different region inthe Argentinean Pampa (CAPT).Methods: Using cross sectional study, corneal examinations were performed in people and Merino sheepinhabiting PATG and CAPT regions, respectively. All people completed a questionnaire related to work activity, diet,and the use of hats or sunglasses during their life. Eyes from all participants were examined with a portable handheldslitlamp biomicroscope (BM) to evaluate corneal appearance, epithelium integrity, and transparency. Later on,in a subgroup of participants we studied eyeblinking frequency (EBF), ocular surface staining (FS), breakup time(BUT), Schirmer Tear Test (STT), corneal structure using confocal laser scanning microscopy (CLSM) and lightmicroscopy (LM), and concentration
