Brief summary: The goal of this observational study is to determinate the association between DES and changes in binocular vision and ocular surface. in higher education students in the area of health technologies. The main questions it aims to determine the prevalence of Digital Eye Syndrome (DES); the association between DES and changes in binocular vision and ocular surface; whether the time of use and the type of electronic devices influences the degree and type of symptoms of DES; and to determine whether there is an association between the type of ametropia and the symptoms of DES. Participants will have to answer 3 questionnaires (the Computer Vision Syndrome Questionnaire; the Convergence Insufficiency Symptoms Survey, and the Dry Eye Questionnaire (DEQ-5)) and then they will perform an orthoptic assessment and an assessment of the ocular surface with the tear film Break Up Time (BUT) test.
