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.

Conditions

• Digital Eye Strain

Intervention / Treatment

• Other: Exposure
• Diagnostic Test: Orthoptic assessment (Outcome measure)
• Diagnostic Test: Tear film Break Up Time (BUT) test (Outcome measure)

Primary Outcome Measures

• Prevalence of Digital Eye Syndrome (Immediately after subject enrollment, up to 1 week (single point collection))
  To verify the existence or absence of digital fatigue syndrome in higher education students. For this purpose, the Computer Vision Syndrome Questionnaire will be used. To verify the existence or not of digital fatigue syndrome in higher education. The Computer Vision Syndrome Questionnaire (CVS-Q) will be applied, which is composed of 16 x 2 questions, to assess the symptoms and their intensity. This questionnaire makes it possible to classifying CVS as asymptomatic and symptomatic.
