Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Exposure

Higher education students from health technologies field exposed to digital devices.

Intervention Type OTHER

Orthoptic assessment (Outcome measure)

The orthoptic assessment is a non-invasive assessment that will last for 30 min to determine visual parameters related to binocular vision. It will be carried out by the research team in the orthoptics and vision sciences laboratories of the Lisbon School of Health Tecnology.

Intervention Type DIAGNOSTIC_TEST

Tear film Break Up Time (BUT) test (Outcome measure)

The BUT test is a tear film rupture assessment test that allows the stability of the tear film to be evaluated. To perform these tests, it is necessary to instill fluorescein and then it is observed in the slit lamp under illumination with a cobalt blue filter, to count the break-up time.

Intervention Type DIAGNOSTIC_TEST
