Influence of Face Masks on the Use of Contact Lenses

Abstract: Background: The COVID-19 epidemic is largely controlled by the use of face masks. The use of a face mask has been indicated as a strong cause of dry eye, although it is not yet described in the literature. This study aims to compare the impact of the use of masks on the visual quality of patients. The symptoms in the human eye intensified during the pandemic versus the symptoms before the pandemic, in a Portuguese population.
