Visual Functioning and Mental Health in the Digital Age.

: Considering the omnipresence of digital devices in every aspect of our lives, and from an increasingly younger age, digital eye strain (DES) and dry eye disease (DED) have become a global concern. The main objective of this paper is to conduct a systematic review of the literature on the relationship between digital screen use and ocular surface health, as well as the potential negative impact of impaired visual functioning on certain aspects of mental health and daily performance. : Using the PRISMA method, the screening and study selection process resulted in the inclusion of 15 papers published in the electronic databases PubMed and WoS. : The findings highlight the prolonged use of digital devices and the concerning prevalence of DED or DES symptoms across different populations. A significant relationship was found between DED and DES symptoms and mental health outcomes, including depression, anxiety, and stress. Furthermore, higher frequency and severity of DED or DES symptoms was associated with reduced sleep quality and difficulties in certain aspects of daily functioning. : Given the ongoing exposure to digital devices and increasing prevalence of DED and DES symptoms across all age groups, there is a need to design interventions and programs focused on preserving ocular surface health and improving subjective well-being. The multifaceted impact these symptoms have on physical and mental health, as well as daily functioning, requires a holistic approach, integrating ergonomic interventions, digital hygiene, and mental health support.
