Abstract

With a primary focus on their effects on tear dynamics and ocular health, this research effort addresses the hyperlink between pre and post digital screen usage, time of day, and tear dynamics. The desired outcomes of the eye health metrics divulge that post-digital screen exposure significantly reduces mean tear production values across all conditions (p < 0.05), with this impact intensifying as the day progresses. These observations show the interplay between digital stress and circadian alteration in tear dynamics, bringing attention to the relevance it has become for eye care professionals to contemplate temporal variations while preventing dry eye syndrome. Reduction in Schirmer value, tear breakup time and tear meniscus height suggest decreased tear production or lack of distribution across the eye possibly due to prolonged screen time causing reduced blink rate and increased evaporation. Individualized approaches that address these variables may enhance the effectiveness of treatment for people who suffer from dry eye disorders and ocular discomfort brought on by screen use.
