Abstract

Dry eye disease is increasingly commom due to pronlonged digital screen usage ,which reduces blink rate and cause tear film instability.blue light from screens may worsen dry eye symptoms . Blue blocking glasses and built in eye care feature are popular interventions . This studt compares their effectiveness in managing DED in digital device users
 Objective: To compare the effectiveness of eye care features integrated into digital devices and blue-blocking glasses in reducing dry eye symptoms among frequent digital screen users.
Methods: A randomized controlled trial was conducted with 60 participants clinically diagnosed with dry eye disease. Participants were divided into two groups: Group A (n=30) used eye care features on their digital devices (blue light filter, night mode, dark mode), and Group B (n=30) used blue-blocking glasses. Assessments included Ocular Surface Disease Index (OSDI), Tear Break-Up Time (TBUT), and Schirmer’s Test I pre- and post-intervention over 3 months
Results: Both groups showed significant improvement in all outcome measures. However, Group A showed a greater reduction in OSDI score (14.2 vs. 8.7 points), greater TBUT increase (+2.7s vs. +1.5s), and higher improvement in Schirmer’s values (+4.3 mm vs. +2.4 mm). The differences between groups were statistically significant (p < 0.05).
Conclusion: Eye care features in digital devices are more effective than blue-blocking glasses in managing digital eye strain and dry eye symptoms. These findings support screen-based ergonomic interventions as a practical solution for digital device users.
