Effectiveness of Anti-Fatigue Contact Lens in Visual Display Terminals User with Digital Eye Strain

Abstract

Introduction: In this digital era, extensive screen use leads to digital eye strain, characterized by symptoms such as eye fatigue, dryness, and blurred vision. This study evaluates the effectiveness of Biofinity Energy’s anti-fatigue contact lenses in mitigating these symptoms and improving visual comfort.

Methodology: Patients with digital eyes strain were assessed for their visual functions before and after a 3 weeks trial period with the Anti-fatigue lenses. The Computer Vision Syndrome Questionnaire (CVS-Q) scores, amplitude of accommodation, and accommodative facility were perfomed on the patient. Schirmer’s test was also performed to evaluate tear production to ensure accurate assessment of dry eye conditions.

Results: Sixty nine participants aged between 18 to 35 years were included in the study out of which 33 were male (47.82%) and 36 were female (52.17%). The results indicated a significant reduction in CVS-Q scores from a mean of 9.15 before lens use to 6.98 after use of anti-fatigue lenses, highlighting improved symptom relief (p <0.01). The accommodative facility (OU) increased from 6.14 to 6.65 cycles per minute, suggesting enhanced focusing ease (p<0.01). However, the amplitude of accommodation showed minimal change, with an average increase from 9.69 to 9.95+ Dioptres (p<0.01). These findings suggest that while the Biofinity Energys lenses modestly improve accommodative facility and visual comfort but their effect on amplitude of accommodation is minimal. The observed improvement in CVS-Q scores underscores the lenses efficacy in alleviating discomfort associated with prolonged digital device use.

Conclusions: The results support the use of anti-fatigue lenses for reducing digital eye strain and enhancing visual ergonomics, although the impact on accommodative range remains limited.
