Effectiveness of 20-20-20 Rule and Bates Exercises in Computer Vision Syndrome on Desktop Workers

Abstract

The study aimed to compare the effectiveness of the 20-20-20 rule and Bates exercises in reducing symptoms of Computer Vision Syndrome (CVS) among desktop workers. A total of 42 participants were randomly divided into two groups: Group 1 (20-20-20 Rule) and Group 2 (Bates Exercises). Pre- and post-intervention assessments were conducted using the CVS-Q and Likert Scales. Statistical analysis revealed significant improvement within both groups (p < 0> 0.05), suggesting that both methods were equally effective in improving visual comfort and reducing eye strain.

DISCUSSION

Both the 20-20-20 rule and Bates exercises effectively improved CVS symptoms. Participants demonstrated a significant decrease in both Likert and CVS total scores post-intervention. Although the within-group changes were significant, the between-group differences were not, indicating comparable effectiveness. These findings align with earlier studies suggesting that frequent eye relaxation and screen breaks reduce ocular strain and improve productivity.

CONCLUSION

The study concludes that both 20-20-20 rule and Bates exercises are effective non-pharmacological interventions to reduce Computer Vision Syndrome among desktop workers. Both methods can be recommended as workplace wellness strategies to minimize eye strain and visual fatigue.
