Effect of Ophthalmic exercise on severity of Visual Acuity and Neck Disability amongst IT professionals: an Experimental study

Abstract

Background: Information Technology (IT) professionals are highly susceptible to Computer related vision problems and work-related musculoskeletal disorders due to prolonged computer use. Visual fatigue, reduced visual acuity, and neck discomfort are among the most commonly reported complaints. Ophthalmic exercises have been suggested as a simple and cost-effective intervention to reduce these symptoms. Objective: To determine the effect of ophthalmic exercises on visual acuity and neck disability among IT professionals. Methods: An experimental study was conducted among 16 IT professionals aged 25–40 years who worked on computers for at least six hours daily and had a minimum of four years of work experience. Participants underwent a four-week ophthalmic exercise program combined with ergonomic advice. The intervention included blinking exercises, palming, flexing, focusing near and far, zooming, figure-of-eight movements, the 20-20-20 rule, and scheduled visual rest periods. Visual acuity was assessed using the Snellen Eye Chart, while neck disability was measured using the Neck Disability Index (NDI). Data were analyzed using SPSS version 20.0. Since the data were not normally distributed, the Wilcoxon Signed Rank Test was applied. Results: Significant improvements were observed in Visual acuity and Neck disability following the intervention. Visual acuity improved significantly in both eyes (p < 0.05). Neck Disability Index scores showed a highly significant reduction after treatment (p < 0.001), indicating decreased neck-related functional limitations. Participants reported reduced eye strain, visual discomfort, and neck pain following the intervention. Conclusion: Ophthalmic exercises combined with ergonomic advice are effective in improving visual acuity and reducing neck disability among IT professionals. These exercises may serve as an accessible and non-invasive strategy for managing computer-related visual and musculoskeletal complaints
