Moderate evidence was observed for : ( 1 ) no effect of workstation adjustment , ( 2 ) no effect of rest breaks and exercise and ( 3 ) positive effect of alternative pointing devices .
For all other interventions mixed or insufficient evidence of effect was observed .
Conclusion : Few high quality studies were found that examined the effects of interventions in the office on musculoskeletal or visual health
Background : The literature examining the effects of workstation , eyewear and behavioral interventions on  musculoskeletal and visual symptoms among computer users is large and heterogeneous .
Methods : A systematic review of the literature used a best evidence synthesis approach to address the general question “ Do office interventions among computer users have an effect on musculoskeletal or visual health ? ”
Comparative randomised controlled clinical trial of a herbal eye drop with artificial tear and placebo in computer vision syndrome.
A comparative r and omised double masked multicentric clinical trial has been conducted to find out the efficacy and safety of a herbal eye drop preparation , itone eye drops with artificial tear and placebo in 120 patients with computer vision syndrome . Patients using computer for at least 2 hours continuosly per day having symptoms of irritation , foreign body sensation , watering , redness , headache , eyeache and signs of conjunctival congestion , mucous/debris , corneal filaments , corneal staining or lacrimal lake were included in this study . Every patient was instructed to put two drops of either herbal drugs or placebo or artificial tear in the eyes regularly four times for 6 weeks . Objective and subjective findings were recorded at bi-weekly intervals up to six weeks . Side-effects , if any , were also noted . In computer vision syndrome the herbal eye drop preparation was found significantly better than artificial tear ( p < 0.01 ) . No side-effects were noted by any of the drugs . Both subjective and objective improvements were observed in itone treated cases . So , itone can be considered as a useful drug in computer vision syndrome
