Effectiveness of a participatory eye care program in reducing eye strain among staff computer users in Thailand.

Abstract

BackgroundThe increased usage of computers results in a variety of health problems, particularly eye strain, which is the most common workplace complaint today.ObjectivesThis study aimed to evaluate the effectiveness of a participatory eye care (PEC) program by comparing eye care knowledge, attitude, and practice (KAP), as well as eye strain symptoms in staff computer users at Sukhothai Thammathirat Open University, Thailand.MethodsA participatory approach was held by organizing a meeting of 26 stakeholders to get opinions for developing the PEC program. The developed PEC program consisted of 3-hour training course on eye strain, rest breaks for 30 seconds every 30 minutes of computer use, and 15-minute rest break (in the morning and the afternoon) with integrated eye–neck exercises. Then, a quasi-experiment was conducted to evaluate the effectiveness of the PEC program. A total of 35 staff computer users enrolled in each of intervention and control groups for 8 weeks. Chi-square test and repeated measures analysis of variance were used for comparison of eye strain symptoms and the KAP scores.ResultsThe intervention was associated with reduction in percentage of eye strain. Significant differences were found between the intervention and the control groups at follow-up 1 (χ2=18.529, p-value <0.001) and follow-up 2 (χ2=18.651, p-value <0.001). The PEC program likely increased the beneficial effect on KAP scores between the groups and between times (p<0.05).ConclusionThe findings currently provide evidence to support a practical program developed through a participatory approach, which both researchers and computer users could apply to reduce eye strain.
