Use of information technology hardware given new heights to professional success rate and saves time but on the other hand its harmful effect has introduced an array of health related complaints causing hazards for our human health. Increased use of computers has led to an increase in the number of patients with ocular complaints which are being grouped together as computer vision syndrome (CVS). In view of that, this study was undertaken to find out the ocular complaints and the factors contributing to occurrence of such problems in computer users.
To evaluate the factors contributing to Ocular complaints in computer users in Teerthanker Mahaveer University, Moradabad, U.P. India.
Community-based cross-sectional study of 150 subjects who work on computer for varying period of time in Teerthanker Mahaveer University, Moradabad, Uttar Pradesh.
Two hundred computer operators working in different institutes offices and bank of were selected randomly in Teerthanker Mahaveer University, Moradabad, and Uttar Pradesh. 16 were non responders 18 did not come for assessment and 16 were excluded due to complaints prior to computer use making no response rate Twenty-one did not participate in the study, making the no response rate 25%. Rest of the subjects (n = 150) were asked to fill a pre-tested questionnaire, after obtaining their verbal consent Depending on the average hours of usage in a day, they were categorized into three categories viz. <2 hrs, 2-6 hrs, >6 hrs of usage. All the responders were asked to come to the Ophthalmic OPD for further interview and assessment.
Simple proportions and Chi-square test.
Among the 150 subjects studied major ocular complaint reported in descending order were eyestrain. (53%). Occurrence of eye strain, ( 53.8%), itching ( 47.6%) and burning (66.7%) in subjects using computer for more than 6 hours. distance from computer screen with respect to eyes, use of antiglare screen, taking frequent breaks, use of LCD monitor and adjustment of brightness of monitor screen bear a significant association with these ocular complaints in computer users.
Eye strain is the most common ocular complaints among computer users working for more than 6 hours a day. We also found that maintaining ideal distance from screen, keeping level of eyes above the top of screen, taking frequent breaks, using LCD monitors and using antiglare screen and adjusting brightness levels according to workplace reduced these ocular complaints to a significant level.
信息技术硬件的使用提升了职业成功率并节省了时间,但另一方面,其有害影响引发了一系列与健康相关的问题,对人类健康构成危害。计算机使用的增加导致眼部问题患者数量上升,这些问题被归为计算机视觉综合征(CVS)。鉴于此,本研究旨在找出计算机用户的眼部问题以及导致这些问题发生的因素。
评估印度北方邦莫拉达巴德蒂尔坦克·马哈维尔大学计算机用户眼部问题的影响因素。
对150名在印度北方邦莫拉达巴德蒂尔坦克·马哈维尔大学不同时长使用计算机的受试者进行基于社区的横断面研究。
在印度北方邦莫拉达巴德蒂尔坦克·马哈维尔大学随机选取200名在不同机构办公室和银行工作的计算机操作员。16人未回应,18人未前来评估,16人因在使用计算机前就有眼部问题而被排除,无回应率为25%。另有21人未参与研究,使得无回应率达到25%。其余受试者(n = 150)在获得口头同意后被要求填写一份预先测试过的问卷。根据他们每天的平均使用时长,将他们分为三类,即<2小时、2 - 6小时、>6小时。所有回应者被要求前往眼科门诊进行进一步访谈和评估。
简单比例和卡方检验。
在150名研究对象中,报告的主要眼部问题按降序排列为眼疲劳(53%)。使用计算机超过6小时的受试者中,眼疲劳发生率为53.8%,瘙痒发生率为47.6%,灼痛发生率为66.7%。计算机屏幕与眼睛的距离、使用防眩光屏幕、频繁休息、使用液晶显示器以及调整显示器屏幕亮度与计算机用户的这些眼部问题显著相关。
眼疲劳是每天使用计算机超过6小时的用户中最常见的眼部问题。我们还发现,保持与屏幕的理想距离、使眼睛水平高于屏幕顶部、频繁休息、使用液晶显示器、使用防眩光屏幕以及根据工作场所调整亮度水平可将这些眼部问题显著减少。
