摘要
近年來台灣科技資訊發達，產業升級，生活水準大幅提昇，網際網路普及，台灣網路資訊中心統計上網人口高達1500萬人以上，且每天必須長時間使用電腦者越來越多，電腦的使用已從辦公室進入一般家庭中。然而，長期使用電腦對於操作人員的健康卻逐漸出現負面的影響，許多終端顯示器(video display terminal, VDT)的安全性及對人體健康方面的影響等相關研究陸續被發表。 電腦使用者之健康問題最常出現的是眼睛相關症狀，如眼睛疲勞、乾眼、刺激、灼熱感、紅眼、視覺模糊及複視等，吾人即把使用電腦所引起之上述眼部症狀統稱為電腦視覺症候群(Computer Vision Syndrome, CVS)，其屬於一種重複使力傷害(repetitive strain injury)，與工作環境之眩光、光源及特殊的視覺環境等有關，使用電腦的時間越長，產生眼睛視覺問題的機會越大。 有CVS相關症狀之患者，處理上要先有詳細的病史詢問及理學檢查，包括職業、電腦使用情形、疾病史、用藥史等，先排除其他可能之身體疾病。治療為多面相考量，除藥物之外還需許多非藥物的調整控制，如工作環境人體工學之設計、亮度、反光與眩光、適當眼鏡配戴及適時的休息等。由於電腦使用越來越普遍，CVS己儼然成為一新興之職業病，應對其有更深入之認識，才能進行有效的治療，並積極研擬改善預防之道，如此不僅能改善個人的健康，還可增加生產力及提高工作效率。

Taiwan Network Information Centre statistics revealed that there were up to more than 15 million people surf the net in Taiwan, more and more persons who cannot help to use the computer for a long time every day. However, operating the computer may have negative influences to the VDT (video display terminal) workers' health gradually. A lot of researches and papers about VDT safety and the impact on health have already been published. The most frequently health problem of the computer users are eye-related symptoms, such as eyestrain, dry eyes, irritation, burning sensation, redness, blurred vision and double vision. The term computer vision syndrome (CVS) is defined as a complex of above-mentioned eye and vision problems that are experienced during computer use. It is a repetitive strain injury. The mentioned symptoms are related to workplace lightening, glare, display quality and unique viewing condition. The longer time to use computer, the more chance to result in the eye-related problems. The treatment and prevention of CVS may require a multidirectional approach, including drugs, modifications in the ergonomics of the workplace, eyeglasses correction, lighting and environmental factors, and properly scheduled work breaks. Computers have become an irreplaceable necessity in our lives at work and home. As we continue to understand more about this syndrome, we will further protect our ocular health and thus prevent the future epidemic of the 21st century.
