台灣驗光師對濾藍光鏡片處方的知識和態度

目的: 隨著數位設備使用頻率增加，藍光對視覺健康與濾藍光鏡片的臨床應用引發高度關注，然而現有研究多聚焦於鏡片的光學性質與短期效益，對實際處方者的認知與判斷模式仍缺乏實證資料。本研究旨在調查台灣驗光師對濾藍光鏡片處方之知識、態度與臨床行為，並探討其背後的影響因素。方法: 本研究採橫斷面設計，透過全國驗光師公會發放線上問卷，問卷涵蓋人口背景、藍光與電腦視覺症候群的知識、濾藍光鏡片的處方經驗與證據態度等四大面向。資料以描述性統計與邏輯迴歸分析進行處理。結果: 本研究共回收452份有效問卷，男性188人，女性264人，其中年資0~5年佔74.3%，中部地區佔55.3%，62.8%的驗光師認為日常環境暴露於藍光會導致視網膜損傷89.4%的驗光師認為藍光會調節人類的睡眠模式，72.6%的驗光師則認為電腦螢幕散發出的藍光會導致電腦視覺症候群。回歸分析指出，如果驗光師認為日常環境暴露於藍光會導致視網膜損傷(優勢比，odds ratio, OR 2.39, 95% CI 1.15 to 4.96, p=0.019 )，那他們於臨床開立濾藍光鏡片的可能性就越高。 結論: 台灣驗光師普遍具備藍光相關知識，並認為濾藍光鏡片與視網膜健康、睡眠品質及視覺疲勞具有關聯。然而驗配濾藍光鏡片的行為仍受到學歷、年資與執業場所等背景因素影響，部分行為更可能受到患者期待與商業資訊的驅動，而非實證基礎。未來應持續追蹤濾藍光鏡片相關人體實證之累積，並建立臨床建議準則。

Purpose:With the increasing use of digital devices, the impact of blue light on visual health and the clinical application of blue-filtering lenses has drawn growing attention. However, existing research primarily focuses on optical properties and short-term effects, while empirical studies examining the cognitive and behavioral patterns of prescribing professionals remain limited. This study aimed to investigate knowledge, attitudes, and clinical behaviors of Taiwanese optometrists regarding the prescription of blue light-filtering lenses, as well as the underlying factors influencing their decision-making. Methods:A cross-sectional design was adopted, and an online questionnaire was distributed via national optometric associations, The questionnaire comprised four domains: demographic information, knowledge of blue light and computer vision syndrome (CVS), prescribing experience, and attitudes toward scientific evidence. Data were analyzed using descriptive statistics and logistic regression.Results:A total of 452 valid questionnaires were collected in this study, including 188 males and 264 females. Among them, 74.3% had 0-5 years of experience, and 55.3% were from the central region. 62.8% of optometrists believed that daily exposure to blue light can cause retinal damage. 89.4% of optometrists believed that blue light can regulate human sleep patterns, and 72.6% of optometrists believed that blue light emitted by computer screens can cause computer vision syndrome. Regression analysis showed that if optometrists believed that daily exposure to blue light can cause retinal damage (odds ratio, OR 2.39, 95% CI 1.15 to 4.96, p=0.019), they were more likely to prescribe blue light filtering lenses in clinical practice.Conclusion:Taiwanese Optometrists generally have knowledge about blue light and believe that blue light filtering lenses are associated with retinal health, sleep quality, and visual fatigue. However, the behavior of fitting blue light filtering lenses is still affected by background factors such as education, years of experience, and place of practice. Some behaviors are more likely to be driven by patient expectations and commercial information rather than empirical basis. In the future, we should continue to track the accumulation of human evidence related to blue light filtering lenses and establish clinical recommendation guidelines.
