摘要
目的研究使用增强现实(AR)眼镜和笔记本电脑在阅读效率和视觉疲劳方面的差异。研究方法进行前瞻性自控研究。在 2023 年 11 月 1 日至 11 月 15 日期间,在首都医科大学附属北京同仁医院招募了经常从事长期近距离工作并使用笔记本电脑和其他数字显示设备的首都医科大学健康学生作为受试者。对受试者的LogMAR视力、视功能(调节、辐辏和融合)和视疲劳评分(李克特视疲劳量表)进行了评估。每位参与者使用笔记本电脑和 AR 眼镜的顺序由掷硬币决定。测量了在不同日期同一时间使用不同设备阅读 10 分钟的效率(阅读速度和错误率乘以错误数字的检出率),以及观看 20 分钟视频后的视觉疲劳得分。统计分析采用配对 t 检验和 Wilcoxon 符号秩检验。结果:共纳入了 20 名符合条件的受试者,其中男性 7 人,女性 13 人,平均年龄为(25.45±2.27)岁。使用AR眼镜和笔记本电脑前后双眼视力无明显变化(P均大于0.05)。使用AR眼镜的阅读速度和阅读效率[分别为(34.03±9.25)和(29.19±7.62)位/分钟]明显低于使用笔记本电脑的阅读速度和阅读效率[分别为(39.43±10.36)和(35.67±9.87)位/分钟](t=4.36,Pt=1.29,P=0.213)。在使用两种设备观看视频之前,视觉疲劳得分没有明显的统计学差异(Z=-0.71,P=0.480)。然而,使用 AR 眼镜观看视频后的视觉疲劳得分[(20.55±5.04)分]明显高于使用笔记本电脑观看视频后的视觉疲劳得分[16.50(13.00,19.75)分](Z=-2.85,P=0.004)。使用两种设备观看视频后的视觉疲劳得分均明显高于使用前(PZ=-3.41,PC=0.004):在目前的技术水平下,与使用笔记本电脑相比,使用 AR 眼镜的阅读速度和效率更低,视觉疲劳更明显。AR眼镜需要进一步优化和改进。
[The impact of augmented reality glasses on human visual efficiency and digital eye fatigue].
Objective: To investigate the differences in reading efficiency and visual fatigue between the use of augmented reality (AR) glasses and laptops. Methods: A prospective self-controlled study was conducted. Healthy students from Capital Medical University who frequently engaged in long-term near work and used laptops and other digital display devices were recruited as subjects at Beijing Tongren Hospital, Capital Medical University between November 1 and November 15, 2023. LogMAR visual acuity, visual functions (accommodation, convergence, and fusion), and visual fatigue scores (Likert visual fatigue scale) of the participants were assessed. The order of using the laptop and AR glasses for each participant was determined by a coin toss. Reading efficiency (reading speed and error rate multiplied by the detection rate of incorrect numbers) with different devices for 10 minutes at the same time on different dates and visual fatigue scores after watching a 20-minute video were measured. Statistical analyses were performed using paired t-tests and Wilcoxon signed-rank tests. Results: A total of 20 eligible subjects were included, comprising 7 males and 13 females, with a mean age of (25.45±2.27) years. There was no significant change in binocular visual acuity before and after using AR glasses and laptops (both P>0.05). The reading speed and reading efficiency of using AR glasses [(34.03±9.25) and (29.19±7.62) digits/min, respectively] were significantly lower than those of using laptops [(39.43±10.36) and (35.67±9.87) digits/min, respectively] (t=4.36, P<0.001), while the difference in error detection rate was not statistically significant (t=1.29, P=0.213). There was no statistically significant difference in visual fatigue scores before watching videos with the two devices (Z=-0.71, P=0.480). However, the visual fatigue score after watching videos with AR glasses [(20.55±5.04) points] was significantly higher than that with laptops [16.50 (13.00, 19.75) points] (Z=-2.85, P=0.004). The visual fatigue scores after watching videos with both devices were significantly higher than before (P<0.05), with a more significant increase observed with AR glasses [(6.05±3.50) points] (Z=-3.41, P<0.001). Conclusion: Compared with using laptops, the reading speed and efficiency were lower, and the visual fatigue was more pronounced with the use of AR glasses at the current technical level. Further optimization and improvement of AR glasses are warranted.
