The limitations of conventional goggles have caused immense inconvenience, and even damage, to the physical and mental health of healthcare workers. Hence, this study aimed to build a modified goggle (MG) with better physical performance. The temperature-humidity index (THI) was used as an indicator to investigate the impact of goggle-related heat strain on the ocular surface.
The basic functions of antifog, anti-ultraviolet (UV), and anti-blue-light radiation capabilities were evaluated. Furthermore, the clinical impact on noninvasive keratography tear film break-up time (NIKBUT), intraocular pressure, central corneal thickness, Schirmer test I, and the Dry Eye-related Quality of life Score (DEQS) were assessed in 40 healthcare workers by comparing MG with standard goggles (SG). The relationships between THI and the above parameters were explored.
MG had a significantly longer antifog time than SG (212.75 ± 23.95 vs. 138.35 ± 5.54 min, < 0.05), stronger antiultraviolet ability at 400 nm (99.99 vs. 45.55%), and optimal anti-blue-light performance at 440 nm (33.32 vs. 13.31%). Tear film stability after wearing the goggle was significantly worse than that before wearing them ( < 0.05). Both goggles achieved moderate to strong heat strain, with a THI of >80 at all timepoints. The MG group showed lower THI and DEQS and higher NIKBUT than the SG group ( < 0.05). THI was significantly correlated with DEQS, NIKBUT, and real fogging time ( = 0.876, -0.532, -0.406; < 0.05).
Wearing goggles for a long time may cause heat strain to the eyes, thereby leading to eye discomfort and changes in the microenvironment of the ocular surface. Our MG exhibited better antifog, antiultraviolet, and optimal anti-blue-light performance and lower heat strain than SG, thus making it ideally suited for healthcare workers.
传统护目镜存在诸多局限性，给医护人员的身心健康带来了极大的不便，甚至造成损伤。因此，本研究旨在构建一种具有更好物理性能的改良护目镜（MG）。本研究采用温湿度指数（THI）作为指标，研究护目镜相关热应激对视表的影响。
评估了防雾、防紫外线（UV）和防蓝光辐射的基本功能。此外，通过比较 MG 与标准护目镜（SG），评估了 40 名医护人员的非侵入性角膜地形图泪膜破裂时间（NIKBUT）、眼压、中央角膜厚度、Schirmer 试验 I 和干眼相关生活质量评分（DEQS）的临床影响。探讨了 THI 与上述参数之间的关系。
MG 的防雾时间明显长于 SG（212.75 ± 23.95 比 138.35 ± 5.54 min， < 0.05），在 400nm 时的抗紫外线能力更强（99.99 比 45.55%），在 440nm 时的抗蓝光性能最佳（33.32 比 13.31%）。佩戴护目镜后泪膜稳定性较佩戴前明显变差（ < 0.05）。两种护目镜均达到中度至重度热应激，所有时间点的 THI 均>80。MG 组的 THI 和 DEQS 低于 SG 组，NIKBUT 高于 SG 组（ < 0.05）。THI 与 DEQS、NIKBUT 和实际起雾时间显著相关（ = 0.876、-0.532、-0.406； < 0.05）。
长时间佩戴护目镜可能会对眼睛造成热应激，从而导致眼部不适和眼表微环境改变。我们的 MG 在防雾、抗紫外线和最佳抗蓝光性能方面优于 SG，热应激更低，因此非常适合医护人员使用。
