The use of swimming goggles (SG) has demonstrated to alter different ocular parameters, however, the impact of wearing SG on the tear film stability remain unknown. The main objective of this study was to determine the short-term effects of wearing SG on tear film surface quality break-up time (TFSQ-BUT).
Twenty-eight young healthy adults (14 men and 14 women) wore a drilled SG, and TFSQ-BUT was measured before, during and after SG use. Dynamic-area high-speed videokeratoscopy was used for the non-invasive assessment of TFSQ-BUT.
TFSQ-BUT was significantly reduced while SG wear in comparison to the baseline measurement (4.8 ± 4.5 s vs. 8.8 ± 6.9 s; corrected p-value = 0.017, d = 0.57, mean difference = 4.0 [0.6, 7.3]; 45% reduction). Immediately after SG removal, TFSQ-BUT rapidly recovered baseline levels (8.2 ± 5.9 s vs. 8.8 ± 6.9 s; corrected p-value = 0.744). The impact of wearing SG on TFSQ-BUT were independent of the gender of the participants (p = 0.934).
The use of SG induces a TFSQ-BUT reduction, with these changes returning to baseline levels immediately after SG removal. These data may be of relevance for the management of dry eye patients, who need to avoid circumstances that exacerbate tear film instability. Nevertheless, these results must be interpreted with caution since the experiment did not entirely mimic real-life conditions (e.g., eye cup piece drilled, time of exposure, environmental conditions). Future studies should consider the inclusion of dry eye patients and older individual in order to explore the generalizability of these findings.
游泳镜（SG）的使用已被证明会改变不同的眼部参数，但佩戴 SG 对泪膜稳定性的影响尚不清楚。本研究的主要目的是确定佩戴 SG 对泪膜表面质量破裂时间（TFSQ-BUT）的短期影响。
28 名年轻健康的成年人（14 名男性和 14 名女性）佩戴有孔的 SG，在佩戴 SG 前后和之后测量 TFSQ-BUT。动态面积高速视频角膜镜用于非侵入性评估 TFSQ-BUT。
与基线测量相比，佩戴 SG 时 TFSQ-BUT 显著降低（4.8±4.5s 比 8.8±6.9s；校正后的 p 值=0.017，d=0.57，平均差异=4.0[0.6，7.3]；减少 45%）。SG 去除后，TFSQ-BUT 迅速恢复基线水平（8.2±5.9s 比 8.8±6.9s；校正后的 p 值=0.744）。佩戴 SG 对 TFSQ-BUT 的影响与参与者的性别无关（p=0.934）。
佩戴 SG 会引起 TFSQ-BUT 减少，这些变化在 SG 去除后立即恢复到基线水平。这些数据可能与需要避免加剧泪膜不稳定的情况的干眼症患者的管理有关。然而，由于实验并未完全模拟实际情况（例如，眼罩片钻孔、暴露时间、环境条件），因此必须谨慎解释这些结果。未来的研究应考虑纳入干眼症患者和老年人，以探索这些发现的普遍性。
