To evaluate the quality, reliability, and educational content of YouTube videos related to soft contact lenses (CL).
An online YouTube search was performed for the terms contact lens and other common CL-related terms contact lens insertion and removal, contact lens wearing, and contact lens care. The first 50 videos were evaluated for each term. Videos were evaluated using three checklists (the modified DISCERN criteria, the Journal of the American Medical Association [JAMA] criteria, and Global Quality Score [GQS]). Video popularity was also evaluated using the video power index (VPI). Videos were classified into three groups according to the source of the upload; group 1: universities/occupational organizations, group 2: medical ad/profit-oriented companies, and group 3: independent users.
From among the 200 videos analyzed, 79 were included. The mean mDISCERN score of the videos was 2.34±1.39, the mean JAMA score was 1.20±0.99, and the mean GQS value was 3.47±1.28. There were positive correlations between the three checklists (P<0.001). Video power index was not correlated with each score. The videos in group 1 (13.9%) had the highest scores whereas videos in group 3 (41.8%) had the lowest scores. There was no significant difference between the video sources according to the VPI.
Although some YouTube videos contain useful information for CL wearers, most videos have poor quality and reliability and contain insufficient information. Eye care providers should be aware of these sources and steer CL users to information sources that provide accurate and reliable information and do not contain misleading information.
